Sorry this may be a dumb question but I am new to kegging. I want to be able to give bottles to friends and was planning on kegging to carbonate. So the plan was to bottle from the keg but if I do so should I let them know they need to go right into the fridge if they don't drink right away or are they shelf stable as is? I wasn't going to add sulfite and just cold crash in the keg. Or is it possible to heat pasteurize them after bottling to make them shelf stable?
