Hello All
I've been making starters in a 1000 mL flask for a while but I'd like
to bump that up to a gallon. I'm also considering a magnetic
stirrer. Do folks actually buy a stirrer large enough to handle a 1
gallon jug? I dunno if I'm willing to spring for such an expensive
device.
I'm thinking of getting the smaller stirrer from northern brewer and
using it for my 1 L starter flask, and then just stepping that up to a
1 gallon jug and letting it sit. Sound ok?
Also, if I'm making a starter for a hefe-weizen which will primary at
60 and secondary in the mid 50s (F) I should build the starter at 60F,
yes?
Thanks - JB

I've got a 2L flask that I use on my stirrer. Remember that the stirrer
will increase the cell count. A 2L flask on a stirrer is probably
at least equivalent to a 1 gallon starter without a stirrer. Depending
on who you believe, the 2L w/stirrer may even be significantly higher
than 1 gallon without the stirrer.

You are interested in promoting population growth in the starter, target your
temps for that. It does not matter what temp the beer is going to be
fermented at. IMO, room temp (70F or higher) for the starter is good, even
if you were using a lager yeast. I wouldn't put your starter in a
fermentation fridge or anything like that.

Hmm. I'd rather use a 2L flask than a gallon jug so I like this
idea. How long do you usually "build" a 2L starter prior to pitching?
Do you start it in a 1L flask and then step up once it ferments?

Ok. My freezer is getting full anyways.

Some people do that, I don't. I just make the wort in the 2L flask and
dump the contents of a WhiteLabs tube straight into it. I've never had any
problems doing it that way. Theoretically, the "ideal" way would be to
step it up, but I don't know how much difference it really makes.

Check eBay or other wscientidic surplus pages. I got mint for like 8
bucks -- it can handle a 3-gallon carboy.

No -- build your starter warm or room temp -- the goal is to create
yeast mass.You don't care about flavor. You'll pour the spent wort off
anyway prior to pitching.

Wow. I'll look.

Ok. Palmer suggests building a starter at the same temp and a similar
wort makeup as the target beer. Just curious. It did seem to me that
too low a temp on the starter would inhibit multiplication.

I disagree with his advice on the temperature (see my other post). With
regards to the wort makeup, I believe he was talking about using a malt
based starter solution as opposed to just refined sugar. IE, "similar wort
makeup" means that you want to use DME/LME or an all grain wort, it doesn't
mean that you need to use the same recipe or OG... etc. Just a basic wort
with light extract should be fine.
John.

Thate should be "mine" not "mint". The plate was anything but mint.

I doubt you really gain much of an advantage from either -- things will
just go slower. Also, I'd not go higher than 1.040 for starter wort. No
need to hop either.

Make sure you clean off all the ammonium nitrate, red phosphorous, and
pseudoephedrine before you get started...
