I have seen some documentaries about making beer and whisky and they always show the yeast laboratory and you see people pulling out vials out of Liquid nitrogen and they use the same strain of yeast for years..

I am a bit lost here

The stuff in freezers is in glycerin. Glycerin does not freeze as easily and does not create ice crystals that tear cells. This is a cryogenic process and the lab freezer is - 80c

You've got me there! Some nice craft beer down there mind. Best were Barbarian Red and Barbarian IPA (pronounced Ee - Pee - Eh) which has "cantidades absurdas de lúpulo".
