Cell wall heath is the reason not just lag time. Hydrating the cell walls with water makes for stronger, healthier yeast. When it has to hydrate in sugar water (wort) it must work harder to get fully hydrated.is lag time the only difference maker?
i'm useingSafbrew S-33 yeast as per what came in the kit i ordered.
i feel fine with the rehydration process i'm just worried with all the excitement of my frist brew i may mess it up and be outta yeast.
