Notes

Both are California common strains that give a clean lager-like beer at warm temperatures, one liquid and one dry.

Choose M54 for a dry, shelf-stable strain you can pitch straight into a steam beer.

Choose WLP810 if you brew with liquid yeast and want to repitch the classic San Francisco strain.
