Blueberry Wine: High maintenance but worth it

Blueberry Wine: High maintenance but worth it

Ah blueberry wine! One minute its fermenting up a storm, then next it’s a lifeless half-finished must that wont get going again. What’s really frustrating isn’t just that the old tricks don’t work – move it to a warmer room, make a fresh starter, apologizing (even if you don’t know what for) and so on – but that there was nothing wrong. It’s not an uncommon story on winemaking forums, and it happened to me recently. So what is it about blueberry wine that causes so many stuck fermentations?

It’s not Kryptonite

Or sorbate. Or any other substance in blueberries that are toxic to yeast. If there were something in blueberries that inhibited yeast, then it would become harder to ferment as you increased the concentration of fruit. 6 lb/gallon would be more difficult to ferment than 3 lb/gallon, for example, and 100% blueberries would be the toughest of all. But my own experience, and that of the only commercial blueberry winemaker I’ve talked to, is that 100% blueberry wines are the easiest to ferment.

Another thing: if it were some toxin or inhibitor in the blueberries, then it would be hardest on the yeast early on – when it’s struggling to come out of dormancy and grow. But when my blueberry wines have stuck, it’s been after a vigorous start. The large established colony of yeast then sputters at around SG 1.020 – 1.040. The question is, what changes between the promising start and the all too common fizzling out?

I’m trying to create an easy blueberry wine recipe, like my Apple Wine From Store-Bought Juice, and ran into this problem. My hope is to solve this problem and create a reliable and easy way to make blueberry wine.

Win her heart with constant attention. And pH management.

The first time I had a blueberry wine stick on me, I got it going again by adding nutrient. So I began to think that blueberries were low in nutrients. You know, if adding X fixed the problem, then there must not have been enough X to begin with, right? Not so fast. I wasn’t measuring pH back then, but I’ve since noticed that pH drops to dangerous levels as blueberry wine ferments. I now believe that my nutrient addition raised the wine’s pH  and that – not the availability of nutrient per se – got the yeast going again. That means you can’t just adjust the pH and other parameters at the beginning and think you’re done. You need to ensure that the pH stays optimal all the way through your fermentation.

Trouble-free blueberry wine: two ideas

I haven’t got this licked yet, but I have two things I want to try. Since there’s something about blueberry wine that’s causing stuck fermentation, blending with something else ought to help. And if I’m right about it being a problem of too-low pH, then blending with something else that tends toward high pH would help even more. Cherry wine is the obvious choice here because it settles at a high pH even when the titratable acidity is high. Like blueberry juice, cherry juice is readily available in grocery stores – it would fit right in with the easy recipe from juice that I’m trying to create.

The other idea is to keep this a 100% blueberry wine, but to attack the pH problem directly. What I want here is something I can add to buffer the fermenting wine at a higher pH. Sodium citrate or potassium citrate might do the trick. They are salts of citric acid, which is the dominant acid in blueberries, and are used as flavorings and buffering agents in the food industry.

Maybe one of these will do the trick. Maybe something else, but I feel like I’m getting close.

About the photo

It wasn’t just the color cast that made me think of blueberry wine. There’s something about the photo, from the exposure to the model’s pose and expression, that’s enticing but just out of reach. Blueberry wine can be like that. Herman Layos did a great job with this photo, and I really appreciate him making it available under a Creative Commons license – thanks Herman!

Notes

^BackNitrogen Fertilizers ~ Penn State Extension: this is an in depth look at using nitrogen in agriculture. What got my winemaking antenna quivering was this quote:

Anhydrous ammonia, urea, diammonium phosphate, and nitrogen solutions, when first applied, greatly but temporarily increase soil pH

I think the same thing can happen when we add DAP, or other nutrients, to our wine musts.



A New Look

Washington Winemaker has a new look! This is the biggest design change since going mobile, and it’s aimed at easy reading on the many flavors of tablet plus modern large desktops.

Mobile support is better too, with a custom search box to help you find exactly what you’re looking for on this site.

I hope I smoothed out all the rough edges, but if something broke during the upgrade please let me know. And if you like it as much as I, I’d love to hear that too!



