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 ...
Posted in thread: Firestone Walker Pale Ale from 2006 on 09-03-2014 at 02:58 AM
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...

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

CORRECTION: i just noticed that i had read my new gauge wrong. it wasn't 13.5 psi, it was 13.5
kPa, which is 1.958 psi. sorry everybody! so it was 3 min @ 2 psi/13.5 kPa thru a 2 micron
