My Black Raspberry Merlot Island Mist Kit is coming soon. I want to "bump" up the alcohol a bit so I ordered 1# of corn syrup and grape concentrate. When I add this sugar I wonder will this extend the fermenting time beyond the 5-7 day period?
Yes. But you should always check for yourself to know what you are really putting into your wine. If they have a combination of ingredients you may find that something else you were going to add is not needed.I bought the additives from Label Peelers. I will look at labels ingredients however I believe they are careful on that sorta thing. Right?
