I do not make starters... yet. But I will be soon and am looking into it closely now. After reviewing Mr. Malty's calculator for pitching rates and starters, I realized If I want to do a high gravity brew I may need a large starter volume.
For those of you doing 10+ gallon batches, do you get by with a 2000mL Erlenmeyer, or do you have something bigger?
My other thought was if I need a 4L starter (hypothetical), can I do a regular 2L starter, flocculate the yeast, decant the spent beer, and add a new 2L wort on top? Does this equal a 4L starter?
I am just curious because I think when I build my stir plate, if I need to accomodate a 4L vessel, I will need to make some power adjustments .
Thanks for the help and guidance!
