Tomato Wine: Gold Nugget tomato’s first flower

I noticed the first flower among my gold nugget tomatoes a few days ago, and that marks another milestone on the path toward tomato wine.


A single five pointed yellow flower, the only one of its cluster that is blooming, stands out from the green foliage of this Gold Nugget tomato - 6/21/07


I took this photo on 6/21/07, and since then one or two other flowers have bloomed. These tomatoes are a lot more patient than I am. I’ve done my part. I tended them as seedlings, I transplanted them, and now its up to them. They’ve got flowers to open. They’ve got fruit to ripen! What are they waiting for?



White Wine From Tomatoes!

Different for a reason: Why I’ll make it white

When most people think about tomato wine, they – ok, most people don’t think about tomato wine, but if they did they would – think about red wine. It’s the same way with cherry wine, and just as I wrote about white cherry wine a few days ago, I’m going to make the case for white tomato wine today.

Since I’ve neither made nor tasted tomato wine before, I’m a little concerned about the taste. If there are objectionable flavors, then I think they’re most likely to come from the skin and pulp. A white wine is just fermented juice, so that would avoid the flavor compounds, good or bad, in the skins. As for the pulp, I’d want to stay away from sauce tomatoes, like Romas. In the end, I chose to make a clean dry white from Gold Nugget tomatoes. Gold Nugget is a cherry tomato with yellow/orange skin and yellow flesh that’s a reliable producer in this climate.

How to make it: Good fruit, balanced acid, and the right amount of alcohol

I have ten vines in the ground, and I don’t know how big a harvest to expect. I’ll pick each tomato when it’s ripe and put the day’s harvest right into the freezer. It won’t come in all at once, though, so I’ll store the fruit until the harvest is complete. That’s not the only thing about tomatoes that’s different from grapes. Tomatoes are about 95% water, by weight, compared to 80% for grapes.

The dominant acid in tomatoes is citric, rather than tartaric. I haven’t been able to find information on the acidity of tomato juice, but if the TA is low, then I’ll have to add acid to the must. In that case, I can choose one, or a combination, of the three major organic acids found in most fruit: citric, malic, and tartaric. Winemakers always use tartaric acid for any additions to conventional grape wine, but there are two schools of thought for acid additions to non-grape wine. The first approach is to use the dominant acid in the fruit. In the case of tomato wine, that would be citric. Another idea is to use a complementary acid. That is, instead of the dominant acid, add one of the other two. So I could use either malic or tartaric with this method. Should I need to acidify, I’ll probably use tartaric. I think it’ll make the a wine a little more familiar by giving it a bit of conventional white wine character. Also, I understand that citric acid can make the wine more vulnerable to vinegar spoilage and that malic can be harsher than the other two.

There will be a lot less sugar in the tomato juice, than in grape juice. I understand 5-8 degrees brix is common, so I’ll be adding sugar. It’s pretty straightforward to find out how much sugar to add for a given amount of alcohol. The question is, how much alcohol should I target? I often aim for 12% alcohol, by volume, in my wines and meads. That would be about 22 brix and a specific gravity of 1.090. Some research, by the late Dr Kime of Cornell, suggests that fruit wine (I’ve never liked that term – grapes aren’t fruit?) is better below 10.5% alcohol. There isn’t a whole lot of research into non-grape wine, so when a little bit come along, I pay attention. I’m leaning towards 10% alcohol for my tomato wine (18-19 brix, SG = 1.075). I’ve still got some blanks to fill in, but I’m getting a pretty good “big picture” idea of how I’ll make my white tomato wine.

Thinking about the next step

If this is a success, then I can continue investigating tomato wine. I don’t want to get ahead of myself, but I can see a red tomato wine next year. Red wine is all about the skins, and smaller fruit has more skin, pound for pound, than larger fruit. That’s why wine grapes are a lot smaller than the table grapes in the grocery store. So I would need cherry or grape tomatoes, for red wine, with deep dark color. I wonder if there are any dark colored small tomatoes that do well in this climate? I don’t know, but if my white tomato wine is a winner, then I’ve got plenty more to think about!

