Posted in thread: Lost Krausen thru blowoff tube, good or bad!?!? on 11-02-2015 at 07:02 PM
Davis Grad + BS Chemistry here. I'm only 4.5 years late to the party on this one, but the
krausen removal thing is something I've thought a lot about over the years, so here's what I
have to add to th...
Posted in thread: Is an infected beer infectious? on 09-03-2014 at 04:23 AM
The short answer to this question is "not really". beer spoilage is almost always wort
spoilage, meaning something went wrong at the beginning of fermentation and an undesirable
organism amplified up ...

I was living in Davis, CA in 2006, and all that year I was hooked on Firestone Walker's Pale
Ale. It wasn't called "31" back then, just Pale Ale. I've been back in Ohio since 2007 and we
don't get muc...

Posted in thread: Brita filters: What do they filter? on 07-01-2013 at 12:22 AM
when i saw it above, i assumed it meant "total hardness minerals", but i guess that's wrong. in
the context of a water report i think it means trihalomethanes. i've never seen trihalomethanes

hofmeister,Undergrad chemistry student and homebrewer here. Some thoughts on your questions:1)
BRITA FILTERS. Yes, Brita filters do indeed remove hardness from your tap water. I base this on
a few hou...
Posted in thread: O2 Results from my new O2 meter! on 02-21-2013 at 12:42 AM
thanks CWI. after thinking about your assessment of med cylinders and the backpressure being
overwhelmed, i'm inclined to agree with you. very interesting about the O2 bubble physics.
there's alot abo...
Posted in thread: Anyone use the disposable oxygen tanks for aerating? on 01-30-2013 at 06:15 PM
Clarification: CO2 is sold in pounds, but O2 is sold in cubic feet. this is because CO2
liquifies in the bottle, but O2 does not. now, in the big bulk tanks that the distributor uses
to store O2, it *...

yes, agree, 0.5 micron should in theory perform better. stay tuned!

i like the time unit-per-point of grav idea. hadn't thought of that. as long as you're seeing
vigorous ferments and good attenuation, it's all good. and i suspect you're right about smaller
