Pumpkin Wine Recipe For Halloween
Oct 18th, 2007 by Erroll
How much pumpkin and acid?
This isn’t a common wine to make, even for a country wine, but I did find some recipes. Every single one of them agreed on using 5 lb/Gallon (600 g/L) of pumpkin, but they were very different in the amount of acid and sugar. I think it makes sense to use the 5 lb/Gallon of pumpkin, but aim for the acid and alcohol profile of a white wine. That means aiming for a specific gravity of 1.090 and a titratable acidity of 7-9 g/L. Adjusting the acidity will be pretty easy. After preparing the must, titrate a sample to get the TA, then add enough acid to bring it into the desired range. I can’t do the same thing with the sugar, though, because I’ll have to add so much of it. The 2-3 lb/Gallon (250 – 350 g/L) I expect to add, and the 2-3 cups/Gallon (125 – 200 ml/L) of water to dissolve it in, will increase the volume of must by 40 – 55%.
How much sugar?
That means I need to work backward from the total amount of sugar I want in the must. An SG of 1.090 implies 2 lb 6 oz of sugar per Gallon (284 g/L) of must. So if I knew how much sugar was in 5 lb of pumpkin flesh, I would subtract it from the total. How much sugar is in pumpkin flesh? On average about 4 – 6% by weight, so our 5 lb would contain about 3.2 – 4.8 oz (90 – 135 g) of sugar – lets call it 4 oz (110 g). Mashing the pumpkin will probably double that to 8 oz. That’s low enough that we could ignore the pumpkin’s contribution and still get pretty close, but now that we know let’s take that into account. For every gallon (3.785 L) of must, we’ll need 1 lb 14 oz (850 g) of sugar.
Putting it all together
In order to get a gallon of finished wine, I like to make my “1-gallon batches” anywhere between 1.25 and 1.5 gallons. You’ve heard of a “bakers dozen?” Think of this a the “winemaker’s gallon.” For 1.25 gallons (4.7 liters) of must, we’ll need 6.25 lb (2.8 kg) pumpkin flesh and 2 lb 6 oz (1075 grams) of sugar.
Ingredients
6.25 lb (2.8 kg) pumpkin flesh
2 lb 6 oz (1.075 kg) sugar
tartaric acid to 8 g/L
2 tsp (10 grams) DAP
0.25 tsp (0.6 grams) tannin
1.25 tsp amylase enzyme
1.25 tsp pectic enzyme
sulfite to 50 ppm (equivalent to 1 campden tablet)
Premier Cuvee yeast
Procedure
Remove the seeds from a pumpkin and peel it to get the flesh. Grate the flesh and bake at 350F (177C) for 30 minutes. Transfer to a pot and add amylase enzyme and enough water to cover. Heat to 150F (66C) and hold for 30 minutes.
While the pumpkin is baking/mashing, dissolve sugar in about a quart or a liter of water. Boil, then cool.
Strain the mash into your primary fermenter, add the sugar-water, then add cool enough water to bring it up to 1.25 gallons (4.7 liters). Add sulfite equivalent to one campden tablet.
When the must has cooled to about 70F (21C) or cooler, draw off a sample for testing. Measure the specific gravity (SG), the pH, and the titratable acidity (TA). Make a note of the SG.
Since we’re targeting a TA of 8 g/L, subtract the TA you measure from 8. Then multiply that number by the volume of must, in liters – 4.7 in this case. That will give you the amount of tartaric acid, in grams, to add to the must. There are about 5 grams of tartaric acid in a teaspoon, so you can divide the grams of tartaric acid by 5 to get the number of teaspoons. For example, if the TA is 2 g/L, then you would subtract 2 from 8 and get 6 g/L. Multiply this by 4.7L to get 28.2 g. Divide that by 5 g/tsp to get 5.64 teaspoons. I don’t know about you, but I don’t have a “0.64 tsp” measuring spoon, so we can round that to 5.5 tsp.
Thoroughly dissolve the tartaric acid, pectic enzyme, tannin, and DAP in a little water and add it to the must. Measure and record the pH. The TA should be 8 g/L. Cover and wait three hours for the pectic enzyme to work, then pitch the yeast.
It’s a bit more involved than other wines, but now that you know how, don’t you want to pour some pumpkin wine on Halloween?
So how did it end up tasting? Sounds interesting forsure.
Hi Jesse,
It was fun creating this recipe, and I was looking forward to making it. I got busy, though, and before I knew it Halloween came and went. After that, it went on the back burner. Maybe it’ll be a wine for next Halloween

Halloween, heck. How about a Harry Potter party?
Half Blood Prince is out on November 21…
Hadn’t thought of that, Shelby, but it might be a good fit.

