I was wondering what size flask and stir bar I should purchase to accomidate 5 gallon batches anywhere from 1.060 all the way up to 1.100? So far I'm thinkin a 3000ml flask and possible a 2inch stir bar (I think it only comes with a 1in)

Thoughts?

I have that plate ... I use 2000 mL flasks and one-inch bars. I think you could definitely fit a 3000 mL flask on it.

I just use a 1000ml and 1 inch bar and everything goes just fine, but I only do ten gallons at a time.

Is that a joke?

If you're planning on beers bigger than 1.070 then I would get a 3000L flask. Most of my starters blow out the top with my 2000L flask.

I'm going to buy a second 2000L flask to make it easier to do 10 gallon batches. That way I can do a separate starter for each 5 gallon fermenter.

Thanks. Any thoughts on the size of the stir bar?

I use 1 inch in the 2L flask. Should work for the 3L as well....you just need a slight whirlpool going. Maybe someone with a 3L flash will chime in.

Ok I'm assuming it comes with the 1" so I'll just start with that. Do you have this stir plate? Thoughts on it?

I've had really good luck using this: http://stirstarters.com/ with a 2L flask. It will purportedly use a 5L flask with no problem.

He is (was?) a vendor on here, and had a lifetime warranty. Lots of good reviews....

i second the 3L option. My little stirplate (computer fan type) would continually throw a 2" bar, the 1" does just fine. Plenty of action with it.

I have 2 laboratory style stir plates, 1 1/2 inch stir bars and 2000ml Erlenmeyer flasks and the only thing I would change would be larger flasks, 3000ml sounds like a good size.

Actually a 4L or gallon jug is nice for making 2L of Belgian starters, those thing have a krausen that won't quit. Fermcap S is an alternative for krausen minimization when using smaller flasks.

Here is a start beer, 800ml spilt into the two different carboys, with a brix of 12.8, hoping it finishes around 6 brix.

1000ml- 1 inch bar for 24hrs, but the real factor is how much yeast you put into the flask to begin with and how good you are at washing yeast. As I sure you already know.

I would recommend buying a Stirstarter instead. It comes with one (1"5/16") stir bar. I use a 4L flask on this with no problem. As the note on the Morebeer stir plate says you are paying $50 for "quality feel". Plus Stirstarter has Free Shipping