Update 12/22/2007: I finally did it!

The acidity of tomato juice is low, and I added tartaric acid just as I planned. I changed my mind about targeting a low alcohol level, and decided that my first tomato wine should be a more “normal” 12% alcohol. You can read all the details here.



Tomato Wine: Transplanted some more last night

I transplanted more Gold Nugget tomatoes last night, six more to what I’m calling the “east block.” That’s to distinguish them from the four in the “north block” that I transplanted on the 29th. I did it the same way: deep planting hole, pinched out the lower leaves, added a ground up antacid tablet and some homebrew organic fertilizer. So far so good. The north block tomatoes showed no signs of transplant shock at all.

In the photo, it’s hard to see all six Gold Nugget tomatoes, but the stem of the sixth one is just visible on the left side. The row of plants in the front of the tomatoes, the ones that look like onions, are onions (a man’s gotta eat too). So my tomato vineyard is a reality, with 10 vines in the ground! I’ve still got two in pots that I’m not sure what to do with.

Tomato Wine: Transplanted yesterday

I’ve been reading up on blossom end rot, and it turns out that there may be something to the old (I would have called it a “wive’s tale”) practice of putting some powdered antacid in the planting hole of each tomato. The rot is caused by a calcium deficiency in the fruit, and the calcium chloride in antacid tablets might be just the thing my tomatoes need.

So each tomato got one ground up antacid tablet. I mixed it, and a handful of my homebrew organic fertilizer, into the soil in the bottom of the planting hole.

Antacid tablet ground, homebrew organic fertilizer scooped, planting hole dug, we're go for transplant!

I ground up the antacid tablet, scooped out a bit of fertilizer, and dug the planting hole. I made the hole deeper than you’d expect just by looking at the plant or the pot it was in. That’s because I planted each tomato deeper in the soil than it was in the pot. I’m taking advantage of the tomato’s ability to easily grow new roots from the stem. Doing this puts the existing roots deep into the soil and stimulates new root growth from the just-buried stem.

Pulling the bottom leaves off the tomato to bury part of the stem

In the above photo, I’m pinching out some of the bottom leaves because that part of the stem will be underground. When all was said and done, I had four tomato plants tucked into their new bed.

Four just transplanted tomato plants and two foreground pepper plants

The two small plants, in the foreground of the photo that don’t look like tomato plants, aren’t tomato plants. They’re peppers, and I know that has nothing to do with tomato wine, or any other kind of wine. I do grow some things to eat, though, and they’ve got to go somewhere. So four pepper plants, I cropped the other two out of the photo, will be sharing some real estate with the “North Block” of my tomato vineyard.

Tomato Wine: Transplant day

Today’s the Day! Ok, I know I said that yesterday was also the day, but that was for racking the mead. Today’s the day for transplanting tomatoes. I’ve been anticipating and delaying for quite a while, but there’s some hot days (upper 70s Fahrenheit – about 25 or 26 Celsius) and warm nights (50F – 10C or higher) coming our way. Cooler weather arrives on or about June 4, and that worries me. By June 5, the overnight low sinks to 45F (about 7C), but I just cant see keeping my tomatoes in pots during June! I plan to transplant in the evening, transplant shock would be amplified during the afternoon, so pictures and details tomorrow!

Cluster Thinning For Better Tomatoes?

When I wrote about cluster thinning to improve wine grapes, it got me thinking about tomatoes. Could the same technique improve the quality of tomatoes (and wine made from them)? I always have a problem with blossom end rot on my Romas, and I think that may be clue.

