Storing Yeast Slurry

[Haussenbrau]

I will be making a lot of lagers this year with Safelager 34/70. I plan on trying to do some yeast rinsing and at least reusing the yeast for two generations.
I have a flask for the rinsing. I will use a combination of Starsan and boiling for the sanitation. There will generally be less than a week in between batches. I was thinking of sanitizing some 22 oz beer bottles to store the yeast, I will cap them with either sanitized cheesecloth or foil.

Are the 22 oz brown beer bottles a good idea? Or should I get some one quart mason jars?

Mason jars are better IMO but it's not going to hurt anything to store in beer bottles. But during storage you will want an airtight container so I would just cap the bottles when you store them.

+1 on wide mouth Mason jars. Easier to clean, fill, and pour. But bottles will work fine too. I'd probably foil the bottles in case there's still some fermentation going on. I had lids on mason jars bulge and even contort over longer time. At 38°F!

The slurry should be stored in the fridge, with the container filled to the top with starter beer or real beer and lidded. No cheesecloth, can't keep that sanitary.
