CO2 Consumption Calculator

Someone on Reddit was wondering how many kegs a cylinder of CO2 would carbonate.  Using some constants from Wikipedia and absolutely no gas expansion temperature correction I made a quick spreadsheet to estimate the number.  Feel free to play with the input numbers to fit  your situation.   Here it is!

The gas density constant I used was calculated @ 32F, and with most kegerators being in the low 40s I figured this was close enough.

The “too long, didn’t read it” answer: for a 5 pound tank you’ll be able to force-carb about 17 5-gallon batches @ 2.5 volumes.

Below are the full equations I used.

Grain Storage

Because I very rarely brew the same thing twice I wind up with a lot of leftover specialty grains.  I had been storing them in a motley crew of plastic canisters, jelly jars, and plastic bags.  After losing track of what I had on hand and buying a few redundant grains I decided that I needed to be a bit more organized about this.  Many of my grains were in bags piled up in buckets which made them hard to find and easy to forget about.

I found some inexpensive square jars from US Plastic and bought a variety of the 128oz, 64oz, and 32oz jars.  The 128oz jar holds a little under 5# of grain.  I chose the square ones because they save space.

For my odds & ends I used the small 32oz jar plus some selected jars from my old collection.  I really just wanted to make sure that I could see what I have on hand.

Smaller Jars

For grains which I have a lot of I use Gamma Seals on hardware store 5-gallon pails.  Each holds around 21 pounds of grain.  US Plastic also sells the Gamma Seal, and this plus a $2.50 bucket makes for a relatively cheap way to store bulk grain – certainly cheaper than pet food containers.

Brewery Cleaning Area

Every brewery needs a way to clean things, but people’s methodologies don’t get much press because they’re usually the least-sexy parts of the brewery.  I’ve dual-purposed my laundry tub into a small brewery cleaning area.

Cheap Sink Facuet Controls the Garden Hose

When I bought my house this corner of the basement was almost ready for a washer / dryer as it there was a drain pipe and water nearby.  So when I ran the plumbing along the wall I also stubbed in tees for the hose.  The most useful part is the permanently plumbed-in garden hose.  In order to control the hold & cold water I bought the cheapest faucet I could find.  It’s a real piece of crap, all plastic, and I would not buy one again.  Off of that I split to the garden hose and my jet sprayer.

A piece of brass rod was used to give the sprayer some “backbone” as it would maddeningly flop all over without it.
