My purchase was from around the beginning of the year, I believe. I contacted John back in July after brewing the two bad batches and tracing it to funky hops. What I already posted is basically what John told me.
Fair enough ^ thanks for the info.
First Brew was thanksgiving 2011, I'm at 99 batches and counting (as of 10/21/2014), and ran out of room in my signature to list them all.
