-If your fermentation location is warm (around 80°F), let it ferment for 3 days.
- If your fermentation location is cooler, let your brewsy ferment in the warm, dark place for 5 days.
Give it a small taste-test after the allotted time. We're just tasting for sweetness right now, not flavor. The flavor will improve a lot when you put it in the fridge, but the sweetness level won’t change.
So, if it tastes a little too sweet, let it go for a few more days (about 2 to 4 more days). If it tastes WAY too sweet, check out the next section for some tips on how to warm it up.
After a few more days of fermentation, repeat the taste-test. When it’s the right level of sweet for you, you can pop it in the fridge.
The longer you leave your wine out in the warm, dark place, the drier it will become. So, it's okay to leave it out for a week or more if you like your wine really dry. But keep in mind that sometimes dry wine can taste quite acidic at first, so you may want to backsweeten after the next two steps (racking and cold-crashing).
