yeast

[dliput]

Does anyone know if I have to make a yeast started if I want to take yeast from the end of a primary fermentation and reused it immediately in another batch that has similar ingredients?

Thanks

You can take the yeast and re-pitch it immediately, or even store it in a jar in the fridge for about 2 weeks or so, without needing to make a starter. The previous beer was essentially your starter.

If I'm pitching into a similar OG beer, I pitch about 1/3-1/4 of the yeast cake to allow for a little yeast growth in the new beer. I only make a starter every 3rd to 4th beer because I mostly re-pitch yeast.