I think you are a creative, interesting winemaker. I would very much like to know how your pumpkin wine comes out! I don’t have DAP, amylase enzyme, or a ph kit or acid kit. Do you think there is a way I could start this wine anyway (that is, leaving out those things) and still have decent wine in time for this Halloween (or next)? How would you do it given my equipment/ingredient shortcomings? Also, you speak often of a “bansai” vinyard and a “bansai” orchard in your possession. What is that? Got photos?
Hi John,
I’ve heard of people fermenting pumpkin without mashing, so you can do without the amylase.
It will be harder to get it right without TA and pH measurements, but it can be done. You will need to start with a small amount of acid, maybe one teaspoon, and then taste as the wine matures. Every time you rack, taste and make notes. If you think it needs more acid, add a little – no more than half a teaspoon . Don’t rush; expect to do this over the course of a year.
Tasting like this wont work until after it has fermented out, because the sugar in the must will mask the acidity. Also, young wine might not be very palatable, but you’ll have to ignore that and just pick out how “tart” or how “flabby” the wine is. I made wine this way before I got an acid test kit, and I didn’t always get it right. It can be done, though.
Without yeast nutrient, like DAP, you’ll be counting on whatever happens to be in the pumpkin flesh to sustain the yeast. If you go this rout, expect a slow and risky fermentation. If the fermentation sticks, it will be hard to diagnose and hard to get going again. I would strongly advise you to buy some nutrient. It’s easy to get by mail order and it’s not expensive.
I like making my own wine, but I love making wine from something I grew myself. I live in the suburbs, though, without enough room for a vineyard or an orchard. I grow grape vines and fruit trees anyway, its just that I keep them in large pots (5-gallon buckets, actually). Since they are so vigorous, I need to trim the roots every year to keep them healthy. So, I treat them like bonsai plants, at least below the soil, and that’s why I call the whole collection my “bonsai vineyard” and “bonsai orchard.” I have pictures of individual vines and trees, but now that you mention it, I don’t think I’ve taken a photo of the whole “orchard” or “vineyard.”
Maybe I’ll have to do that. Good luck with the pumpkin wine (do consider getting DAP)! I hope to make some myself.
And thank you very much for the kind words. I’ve been a little overwhelmed lately, but I hope to make more wine and write about it soon.
Erroll
Erroll,
Thank you for the detailed response. I guess I just didn’t know that DAP and yeast nutrient are the same thing. I do have nutrient, so all I’m lacking is the ability to test for PH and TA. I think I will bravely dive in and give this pumpkin wine a try anyway. And thank you for your helpful advice. Good luck with your future endeavors!
Sincerely,
John Hance
P.S. Where can I see pics of your “bosai” plants? Are they online? I saw some close-ups of grapes on your flikr acount, but I didn’t see the whole vine. I’ll go look again…
John,
I’m excited for you, and I hope you’ll let me know how it turns out.
Most of my grape vines are in five gallon buckets, but the Pinot Noir and the Swenson Red are in terracotta pots. Since they’ll look more presentable, I’ll go out and photograph them for you. I sometimes borrow a digital camera, but mainly shoot film. Once I’ve shot the roll, I’ll have it developed and scanned, then I’ll post the photos – bear with me!
Erroll
Erroll,
Don’t go out of your way for me. I’m just curious. I didn’t know you could successfully grow fruit trees in five gal buckets. Or grape vines, for that matter. Yeah; when you get around to shooting them I’d love to see them, but don’t put more on yourself for my curiosity’s sake.
Thanks again. I will be sure to let you know how my pumpkin wine comes out.
– John
Hello John,
I’ve taken some photos of my Pinot Noir, and once I have that roll of film processed, I’ll post them to the blog. In the meantime this post on pruning shows one of my grape vines out of the pot as I trim the roots.
I really would like to know how things go with the pumpkin wine!

I make it right in the pumpkin… it absorbs the pumpkin taste,but it quite sweet,and will sneak up on ya.Take out seed’s,add two lbs of suger,one packet of yeast,seal off as best you can,I use wax. let sitt till pumpkin starts too get really soft, poke a hole as low as you can too drain off, re drain if you want through a cheese cloth,or filter, chill and injoy.I do not sugest drinking if you have hi sugar !! Also do not drive
Right in the pumpkin? I’ve done some off-the-wall things in my winemaking, but that’s one I hadn’t thought of!
Right in the pumpkin, huh? That’s a wild idea. Would you call this “Pumpkin Pruno” (sorry, couldn’t resist)? I bet the boys in the big house would love to hear about this…
Sanford,
Looks like the recipe the old timers called “Pumpkin Jack”
I’ve yet to try it, but I have run across several variations of this using brown sugar, molasses, and raw sugar cane.
Basically, 2lb sugar to 1 quart water. Core the pumpkin to remove the seeds (smaller hole is better). Fill the pumpkin with warm water (not boiling! should be hot to the touch) and allow to cool, add yeast (1 yeast tablet or packet per quart of water), stir, cap and seal with wax. Place on a board with a hole drilled in it appropriately positioned to poke the drain hole in the bottom when ready. Soft pumpkins do not like being moved/handled and the board helps a lot.
Big pumpkin, big batch, small pumpkin, small batch. I was going to experiment this year, but like Errol posted, the time passed too quickly to grab a few pumpkins for this.
