So I used gelatin for the first time on my most recent brew.. it looks fantastically clear when I bottled! But I have a concern.. due to life getting in the way.. it sat in the fridge with the gelatin for a week.. It should still have enough yeast to carb right? it's a 6.6% IPA. I know you only need to do this for a few days, but I should be fine right?
