Hi All,

Here is a technique I came up with to brew multiple quart batches, at once, to try different ingredients.

Hope you find it useful!

Do I understand correctly that you are running your microwave for 60 minutes straight? How are you keeping that from boiling over? I've microwaved wort in a mason jar before and once it hits boil I have to stop it every few seconds and it never seems to get beyond that boilover stage.

He is using fermcap to prevent boilovers.

I'm still surprised he's getting no boilover even with the fermcap. I guess I am underestimating the power of fermcap.

Without Fermcap you do have to watch it and I have had to use the stop/start technique sometimes when I don't use Fermcap, but when you get past the hot break, it's fine. When not using fermcap, I keep the volume down to about 200ml.

i have been pondering this.  any particular reason to boil for so long if you don't do 60 minute additions? also i think a similar way of boiling would be just to get a canning kettle and put the beer jars into water that is boiling around them, you could probably control this a bit easier

Great question and I agree, in most situations 30 or even 15 minutes is enough. Jars in water will work but it takes a long time to boil. It's probably better to bring the wort to boil in a microwave and move it to a canning kettle for hop timings. Once you get the jars to boil, you're right, with a canning kettle you would get better control.
