I'm going to whip this up tomorrow and I have a couple of questions. Once it has fermented for 4 or 5 weeks, I plan on backsweetening with some concentrate, and I want it to be bottled and carbonated. If I bottle it immediately after backsweetening, it will carb up just like beer correct? And how do I keep the yeast from burning through all of it and drying up too much, or is that not a problem? Would pasteurizing the bottles be ok after it carbs up?
That will work. I would bottle one in a plastic bottle. When it is firm, you know it is time to pasteurize. It isn't without risks though.
