I didn't get to try too much as I showed up late, but the Grodziskie was great (although not authentic without the oak-smoked malt), there was a good Robust Porter going around, Richard's 10 minute Pale Ale was the best flavor for the length of the brew day, and I have to completely agree about Nigel's barley wine; really nice.
Next time i'll show up on time so I can try the chili porters.
