How do you keep yeast starters from bubbling over?

[BrewerB]

My yeast starters are prepared in flasks, on a gas range stove top. It doesn't take much heat to get the wort boiling.

Problem is, each time I try this method, the wort ends up bubbling over the side. I thought perhaps this was due to my small 1L flask. However, same thing happened last night in my new 5L.

How do you prevent this from happening with your starters?

One thing that will help is putting a stir bar in there while you boil to give the bubbles a nucleation point.

The other is a drop or two of foam control.

The third is to put the flask only partway on the burner rather than centered right over it.

The best way, IMO, is to pressure-can a bunch of wort, then you can just open the jar and dump it in.

A JZ fan, huh? Yeah, I'll end up getting a pressure cooker one of these days.

I also love my pressure cooker for canning plain water which I can then use to rehydrate yeast, bloom gelatin, and wash/save yeast cakes.

Almost certainly, but no idea exactly what yet. I need to take inventory and see what I have that I can send.
