I have noticed on my last 3 (and only) kegged batches that there has been that weird cardboard taste. The last being the most severe. At first I thought it was the ingredients i was using, but I am starting to think it is my equipment or method.
This is the siphon that i have been using from morebeer:
This unit does work pretty flawless, excellent siphon with very little bubbles.
I am wondering if the initial blow to start the siphon maybe causing the oxidation.
I do purge my kegs after they are filled, but maybe I am not doing it enough. I am at loss and can't figure it out.
Anyone have any input?
