Fill clean glass quart jars with the peaches, leaving a good inch of room at the top of the jar.
Add 2 T whey to each jar.
Add spices of your choice, as well as a little vanilla extract.
Add a pinch each of red pepper and salt.
Fill the jar with pure water to cover the peaches completely, leaving an inch of room at the top of the jar for expansion.
Put a lid on the jar and store in a cool place, like a basement, for two days (or until the peaches reach your desired flavor).
Check your peaches multiple times to make sure they're not getting more fermented than you'd like.
When the peaches reach your desired level of fermentation, put them in the refrigerator to stop further fermentation.
