Hello Everyone!
My wife and made our first one gallon "demonstration" batch of wine to see if we could even make a wine like substance back in mid-January of this year. So far things have gone well, due much in part to the knowledge base here that kept us from doing things we shouldn't, and focus on things we should (like cleaning/sanitization). At each racking we held back 250ml (separate from the main batch) and back sweetened the 250 ml to SG=1.005 to our taste preference. Consumed the 250 ml immediately just to learn the taste changes over time. We topped off the main batch each with any remnant red we had on hand to make up for the 250 ml we pulled out each time, on 2/25 and 5/28. Didn't know any better but it didn't seem to hurt anything.
So here's where we're stuck: We'd like to back sweeten and bottle what we have in bulk, but not sure what to add in terms of avoiding a fermentation restart, and simply preserving what we put in the bottle for a year (if it makes it that long before consumption). The wine making kit (bucket, siphon, airlocks, limited chems, etc.) we have from BSG came with Potassium Sorbate granules, and Campden tablets. Unfortunately we've found the BSG guide to be a little disjointed and not always reflecting current good practices we see discussed here. I noticed on many postings that there is frequently is a request for batch details needed to provide an answer, so I've written them below. Necessity for acid testing was a learning for us, so no early data.
Any thoughts or suggestions would be greatly appreciated!
Batch Details:
The batch recipe made on 1/17/21 was as follows:
1 gallon of Welches 100% grape juice
9 oz. sugar
1 Packet of red star yeast.
1 tsp . yeast nutrient
1 tsp acid blend
1/4 tsp. tannin.
Starting SG was 1.085, 0.993 after 7 days, and moved to secondary with airlock on 1/19 (Added Campden tablet).
Racked again 2/25, SG 0.993 (Added Campden tablet).
Racked again 5/28, SG still at 0.993, (titration kit arrived, tested out at .75% tartaric), Added Kieselsol and Chitosan (LD Carlson), to clear the batch.
