Hi gents,
I've a whack ton of liquid and dried yeasts in my kegerator, a stir plate and some time to kill. I've been wondering, can I cook up a batch of DME and cold-store it, for grabbing some to propagate my yeast when needed. What's the downside to keeping unhopped boiled DME and store it at 4C for a longish time?
The alternate to DME is to mash some pale ale grains and store in a similar fashion (1.040ish OG), DME is pretty grim tasting, although I'd only use it to multiply the yeasty boys. It's pita to boil up and chill 2L at a time for propagation. Who buys 2x packets of 34/70 when one is enough when propagated and potentially split for future use.
Clean, sterilize and sanitize being the mantra of the day.
