I also maintain the yeast bank for my club.  I have 25 strains on slants and also in glycerol stocks in a -80C freezer.  I am in the process of working out trades with other yeast ranchers to increase the selection (let me know if you are interested), and whenever a club member buys a strain that we don't have I take a sample.  I use 2ml screw cap tubes for my slants, so my 25 strains with 2 slants of each all fits in a little 6"x6" box in the fridge. 
When someone in the club wants to use a strain they have a choice of just taking a slant (after I pull a little from it to innoculate a replacement slant) to grow up a starter on their own, or I will step it up to pitching volume for them and they will cover the cost of the DME.  It hasn't been too popular so far, but I just started offering the service to the club and I think that it will be used more in the near future.

Where do you get your tubes at?

I just signed up to maintain the club's yeast bank. That should give me many more strains. So far I have about 10-15. Some might be dead though.

It all takes only a few plastic containers in which I keep the slants and stabs. Biggest problem is remembering to renew them about every 6-12 month.


I got started in yeast farming as a bank for the club.  As people get new yeast they try to get me a sample to culture and I make up starters for people who need them.  We're just a small group but we have been steadily adding strains. 

Does anyone have any specific information on using mineral oil?  Do you basically add sterile mineral oil to a slant to keep the oxygen off the cultures?

I keep my cultures on a combination of plates, slants, and stab cultures.  I'd like to try glycol freezing some cultures at some point but haven't had a chance yet....

All Grain Brewing / Re: Double pass milling
« on: January 06, 2010, 08:24:43 AM »
The thread on wet conditioning malt suggests that I offer another way to improve your crush and efficiency - double milling.  I have a motorized original adjustable JSP MaltMill (the original originals were non-adjustable because Jack though it was unnecessary to be able to adjust the gap, but he succumbed to pressure ;) ).

Anyway, I mill my grain at the wide open gap for the first pass, which breaks open the grains, then remill at the tightest gap, which doesn't affect the husks but makes nice, small pieces of endosperm with a minimum of flour.

I picked up this tip on HomeBrew Digest many years ago, and my efficiency jumped a few points, and I never (knock on wood) get stuck runoffs.


The 3 roller monster mills seem to be set up to do what you are doing with a single pass.  They sound pretty nice.  That being said my 2 roller mill does a good job and I have no need to replace it....

I've fly sparged both ways, keeping a steady bed of sparge water in and letting it run dry.  It seems to work either way but I've never really compared efficiencies, etc.  I've found that letting it run dry is easier because I have a measured amount of sparge water and once it runs through my kettle volume is usually just where I want it.

That being said I've been making the transition to batch sparging simply for the time savings of skipping the fly sparge and have had great results with that as well.

If anyone has noticed an efficiency difference with different methods of fly sparging I'd love to hear it.  I would think the biggest difference would come from the amount of time you spend doing the fly sparge

I would love to go pro but the student loans for my current career (veterinarian) cost way to much for me to afford on a brewer's salary right now  :-[

This is 5.5kg of MO treated with 250ml of water, stir well &  let soak for 15min  before grinding. As you can see the husk is in great shape while I have plenty of well cracked grain(flour).

I didn't calculate the efficiency on this one but the crush is just so aesthetically pleasing and easy to do that I plan to do it on all my brews from now on  ;D

Another Pale Ale. Brewing with my knucklehead friends. Nothing special.

However, I am prepping for a Stein beer project. Drilling granite blocks so I can rig it and drop the heated stones into a wooden brewing vessel.

Just finished drilling 9 granite blocks, which is harder than it sounds.

That's pretty cool.  My homebrew club it thinking about doing a steinbier this winter
