Re temps at the tail end of primary fermentation

Alison Crowe:

• Problem: Yeast died due to cold fermentation.
• Solution: Monitor fermentation temperatures and keep above 55 F. At the end of fermentation, when the yeasts are at their weakest, keep temperatures between 70 and 80 F.

Since our room does not dip below 72 F (so far) we're probably OK. Crowe also talks about fast and hot Cab S fermentation (up to 90 F), which clearly isn't our problem, and yeast nutrients, which we forewent.
