I have followed this recipe to where I have waited 30 days in the glass carboy and racked. This is where I had a small sip and wasn't sure if was good or not. I did not take the first couple SG readings, darn it!
RECIPE FOR CARAMBOLA (STAR FRUIT) WINE - (makes 1 gallon)
6-3/4 pts. distilled water (8 pints in a gallon)
2-1/2 to 4 lbs. star fruit
1 large lemon, juiced, or 1 tsp. acid blend
11-oz. can Welch's 100% White Grape Juice Frozen Concentrate
10 oz. very fine granulated sugar (regular white sugar)
1 crushed and dissolved Campden tablet
1/2 tsp. pectic enzyme
1 tsp. yeast nutrient
Sauterne, Hock or Champagne wine yeast
1/2 tsp. ascorbic acid (vitamin C)
Clean everything with acid wash, (instructions on bottle - .25 oz per 1.25 gal water)
Slice fruit thinly, place fruit and lemon in nylon straining bag and tie the bag closed.
Place in primary: water, bag with fruit, grape juice concentrate, sugar, 1 crushed Campden tablet. Read and record specific gravity (didn't do)
Wait 12 hours, add pectic enzyme into primary. Record specific gravity (didn't do)
Wait 12 hours, add activated yeast and again cover primary. Record specific gravity (didn't do again)
After fermentation becomes apparent, squeeze bag gently daily. Record specific gravity (1.045, next morning 1.01)
When specific gravity drops to 1.020 to 1.010, drip drain bag and transfer all liquid to glass carboy secondary. Top up with distilled water if necessary. Attach airlock.
Wait for fermentation to almost stop. Could be 2-3 days. Rack, top up with distilled water and refit airlock.
Wait 30 days and rack again. (Here is where I am)
Rack every 45-60 days until wine is clear and goes 30 days without dropping even a fine dusting of sediment.
Add another crushed and dissolved Campden tablet and the ascorbic acid, wait another 30 days and rack again.
Stabilize wine and sweeten to taste with sugar.
Even if you like your wine dry, sweeten a little and taste it. Sugar really brings up the flavor of camabola.
Wait 10-14 days and bottle.
