Did it 6 weeks ago, or so. Popped one open now, and it is a real improvement. I don't have the space to do AG, and was worried that a PM wouldn't be enough to make much of a difference. But I did it mostly with Munich malt, and it gave it a really nice bready malty flavor that I can't get with extract alone. And it required little extra effort. Doing AG would be great, but PM is a really easy way for people without the space to make their beer better. PM it is from now on.
