Yeast starter/population lab work
« on: February 16, 2011, 04:20:42 PM »
There has been discussion lately about yeast starter population, dry yeast, and other related stuff lately.

If I were to do some lab work surrounding these topics, what would you like to see?

I've been wanting to see if the 40% viability figure for rehydrating dry yeast in wort is accurate. I'm waiting on a lab supply order for some methylene blue...

I've been trying to find yeast growth rate formulas that I could use to build a spreadsheet to help estimate growth in multi-step starters.

Have you already ordered? I can send you some powder.

Are you going to be testing a specific strain or manufacturer?

Thanks for the offer, but we're going to be placing a pretty large BSI order soon anyway. As far as strains, it'll be US-05 and W-34/70 since those are what we use for all our year-round beers.
