Fermentation time

I am only fermenting 1 gal. of juice for my first batch of wine. Gas rapidly developed for a whole day, but now it's day 2 and it slowed down. Is it done, or should I leave it for a full week anyway?

 

Leave it for a month before you bottle. Patience is a virtue in this hobby, 1 week is beer brewing time. I'm fairly new, had a few batches that were kind of drinkable at 1 month, not bad at all at 3. And I don't know how they'd do longer, because I drank them 1 gallon test batches don't last long at all The longer you can stand to age the better off your product will be.

 

Get a hydrometer! When you have two readings the same at 1.000 or lower, it is done.

Time line is like this -
Primary is 3-14 days, or when SG is 1.030
Secondary for 3 weeks. Sulfite when racking off.
Next, let it go for three months before racking again.
Finally, after another three months, sulfite, sorbate, and then bottle. You can sweeten at this time if you want to.
