Just finished reading Jamil's piece on Maibocks in the new BYO. He suggests using a 15 liter starter for 5 gallons of wort with an OG 1.070. A quick check with Mr Malty suggests that this can be reduced to 6 or so liters with the use of a stir plate. Since I only have a 2000 ml flask that left me with questions. What vessel would you use for such a large starter? And with that vessel could you still use a stir plate?
