Title: Yeast starter
Post by: winstonia on September 16, 2014, 06:29:39 PM
Plan on making my first one of these, seems a bit odd as I'm used to dumping Us-05 into both my stouts and ipas.

Do I have to use LME or DME when making a starter? Also what's the time frame before pitching yeast, seems to be over 24hrs?

This calculator has me confused....

DME is easier to work with because you'd otherwise need to open a full can of LME to get the few spoonfuls you need.
use a 10:1 ratio water:DME - eg 1000ml water:100g DME.

Here's what I do:
Boil it up for 5-10 minutes, then cool it to a few degrees above the yeasts optimal fermenting temperature (eg 14-16 for lager yeast, 20-22 for ale yeast), shake well to aerate.
You want to have it comfortably warm for the yeast to have a party but not warm enough for it to turn into a freaky S&M yeast orgie.
swirl it up every time you pass it or stick it on a stirplate.
Ready to pitch in 24 hours.

Did one myself last night to bump up a 3 month old slurry from WLP001. 2 pints of water, with 1/2 cup dme boiled for 10 minutes. 10 hours later, there's a nice kreustan forming and its taking off.

Yeah I get it now cheers, just going to ignore that calculator.

Would this stuff do the trick?

Yup. The yeast just needs food.
