This past weekend (March 9, 2012) I started a new brew. I'm using Ram's Head Weizenbock from eBrew.com (Alternative Beverage). My yeast is Safbrew T-58 (10 grams). This isn't the yeast that Alternative Beverage specifically recommends but I have something in mind. I was looking for a yeast than can tolerate a high alcoholic content. I'll explain why later.
The first thing to do when preparing a brew session is to start your yeast. It needs to be active and ready to go to work when you pitch into the wort. I typically use the dry packs. Check the direction on the package to see if there are any temperature restrictions. I usually use 1-2 cups of water at ~80 F with 1 tbsp of powdered sugar. You can see here, after 45 minutes of brewing the yeast is alive and kicking.
