I was thinking of designing a nitrogen or helium(probably easier to obtain) blanketing system so I could rack from primary to secondary and secondary to bottling bucket without worrying about oxygen absorption. Basically it would consist of a hole drilled in the lid of the bucket for inserting the nitrogen tube and another with a loose flap of a cover to allow the nitrogen to escape as the beer fills the bucket. My question is, would this be practical? I found a disposable helium tank on the Target website for $50 that has 15 cu. ft of helium. A typical 6.5 gallon fermenting bucket is ~1.1 cu. ft. That means I could get 13 full uses out of the bottle before it ran out. That seems pretty reasonable to me. Any thoughts or things I may not have considered? Thanks.
