Most of the time, making a yeast starter is going to improve your batch of homebrew. In some cases, you can get away with pitching one homebrew-sized package of yeast, presuming the yeast is fresh. Earlier, I posted a chart of likely outcomes when a single liquid yeast package — containing around 100 billion cells (i.e. White Labs tubes and Wyeast XL smack packs) — is pitched. Today, I’ve included a chart for dried yeast sachets, which have somewhat higher cell count. However, there is a difference between getting away with something, and having something work optimally. And running the best possible fermentation is necessary if your goal is to brew the best possible beer. In this article, I’ll explain what I believe to be the best way to make a yeast starter.
