I have 5 gallons of Apfelwein in a Better Bottle since March 4. I want to bottle it soon, and carb it to 2.3 volumes. Is the yeast still viable? Will I need to add yeast at bottling time? This is my first try at it.
You'll be fine. Mine sat for a month and a half and carbed up just fine. In fact...I was stupid and bottled it in wine bottles not knowing they wouldn't hold carbonation. Had a few bombs before I got a chance to stick them all in the fridge. Sort of ruined the aging process, but oh well.
Yup, yeast should still be fine. I just carbed my first batch back in March after it sat in the primary for 4 months. Every one I've had has been perfectly carbed. Have no fear!
