What is the best way to handle the yeast?
If you look at the instructions in your wine kit (and please, do), they will likely instruct you to sprinkle your packet of yeast directly on to the must. Yet if you read the yeast package (and many winemaking textbooks) they recommend rehydrating the yeast. If the objective is to deliver the maximum number of yeast cells to the must, which technique is best? It turns out that the answer is not as simple as one or the other, but the main point is that rehydration is not really necessary. You can rehydrate your yeast if you absolutely want to, but be sure to do it accurately and precisely, as explained further below. The rest of us will tear open the package and dump it in, and spend the extra time sampling our last batch! When performed correctly, rehydrating gives the highest live cell counts, and the quickest, most thorough fermentation. The catch is, it has to be done precisely correctly.
