After freezing, thawing, and freezing my rhubarb again last Summer I finally got started on this a couple weeks ago but found the initial recipe a bit confusing. I read through all of the comments in this chain and have consolidated the answers to various questions along the way into a somewhat clarified set of instructions. This will make it easier for me so I figured I'd pass it along in case it helps anyone else.
This is a 1 gallon recipe. Multiply based on how much rhubarb you have. Don't multiply yeast.
3 lbs. rhubarb (stalk only)
1/4 pt. white grape concentrate or 1/2 lb. of light raisins (chopped)
7 pts. water (divided)
2 1/4 lbs. sugar
1/4 tsp. tannin
1 tsp. yeast nutrient
1 campden tablet (crushed & dissolved in small amount of water)
1 tsp. pectic enzyme
1 pkg. wine yeast (champagne) I used Montrachet
OG should be between 1.09 & 1.1
Use stalk only. Freeze fruit and then place in mesh bag and tie up. Place in primary and let thaw.
Dissolve sugar in a little boiling water (2 parts sugar/1 part water) and dissolve campden and pour over fruit (in mesh bag). Let sit 2-3 days, stirring daily, and keep pimary covered.
Then, strain fruit out and discard. Add all other ingredients (concentrate/raisins, tannin, yeast nutrient, pectic enzyme, enough cold water to hit OG) except yeast (maybe use the water to “rinse” rhubarb solids to get all juice & sugar out). Cover.
12 hours later, add yeast and stir well. Cover loosely with a towel for 2-3 days, then seal with a lid/airlock. Stir daily, breaking up cap.
When s.g reaches 1.020-1.040, rack into secondary, top up if needed, and attach airlock.
FG should be around .992
Rack as needed, adding campden every other racking (1/gallon). This throws a lot of lees, so you may need to rack as early as two weeks. Top up with white wine as necessary to avoid oxidation from excess head space. When there are no lees for at least 60 days, and the wine is clear and done fermenting, it is ready to bottle. Tastes best after at least one year.
FG should be around
Dry, this tastes a bit like pinot grigio. You may prefer it sweetened, but I don't sweeten.
Thanks Yooper! I can't wait to drink it.
