I just started a batch of this and wanted to ask a few questions.
I'm currently making a batch that will ultimately be 5 gallons of sweet wine. I'm using both liquid and frozen white and purple grape juice to get a light purple color. I'm using Montrachet yeast, which from what I understand, poops out around 13%, which means I should be able to get a medium strength wine. I'm kind of new to this stuff, and come from beer brewing, so please correct me if I'm doing something wrong.
What I plan to do is over a period of days, like with a really high gravity beer, I plan on adding, or staggering, my sugars (both table sugar and frozen concentrate). I will let the yeast catch up, convert most of the sugar, then add some more. I plan to continue this until the yeast die from alcohol poisoning, at which point I will add a little more sugar to finally sweeten the product.
Any issues with this?
