> Ale yeast.....

Based on the accepted fact that ale yeast ferments down to near freezing, I
am curious to know what happens to wort/agar slants of yeast cultures stored
in the fridge.



What ale yeast is this?? Did you mean lager yeast. All the Ale yeasts I have
ever used tend to floculate out and go dormant when I drop them to cold
temperatures (like say below 45F), in fact I, and many many brewers
commerical and home, rely on this behavior to stop fermentation and
clarify the beer, it even has a technical name for it, called cold conditioning.

Care to enlighten us???