Sweetening Wine With Splenda

Every time I’m asked about sweetening wine, I always say the same thing:

  • Ferment to dryness
  • stabilize with sulfite and sorbate
  • add a boiled-then-cooled sugar syrup to your desired level of sweetness

and I keep saying it because it works great: you have a lot of control and the risks (of infection or renewed fermentation) are low. But sometimes this approach doesn’t work well, like when you want a sweet bottle conditioned cider. In that case a sweetener that yeast can’t ferment, like Splenda, is just the thing. You can also use it to sweeten an ordinary still wine without having to stabilize it. To use a non-fermentable sweetener like Splenda, you first have think about how sweet to make your wine in terms of ordinary sugar.

Decide how sweet you want it

There are two approaches to deciding how much to sweeten your wine: you can “sweeten to taste” or you can use your knowledge and experience to set a specific goal (eg with this style of wine and so much acidity, I want that much residual sugar).

The “to taste” approach might be the way to go if you’re on unfamiliar ground. Maybe you’ve never made a mead before and you’re having trouble getting specific guidance on how much sugar (or honey, or something else) to add. You might take several samples and sweeten them by different amounts, let them rest for a month or so, then compare them. Or you might start sweetening the entire batch by some amount (10 g/L, say) letting it rest then tasting it. Up the amount by a little more (5 g/L maybe) and repeat until you get it just the way you like it.

If, on the other hand, you’re making a style of wine that has been thoroughly researched, you might have a concrete goal in mind.

Either way, you’ll come to some specific sugar concentration – for a series of bench trials, for the starting point in a longer iterative process, or because you have determined the final residual sugar that you want. Once you have that sugar concentration, that amount of sugar for whatever volume of wine you’re dealing with, you can use it to determine how much Splenda you need.

Granulated Splenda, 1.2 lb Bag, Sweetens like 10 lb of sugar

Convert to an equivalent amount of Splenda

It’s not as straightforward as it should be to convert an amount of sugar to an amount of Splenda. First of all, the company does not provide weight to weight conversions (you know, so many grams of sugar to one gram of Splenda for the same sweetness). They do provide volume conversions. More than one, in fact. The “granulated Splenda” that comes in boxes and is meant for cooking is volume-equivalent to table sugar. So one cup of sugar would be about as sweet as one cup of granulated Splenda, but one cup of the Splenda that comes in packets, that you might use for coffee, would be much sweeter.

Since granulated Splenda is meant to be measured and converted from sugar, that’s what I’ll talk about in this article. If you’d rather use the packets, you’ll need to contact McNeil Nutritionals, which sells Splenda in the USA, and ask them how (it’s not on the package).

Since it’s meant to be substituted for an equal volume of sugar, that’s what we’ll do. You can refer to this page of sugar info to convert sugar amounts from weight to volume. Then measure out the same volume of granulated Splenda. Ok the tricky part is over, now we can take our measured amount of Splenda and sweeten our wine just as we would with sugar.

Make a syrup and add to the wine

The best way to add most things to your wine is by dissolving them and adding them as a solution. With sugar, or Splenda, that means making a syrup in exactly the same way you’d make a sugar syrup.

It makes sense to use sugar in ordinary situations because it’s cheaper and doesn’t require conversions. Sometimes you need a non-fermentable sweetener, though, and this is the right tool for the job.

Washington State Liberalizes Liquor Sales

Supermarkets and other retailers start selling liquor in Washington State today! The final legal obstacle was overcome yesterday when those who benefited from the old patronage system lost their appeal to the Washington Supreme Court.

Washington has been a “control state” for almost eighty years. So people could only buy liquor like vodka and whiskey at state-owned stores. And even though we could buy beer and wine at grocery stores, archaic rules prevented them from using modern retailing practices. Retailers weren’t allowed to manage their inventory in warehouses, for example, and producers weren’t allowed to offer quantity discounts. Both were forced to go through privileged distributors.

Most of that is gone now that voters approved, and the court upheld, Initiative 1183 – I’ll drink to that!

Barefoot Zin vs Ravenswood Vintners Reserve

The Zinfandel is my favorite of the Barefoot offerings, and The Lady of the house and I tasted it blind against Ravens Wood Vintners Blend 2008 Zinfandel.

