Big Yeast Starter

Going to brew on Sunday, 15 gallons of a Lemon Coriander Wheat beer, a recipe I have been refining for a few years.

I normally use Safale S-05 dry yeast, 2 packets for 10 gallons.  But I have heard about (and tasted) some good wheat beers made with the  Wyeast 1272 American Ale II strain.



I will ferment 10 gallons of the batch with this strain, and the third carboy will get it’s normal dose of S-05.

Since this is a liquid yeast smack pack, containing around 100 billion cells, I will need to effectively quadruple that for 10 gallons.  A 4 liter starter will more than do the trick.  If you aren’t sure how much yeast  you need for a given beer/batch size, the pitching rate calculator here is a great tool to use.

First, I prepare 4 liters of starter wort.  I added .8 lbs extra light DME to 4 liters of water and boiled for 20 minutes.  This gives an OG of about 1.035.

Next I chilled the starter down in a cold water bath.  Took about 30 minutes to chill down to pitching temps.  I added the stir bar while the wort was still hot in order to sanitize it.

Finally, I pitched the yeast into the starter, and got it going on the stirplate.
