Frozen LAB
My LAB culture froze recently. I imagine it would compromise the cultures, but maybe I stand to be corrected? Anyone had any experience with this happening?

The library says nothing about freezing LAB, so it cannot say whether a frozen culture is ruined.
- The Student's Manual says you may store the whey in the refrigerator to arrest the fermentation (Student's Manual, Basic Course, p. 18).
- Cho advises keeping the serum where there is little temperature change (Cho, Recipe, p. 55).
- A good culture should smell sweet.
- The manual says the yellow liquid is the LAB culture and must be kept alive (Student's Manual, Basic Course, p. 14).
Drake suggests a shop light nearby, or an oven near the pilot light, to keep a LAB culture warmer (Office Hours Feb 2025, 20:26).
