So i decided to try grape wine last year since my friend had a backyard full of grapes that were going to go to waste. My process ended up a little complicated and now I wonder if it’s still ok.

I harvested as many grapes as I could around the end of September. I took as many as I thought I’d need to fill a 25L Demi, crushed and started fermenting a must and froze the rest of the grapes. I didn’t add any sugar, and also managed to completely forget to take a hydrometer reading.

The must started up within a day and was pushing the skins to the top for about 4-5 days (stirring the skins back in 2-3 times a day) then over the next 2-3 days it slowed and seemed more of less done so I filtered it into a Demi. It ended up to be only about 20 L so I knew I had to get it topped up. Likely with what I had frozen.

Before I got to making another small must I had to move. And whether it was the time it took to get settled in my new home or procrastination the 20L of wine sat in the Demi for about 2 months... By the time I got around to dealing with it I found it had a little patches of a white layer on top. I read it was typical with the space I had left, but it was salvageable. So I racked it to another Demi from the middle, below the top white layer and dosed it with campdon.

At the same time I had started a must with the grapes I had frozen. That fermented just as the last for about a week. Again I forget to measure hah. I pressed it and added it to the batch I recently racked. From racking I had lost a few L so I ended up still short..about 1.5L to be nice and full... I was out of grapes, a so I ended up adding some fresh, additive free grape juice, sealed it and moved on.

I put it in my cold cellar and within maybe 3 days or so it was bubbling fairly significantly. It’s been about 2 weeks now and it’s still got a slow but steady bubbles rising. Could it still be fermenting off the grape juice sugar I added? Or maybe it was stuck, or has some bacteria taken over or what..? Is it ruined? Or can I just dose it with campdon? I sort of didn’t want to

Any insight would be appreciated. Thanks 🙏
