I have asked questions about my wild grape wine project on several different threads. Today I was looking for some particular advice I had received and had trouble finding the right post. Since I have more questions (so, so many questions) I thought I would bring it together in one place so I can refer back to it as the wine ages.
First, my previous wine making experience is 10 gallons of apple wine that I made last year to excellent reviews by friends and family. This year, along with the wild grape, I am making a beet, elderberry, and apple. I decided on wild grape because the vines (Vitis riparia) around here had some of the biggest grapes I had seen and some of them were damn near edible! So I picked, manually destemmed, and froze 28lbs.
On 11/28 I put 24.3lbs of frozen grapes in straining bags, put them the in the primary, and added 8 quarts of boiling water with 9.8lbs of sugar. After crushing the grapes with a wine bottle and adding water to bring the volume up to 5 gallons, the SG was 1.062 so I added another 5.2lbs of sugar in 4 quarts of water. The starting SG was 1.114 and the pH was 3.06. I added 1.2g of K-meta and let it sit for 12 hours then added 6t of pectic enzyme and adjusted the pH to 3.15 with a small addition of calcium carb. At 24 hours I added rehydrated Lalvin 71b yeast. I stirred and pushed the bags down 2x per day. On 12/3 I realized I had forgotten the yeast energizer, so I added it at that time (6t). I pulled the seeds and skins on day 7 and manually squeezed out what I could.
I racked the wine on 12/8 when the SG was still 1.014 with a pH of 3.28. at the time it still had some of that that thick and sweet grapey flavor with a harsh alcohol taste. I ended up with 6 gallons. On 12/24 I racked again and made what I hope is an inconsequential error... I reported a hydrometer reading of 1.020 and leading to a suggestion that I try and restart a stuck fermentation, which I did by adding a starter of EC118 on 12/28. Looking back, I think I really was reading 1.002 on the hydrometer! The addition of the EC118 didn't seem to get any active ferment going and today the SG was 1.001. There are only the finest pin-prick bubbles rising in the neck of the carboy.
