They list these numbers on yeast packets for brewing too. Much better that your yeast spends as much time as possible fermenting instead of growing and budding. With an initial count and an idea of the age of the batch you can decide if you&#x27;re going to start the yeast in a small start batch(to prop up their numbers) or just plop the contents in.<p>What I&#x27;m trying to get at is a low dosage might mean the little critters take a while to reach a good population, while a high dosage might be what&#x27;s needed to discourage growth and encourage their reactions.
