I've never had much foam in a stirred starter before this round with 2565.
Yeah, I haven't been able to establish a pattern yeast to yeast. I always ferment at 68-70*F and have my starters on a stir plate. Some times they'd be mellow and other times they would gush. Add a couple drops of FermCap and it's the same every time and I can really fill up a "2000" ml flask without having to worry about it.
