How do your top off? So I I take a can of concentrate and make 2 gallon of wine. After primary fermentation I can get 2 gallon filled. But then after 60 days once you rack off lees you end up with less liquid. What do you add to top up to control headspace? If you add water don't you run risk of weakening the wine? If you add more concentrate (making s point to buy 2 or more cans for wine and top off) wI'll you not just keep fermenration going? At least until the yeast fails. So what do you do? What's the best method? I was going to plan to make say 2.5 gallon and set .5 gal aside. Ferment all and use the .5 gal for topping off as main wine reduces with each racking over six months. And I was going to buy a second can of concentrate to top up the .5 gal bc let's face it there will be head space there once you start using it to top up the main wine. So what do you all do?
