You just brewed a batch of beer, and your are waiting for the little yeasties to do their thing. So you can be forgiven if you go check to see if fermentation has started, say several times a day.
But once fermentation has started, and their really is no reason to go check your fermentor very often, how often do you find yourself going down into the basement, or out to the garage to check anyway?
The two batches I brewed yesterday are chugging away nicely, and yet I think I have been out there 5 times today already, to check again.
Why? I dont know, but there it is.
