With so many different hops available these days, it's impossible for each homebrewer to brew all of them single-handedly. Jim's Beer Kit is a great place to read what worked for other homebrewers, but it's especially handy when commercial brewers do this "dirty-work" for us. I taste every single-hop beer I can find, and post ratings to Ratebeer, which serves as a handy online resource whenever I need to remember my impressions of a certain hop. It occured to me these thoughts might benefit other nerdy homebrewers on this forum too.
Disclaimer: these are my own subjective opinionated conclusions, based on just one sample, at one specific moment in time. I am frequently surprised by how much another brewer's results differ, even using the same single hop variety. Your mileage may vary, and I certainly don't think my taste buds are superior to anyone else's.
From my Ratebeer rating of Urban Chestnut Single Hop Trafalgar English Pale Ale
Aroma: 7 out of 10, Appearance: 4 out of 5, Taste: 8 out of 10 , Palate: 4 out of 5, Overall: 17 out of 20
Total Score: 4 out of 5
Tasted on tap at the brewery tasting room in a nonic pint glass. It poured a hazy amber/copper color with persistent white foam and sticky lace. Nice hoppy aromas from this rare French variety: Triskel, wildflowers, somehow gritty yet perfumey at the same time, definitely different (and less classically English profile) than the regular Trafalgar, husky grains, rising bread dough, freshly baked whole-grain bread, mild but very harmonious. Delicious, true-to-style English bitter flavors: sweet malts, biscuits, crackers, toasted nuts, light caramel, fruity ale yeast, apricots, orange rind and zest, lemon peel, cooked and caramelized fruitiness (marmalade is right) Light-medium carbonation, light-medium body, lingering fruity and bittersweet aftertaste. Tasty, easy-drinking, and well-balanced English ale, I would love to drink several at a sitting. I love this stuff, way to go Florian.
