If I like my wine at an ABV of 1.010 for sweetness and I’ve let it go dry to .995, is there a calculation I can do to figure out the amount of sugar to add?
Yeah man. FermCal does it for ya. You plug in your numbers and it spits out your answer.
Here’s the link to fermcalc and a screenshot example if you had 6 gallons of wine http://www.fermcalc.com/FermCalcJS.html
