10 Barrel makes a very good one called Cucumber Crush.
I like the 10 Barrel - had a can of that one just a couple weeks ago. Also like the one we had at Historic Brewing in Williams, AZ a couple years back.
From the kegerator, it's a glass of home-brew. Head brewer Mrs D wasn't totally happy with the brown ale, so decided to turn it into a coffee brown ale...worked pretty well, just the right amount - can taste the espresso but it's not totally in your face.
