i have my first batch in the secondary, every thing was going well i did hydro test before i transfered it showed that it was done, then last night my heat quit in the garage where the beer was, the air temp got down to about 50 degrees i didnt have a thermomometer on my carboy but i dont think the beer got that cold it was covered. the garage has in floor radiant heat so ithink that helped, at what temp does the yeast die? i am just concerned about carbonation when i bottle, Thanks Ron