Running the numbers

I measured the pH, titratable acidity, and specific gravity of these two wines and combined them with the reported alcohol content in the table below. As you can see, they’re very similar:

Measurement Barefoot Ravens Wood
Alcohol: 13.5% 13.5%
Specific Gravity: 0.994 0.994
pH: 3.4 3.5
Titratable Acidity: 5.5 6



I strongly encourage you to measure and record as much as you can about the commercial wines you drink. Why? Well, I don’t know about you, but I’m not a trained lab technician and getting more practice will improve our technique. Some wineries publish their own analysis, and you can compare your own results against theirs – that’s valuable feedback that you can’t get on your rhubarb wine!

Knowing how a wine analyzes out can help you when you’re tasting that wine. That’s because you can learn why a wine tastes the way it does (or two similar wines taste different). Write down your measurements and your tasting notes often enough and you’ll begin to see patterns. Were those full bodied reds you like finished sweet or dry? How about those bracing whites that were so good in the summer? How come one acidic white was an easy drinker but the other one was so harsh? You’ll accumulate a lot of data, it will be tailored to you own tastes, and you can use that in your own winemaking. So instead of adding the juice of half a lemon because someone in an online forum said so, you’ll learn how to consistently make wine the way you like it – start measuring and take notes!

Barefoot a better value

We both thought the Ravens Wood was more complex. I thought that made it lively and a slight favorite over the Barefoot. The Lady of the House thought barefoot had a bold taste without being harsh and was like, “one solid note.” The Ravens Wood was like an orchestra with potential that hadn’t practiced together. Even though I liked the Ravens Wood a little better, it costs about 80% more (using the best prices I’ve seen) and it’s not that much better.

Your First Cider

I began thinking about apple cider last year, but this year I’m actually making some. I wanted to create an easy recipe so that most people could make their own cider, have fun doing it, and be proud of the result – a bit like the hard cider version of Leslie’s Apple Wine.

Ingredients: Apple juice and yeast

The juice can come from anywhere as long as it’s 100% apple juice with no preservatives. Advanced cider makers blend specific varietals to get just the right mix of acid, tannin, and sugar – not to mention flavor and aroma. For beginners I strongly recommend clarified, pasteurized juice. I’ll be using not-from-concentrate apple juice from Costco. From here you can just pour the juice into a fermenter and add yeast.

Wait! Don’t you have to measure the sugar and acidity? Aren’t they supposed to be within a certain range? Yes and yes, but if they were outside the broad targets for making cider, the juice wouldn’t taste very good (too flabby, too tart, too bland, etc …) so the manufacturer will be managing the sugar and acid of the commercial juice. Even though he won’t have cider in mind, you’ll probably be ok – I did say this was an easy recipe.

I really do encourage good measurements, though. Acidity should be between 3-5 g/L, as malic, or 3.4 – 5.6 g/L the way we usually measure wine (as tartaric). Specific gravity ought to be at least 1.045. If it’s not add sugar. For what it’s worth, I’ll be measuring.

Since the ingredient is just apple juice, the quantity is up to you. You want five gallons of cider? Use five gallons of juice. Have a small primary fermenter? Just use one gallon of juice. I’m using two gallons of juice and pouring it into a 3-gallon carboy – that will be my primary, and I’ll ferment it under an airlock. For each five gallons of juice, use one packet of yeast.

Best yeast for cider?

I think most yeast will work great – just keep in mind that each one has it’s own nutrient requirements, optimal temperature range, and alcohol tolerance. I usually recommend Red Star’s Premier Cuvee because it’s a reliable yeast that’s forgiving and gives good results. But I’m not taking my own advice this time.

I used to brew a lot of beer, and one yeast from my homebrewing days stands out: White Labs San Francisco Lager – it’s the only one I would pay up for. For this year’s cider, I’m using Wyeast California Lager (2112) a very similar (the same?) yeast that retains lager characteristics up to 65F. At $5/packet it’s not very economical, but it’s something I wanted to do – I’m hoping it’ll add something to the finished cider.

Procedure

  1. Optional: Measure the specific gravity and titratable acidity of your juice. Adjust to SG 1.045 – 1.065 and TA 3.4 – 5.6 g/L as malic.
  2. Pour juice into primary fermenter.
  3. Add yeast.

If you want to make it more complicated, check out the “Variations” section, below.

