I do see and understand the idea that it seems excessive for the cost and miniscule amount needed. I plan to put a batch in secondary for 14 days, hence the idea of removing the co2.

$2.99/lb so price isn't terrible

I did consider the damage. My carboys are both plastic so I may be OK. Glass would be a different story maybe. 1 oz isn't all that much I would figure you could have the carboy sitting in a warm water bath seeing as both plastic and glass are more conductive and not great insulators (correct me...

So, I am getting ready to rack into my secondary fermenter when it dawned on me, could you purge the air from a carboy with dry ice. I used the ideal gas law PV=nRT (hello high school chemistry) to calculate that I would need 1.23032 oz or 34.87901 g of dry ice to fill my five gallon carboy...

Update: 1 week after brewing and the blow off tube is still chugging away. Have some foam climbing up the inside about 3 inches or so. May leave it in primary a little longer.

I already had these hops left over from a different recipe.

Just crafted my first extract beer. (I know not very impressive. I don't have an all grain rig yet). Here is my brew log from my first batch. Also, I work in pipeline construction, hence the name. Recipe Link: http://www.brewersfriend.com/homebrew/recipe/view/460634/idiot-pipeliner-ale-ipa...
