This is probably a real n00b question, but I am doing AG and prefer 10g batches to make the most of my brewday. However, I can only get 2 cornys in my 5.2 cu ft refrigerator. I have a 2-tap tower and would like to have 2 different brews on tap. Anyway, can I fill a corny keg, purge with co2, and leave it under a few lbs of pressure and store it room temp for a couple of months before putting it into the fridge and tapping it?