Why not press your own juice?


Crushing and pressing apples yourself can be rewarding, and you’ll be able to control the blend that goes into your cider. If you know what you’re doing, you have the equipment, and you have access to high quality cider apples, you can make better cider this way. But if you’re new to cider making, it will just add an extra step – keep it simple when you’re starting out, get the basics right, then you can decide if the equipment and time are worth the cost.

And for small batches, the cost will be high. A combination apple grinder/press like the one pictured will cost about $750. A machine like that can be invaluable to a backyard grower, but not for someone just starting out making cider or someone who just wants to make a gallon or two.

Finally, buying clarified juice – juice that looks clear to the eye, not cloudy with sediment at the bottom – means you don’t have to worry about fining. In practical terms, it means your cider will be ready sooner with less work.

Variations

Cider can be sweet or dry – carbonated or still. Dry, still ciders are the easiest to make, but a lot of people, especially those who are new to cider, will prefer sweet and/or carbonated ciders. You can sweeten a still cider the same way you would a wine. You can carbonated a dry cider the same way you would a beer. Producing a sweet carbonated cider is tougher. You should get a few completed ciders under your belt before you try. But it can be done.

One approach is to carbonate a dry cider the way you would a beer, but disgorge the spent yeast as in the traditional method of Champagne production, and then, without spilling, add a syrup made with sugar, sulfite, and sorbate. Then quickly cap with a crown cap. I don’t have the space to cover this here, and it’s an advanced technique – don’t try it your first time!

So yes, you can make it as complicated as you like. But for your first cider, get some juice, add some yeast, and make cider!

Blending for Better Wine

Think Blending-Not Varietals ~ Bert Dunn

A lot of people know about Canadian wine, but some still think its too cold for wine grapes. In much of Canada it is too cold for the wine grapes that we’re familiar with. But hardy wine growers tend hardy grapes in the Great White North, and they make good wine by blending. Varietals that survive and ripen in cold climates may not be able to rival traditional wine grapes on their own, but if you blend good components, the whole can be greater than the sum of the parts. I think fruit wine makers have something to learn from this and we can up our game by blending.

Three simple wines and some thoughts on blending them

I’ve made apple wine for years, but my recipe for a simple step by step apple wine recipe is more recent. It started with a comment from Leslie asking for a simple recipe. A quick answering comment grew up into a blog post: Leslie’s Apple Wine Recipe. I made this wine and I’m really happy with it; it’s an easy drinking white with good flavor and aroma. I plan to make more, lots more, but I’ve also been thinking about blending it with other “grocery store wines.”

Like my white wine from Welch’s grape juice. If you haven’t made this, you really should – it’ll surprise you. Here’s the recipe: Bailout Blanc. It’s cheap, easy (not like that! easy to make) and versatile. Pop open a bottle when neighbors drop by on a summer afternoon. Use it to top up almost any other wine you make. Not sure if that new white you brought home is worth buying more? Blind taste it against some Welch’s Wine. If it can’t clear that hurdle, and some can’t, you have your answer. It costs less than $1/bottle, and for that you get a lot. But you don’t get everything. For one thing, the aroma is lacking. Might blending produce a wine with better aroma? Maybe a little complexity? One idea is blending with apple wine, which has good flavor and aroma.

Another is to blend it with Produce Department Chablis. I made a balanced wine with no faults and nice aroma that was bland. Maybe blending it with Welch’s Wine would produce good flavor and aroma – a better wine than each was individually. I haven’t made wine from supermarket grapes again, but I might – if only to see what sort of alchemy I can cook up by blending it.

Have you tried blending? How’d it turn out? I’d love to hear about it.

Mead Lover’s Digest Shutting Down?

For those that don’t know, the Digest has been a great source of mead making information. I’ve read it for years, and I’d hate to see it go. Still, Dick Dunn, “the Digest janitor” as he likes to call himself, makes a good point:

it’s wrong to hold out the MLD as a potential resource for new meadmakers, and then not deliver the goods. There are 12 new subscribers just since the last digest, who’ve seen absolutely nothing.  And the digest content has been falling year-on-year since 2005

Dick’s announcement triggered an outpouring of support, and he agreed to keep it going for now. The only question now is, will we get meaningful traffic. I don’t know how (or when or if) this story will end, but I just want to say thank you Dick for providing a great resource!

