Cherry Wine Recipe: Bottled!

26 Replies

Sweet Cherry WineTwo years ago I set out to make wine from cherries the way you would make red wine from grapes. I bought 43 lb (19.5 kg) of Bing Cherries from Safeway, put them in a large picnic cooler, and crushed them the old fashioned way. Adjusting the sugar was a little tedious, but I was off to a great start. It turns out that the acidity of cherry wine is tough to get right, though, and in the end I sweetened it to balance tart tasting wine.

About the label

LouGarou is a talented photographer, and he was kind enough to let me use his photo in my wine label. He’s taken many exceptional shots, but the warm tones in this one made it just the thing for my label – thanks Lou!

I labeled it “Sweet Cherry,” and included alcohol content, TA, pH, and final gravity. Instead of a vintage (not too many people are going to be raving about “Safeway’s 2007 Bing Cherries”) I put a date range. The first date is the day I started and the end date is the day I bottled. You’ll know how long it bulk aged, how long it’s had in the bottle, and yes, when the cherries were grown – that date range says a lot without saying a lot.

How does the cherry wine taste?

I think I managed to balance the wine. The acidity is noticable, but it’s lively and not too tart. Sweetness is there too, but people who “don’t like sweet wine” liked it and didn’t think it was too sweet. I don’t notice the astringency that comes from tannin. This makes it an enjoyable red table wine, but unlike the dry reds that I’m used to. The flavor and aroma are different as well. I wouldn’t say it “tastes like cherries,” but there is something familiar from tasting commercial cherry wine (yes, there is such a thing).

Thoughts on my next cherry wine

This was a learning experience, and I’ve got a to-do list for the next one.

  • Use a yeast like Lavlin’s 71-B that consumes malic acid: since most of the acid in cherries is malic and I had trouble with too much acid, having the yeast remove some for me should make things easier.
  • Learn more about dealing with high titratable acidity (TA) and high pH at the same time: I’ve been reluctant to use phosphoric acid to adjust the pH because it can be dangerous to handle. Maybe I need to get comfortable with that or find another way to manipulate the different facets of acidity.
  • Learn more about cherries:  This is my second batch of cherry wine, and both batches had the high TA – high pH problem. Is it something about the variety of cherry (I used Bing each time)? how it’s grown? or are all cherries like that? I sense another know your ingredients post coming up.

Until then I’ll be enjoying my newly bottled cherry wine – cheers!

Know Your Ingredients: Rhubarb

2 Replies

Rhubarb is a high quality ingredient that can make a great, age-worthy wine. It’s also a versatile ingredient that shines in many different styles. To take advantage of its versatility, you need to know what it brings to your wine and what you need to add.

Sugar and acidity of rhubarb juice

So what does a winemaker need to know about rhubarb? The short answer is sugar and acid. Getting that right is the biggest part of any successful recipe. It turns out that rhubarb has a lot of acid and not much sugar. I juice the rhubarb and normally see measurments like this (these figure are from my most recent batch):

specific gravity (SG): 1.020, titratable acidity (TA): 14 g/L as tartaric, pH: 3.19

This agrees with Ben Rotter’s data:

SG: 1.020, TA: not enough data, pH: 3.17

Most of that acid, 70% or more, is malic.

Juice yield

A lot of people make rhubarb wine by fermenting on the fruit, and most recipes specify the amount of rhubarb by weight. To make sense of these recipes, or make wine with whole fruit, or to compare notes with other wine makers, you’ll need to know how much juice a given weight of rhubarb will yield. I got 515 ml (17.4 fl oz) of juice from 1.115 kg (2.5 lb) of fruit, or a yield of 462 ml/kg (7 fl oz/lb).

I froze the rhubarb, thawed it in a strainer and got 225 ml (7.6 fl oz) of “free run” juice. Then I lightly pressed, just squeezing with my hands, to get another 290 ml (9.8 fl oz). This is low compared to Mr. Rotter’s data (470 – 830 ml/kg). The pulp I discarded was wet, so I could have gotten more with a small press.

You know your own procedures better than I do. Do you efficiently squeeze the fruit leaving bone-dry pulp? Expect over 600 ml/kg (9.2 fl oz/lb). If you press lightly and leave wet pulp, then you’re more likely to get 500 ml/kg (7.7 fl oz/lb), give or take. Now we have some information on yield, sugar, and acidity. What can we do with these data?

The possibilities are endless

I normally make my rhubarb wine dry, and I can tell you it’s terrific that way. I’ve tasted sweet rhubarb wine that was fabulous. I’ve aged rhubarb wine over two years and noticed improvement. I’ve tasted 5+ year old rhubarb wine from the Montana Hutterites that was superb. I’ve heard that the Hutterites successfully age their wine for decades, and Ben Rotter aged a sweet rhubarb wine for 30 years, and it hadn’t past it’s peak. Many wine makers have found rhubarb to be an excellent blending wine.

This is what I mean when I say that rhubarb is versatile. That’s why no recipe can show you “what rhubarb wine tastes like”. To find out, you need to go beyond any one recipe and try different variations. Honey instead of sugar, sweet instead of dry, dry instead of sweet, high acid like a Riesling – and do set some bottles aside for extended ageing! While we’re on the subject of ageing, I wouldn’t recommend rhubarb as an early drinker. Even if you decide against extended ageing, you’ll want to give it at least a year.

Bonsai Vineyard: Drip Irrigation

4 Replies

With ten grape vines in pots, and another ten fruit trees, I’ve been doing a lot of hand watering. It’s become quite a chore, so I’ve decided to put in a drip irrigation system. This will have water coming from a garden hose, through a pressure reducing fitting, into a feeder bottle so that I can fertilize, through a half-inch hose, and out of quarter-inch drip lines that run to each pot. Instead of a seemingly endless cycle of fill the watering can – water the vines/trees, I would just be able to turn on the water and go read a book. With a timer, I might not even have to turn the water on and off.

I had an abstract idea of what a drip system was and how it worked. What I needed was some hands on knowledge – what were the various components of a drip system? what did they do? how did they fit together? For a crash course in Drip Irrigation 101, I went to three hardware stores. I struck gold at Lowes with a clerk who had been a plumber and installed many a drip system. Now I have most of the equipment I need and a much better idea of how to put that equipment to use.

    Basic equipment for a drip irrigation system

  • half-inch tubing – delivers low pressure water to the drip system
  • quarter-inch tubing – delivers water to an individual vine or tree
  • 25 PSI Pressure Regulator – keeps pressure from overwhelming the system
  • 3/4″ hose to 1/2″ tubing adapter – connects the system to a garden hose or tap
  • quarter-inch double barbed connectors – connects quarter inch tubing to the half inch tubing
  • 50 quarter-inch hole plugs – plugs holes in the half inch tubing

    Other equipment that might be needed

  • anti siphon device – prevents back flow from the drip system to the water supply
  • filter – keeps dirt from clogging the drip system

You can buy this equipment at a garden center as a kit or as separate pieces. I had planned to buy a kit, and use it as a learning tool, but the clerk at Lowes assembled everything I needed for the system I had in mind. If all goes well, I’ll be putting it all together into a working drip irrigation system for use this summer.
