The first one after I quit using the Mr. Beer kits, batch 7 I think. I can't complain about Mr. Beer in general. It got me into the hobby, I enjoyed making the beer, it was a good learning experience, and I still use the LBK for small batches. But the first time I threw away everything except the LME and used fresh hops, DME and good yeast I thought, "Yes! That's beer!".
