"I used to Brew Beer. But I'll tell you something: I would only brew it in the late evening. Oh, occasionally the early evening, but usually the late evening. Or the mid-evening. Just the early evening, mid-evening and late evening. Occasionally, early afternoon, early mid-afternoon, or perhaps the late-mid-afternoon. Oh, sometimes the early-mid-late-early morning ... But never at dusk. Never at dusk!"
-Apologies to Steve Martin
I have brewed at dusk BTW.