This rot occurs because the plant can’t fully ripen it’s fruit, and it can be caused by improper watering, nutrient imbalance, or over cropping. I’ve tried to correct this problem by more careful watering and closer attention to the proportion of nutrients in my fertilizer, but with no success at all. Maybe I’m just not doing it right, or maybe those weren’t really my problems. Thinning has worked for me every time, and this makes me think that it might improve the fruit on other tomatoes, like the Gold Nuggets that I’m going to make wine from, that aren’t hit by blossom end rot.

Tomatoes aren’t grapes, of course, so there’s a limit to how much knowledge of one I can apply to the other. I’m not even going to try limiting fertilizer or water to my tomatoes, for example. I’ll probably try thinning, though, and maybe some other grape pruning ideas. I’ll keep you posted.

Tomato Wine: Transplanting delayed

I used to write software for a living, and one thorny issue never far form anyone’s mind was the release date. This was the result of changes, unexpected problems, negotiation, compromise, tests of will, overtime, threats of violence, and – ok maybe not threats of violence. Not explicit ones anyway. The point is that the actual date on which software gets delivered is often different from the date on which it was promised. So it is with my tomatoes (I never imagined those two sentences going together!).

Gold Nugget tomatoes are still in their pots on 5/24/07, and getting crowded

I had planned on transplanting them on the 22nd, but more recent forecasts tell of cold nights ahead. I want nice warm 50+ Fahrenheit (10+ Celsius) nights before I transplant them, and it looks like the 27th will see lows of 44F (a bit less than 7C). So I’ve slipped the release date, um delayed transplanting I mean, to the 29th. Once a software guy, always a software guy …

In the meantime, my tomatoes and other transplants (I do actually eat some of my vegetables) will commute to the patio every morning. And it’s getting to be quite a traffic jam in those pots.

One Step Closer To Tomato Wine

I’ve been looking at the 10-day forecast for clues on when to transplant my tomatoes. I wrote about the balancing act between trying to get them in the ground as soon as possible, so they can start spreading their roots in the soil right away, and keeping them from cold overnight lows that will hold back their growth. Well this morning’s forecast calls for overnight lows of 50 (10 Celsius) starting on 5/22, dipping to 47 (about 8 Celsius) on the 26th. Historical averages are 49-50 for the rest of the month. I think planting them on the 22nd would be a good balance between getting them in the ground early and keeping them from the cold. I’ll be keeping an eye on the forecast between now and then, but I’ve tentatively marked the 22nd as Transplant Day.

I’m tempted to say something like, “I can almost taste the tomato wine,” but I can’t because I have no idea what it will taste like. I’m still excited though!

Between A Pot And A Cold Place: When to transplant tomatoes outdoors

I’m making tomato wine this year, and for me that starts with growing tomatoes from seed. I transplant them into the garden when it gets warm enough, meaning overnight lows of 50 Fahrenheit or higher. The latest forecast is for lows in the mid 40’s for the next 10 days, though, so I should delay transplanting them because it’s still too cold.

The Gold Nuggets of my future tomato vineyard are getting crowded in their pots - 5/10/07

The photo above shows my Gold Nugget tomatoes on 5/10/07, and as you can see they are getting crowded in their pots. They need to go somewhere else soon, either the garden or other pots. No matter how carefully it’s done, digging up the plant and relocating it delivers a shock that temporarily stunts the plant’s growth. Repotting them would mean delivering this shock twice in a short time, once when I move them to new pots and again when I move them to the garden. So I should transplant into the garden right away to avoid this.

I’m not sure how I’ll resolve this dilemma yet.

Future Tomato Vineyard

Gold Nugget tomato seedlings barely an inch tall on 4/24/07For my tomato wine, I’m growing Gold Nuggets. They’re cherry tomatoes that turn yellow-orange when ripe; here’s how they looked on 4/24/07. In the ten days it took to expose the roll of film, process and digitize it, the seedling have grown from less than two inches to over four inches tall; maybe I need to rethink this whole digital camera fad 🙂
