How long in the 200 ml starter? My normal starter routine is not great because I'm away for work a lot. I usually do 2L of 1.040 wort, pitch the yeast saturday and swirl often Saturday and Sunday. Then it just sits on its own until the following Friday when I chill it for pitching Saturday or Sunday the week following.
When stepping up should I follow the same process? (yes, buying a stir plate would be a wise investment...)
