Having recently gone to kegs, I have grown tired of waiting for my smaller 3/8 Autosiphon to rack 5 gallons from carboy to keg. I purchased the larger 1/2 model and 6ft of 1/2" id high temp, thermoplastic hose.
When I rack from vessel to vessel, I like to use a straight cane in the receiving vessel rather than just dangle the hose in it. Seems like too often the hose is yanked on and comes out spilling beer or wort all over the place.
Anyway, I used to use a 3/8 straight acrylic racking cane for this purpose. Now that I’ve gone to the 1/2 model, I need to come up with something to replace it.
I figured I could use a piece of 1/2 inch copper with a female threaded adapter on the end of it and a 1/2 inch pipe to barb fitting. I have a stainless one ready to go.
My question is will copper be OK in finished beer during the rack or is that a bad idea? Understand it’s perfectly OK with hot and cold wort, but maybe not beer due t o changes in PH.
I could do the same with a piece of CPVC I have lying around instead of the copper.