Also of interest to mead makers

Got Mead is the largest mead making forum I know of.

If you could only buy one book on mead making, it would have to be Ken Schramm’s The Compleat Meadmaker.

My own Simple Mead Recipe is a great way to get started making mead.

Leslie’s Apple Wine – Bottled!

Leslie's Apple WineTen months ago I posted a simple recipe for apple wine, at the request of a reader:

I really want to try making apple wine. I know pretty much nothing about wine making. I know of a homebrew shop about 45 minutes from me. I need to know everything I will need to make a sweet apple wine, and I also need step-by-step instructions.

I created an easy recipe for Leslie on the fly. Now, it’s one thing to say that a recipe is easy to make, but how do you know until you try it yourself? That’s what I did, and I’m very happy with the result: an easy to make wine that was ready to bottle quickly and tastes good. What really jumped out at me from this experience was the importance of choosing between unfiltered and clarified juice.

Make wine fast with clarified juice

I’ve made a lot of apple wine, but this is the first time I used clarified juice. I would always buy unfiltered juice; it’s cloudy with a visible sediment at the bottom, and a lot of people (including me!) expect it to taste better than the bright clear juice that next to it on the grocery store shelf. To find out, I’d need to make two batches, as identical as I could except that one used clear juice and the other unfiltered, taste them blind and see. I haven’t done that, so I don’t know.

But I do know that if you want to make good wine quickly, the clarified juice wins hands down. I bottled bright clear wine ten months after pitching the yeast without fining. Doesn’t sound quick to you? It had been bulk aging for four months and hadn’t thrown sediment – not a hint, even after agitating. So I could have bottled four months earlier – that’s only five months after pitching the yeast.

Even accounting for delays or snafus, I’m confident I could bottle bright clear wine in six months every time. Faster with a fining regimen.

Be patient and take notes

Ready to bottle and ready to drink aren’t the same thing. It’s good now, but I’ve seen apple wine improve up to two years. So if you make this, try to spread it out. Drink some now, and open a bottle every few months. Take notes – even if you don’t think you have much to say. Was it smoother (harsher) than you remember? Is the aroma more or less pronounced? Or different in some other way? How about the color? Write it down! You’ll want to know this when you bottle your next batch.

Running the numbers

You’ll also want to know how the wine analyzed out. If you haven’t looked into the nitty gritty of calculating the alcohol content from specific gravity readings, you’ll be surprised at how complex and inexact it can be. I plugged in my original and final gravities into a number of online calculators, and got a range of 13.3% – 13.7%. I’ll save the discussion of just what goes into these calculations, and why different online calculators might not agree for another time. For now, I’ll just call it 13.5% alcohol. It had a final gravity of 0.994 and a TA of 6.5 g/L, as tartaric. pH was 3.5. On paper, it looks like a crisp, dry white.

How does the apple wine taste?

And that’s exactly what it tastes like. Apple wine can be fruity or neutral or anything in between. This one has good flavor, with a hint of apple, and a nice finish. I’ve tasted country wines that seemed watery, and others that were full bodied. This one was right in the middle with a just-right medium body. The aroma was muted and it had a refreshing acidity that wasn’t too tart.

About the label

A good wine deserves an attractive label, and for that you need good artwork. I struck gold when Courtney Bell agreed to let me use this image. The color scheme, the apples, and the first rate photography make it perfect on an apple wine label.

Since there isn’t a lot of room when it comes to the text, what you leave out is as important as what you put in. My labels usually have a header, “Apple Wine,” in this case. At the bottom goes a footer, and here I included my website url and a copyright notice from Courtney. Informational text includes the batch number, so I can refer to my notes, and some basic measurements.

What about your own labels? Think about wine that you’ve bought. Were you curious about something, but couldn’t find it on the label? Put that in yours. What about things that you glossed over? Don’t clutter up your label – leave those sorts of things out.

A great way to start

If you’re thinking about making wine, this recipe is a great way to start. By using clarified juice, you save a lot of steps like processing the fruit and fining the wine. That makes it an easy recipe that’s ready quickly. Another good choice is Welch’s Wine. So stop thinking about it and do it!
