I’ve got a brew day planned for next weekend, when I’ll be making my first lager, specifically a doppelbock. While you can get away without a starter if you’re making a standard gravity ale, lagers are a different matter. You really shouldn’t brew a lager without making one.
A quick visit to Mr. Malty’s pitching rate calculator confirmed that the doppelbock starter was going to need a little more than 3 liters of wort and would take two packs of yeast. I settled on 3.5 liters, which meant 350 grams of light DME, plus the water. It was boiled for about ten minutes, then chilled. Once it was chilled, I transferred it to the jug, got the stir bar centered, which was harder than it sounds thanks to the slightly curved base of the jug, and then turned the stir plate on. Once I had it adjusted so that it was stable, I added the yeast.
It’s spinning now, and once it’s complete, I’ll cold crash the yeast and be ready to brew next weekend.
