I just came across this site today http://whiskey.findthebest.com/. It rates various spirits and you can select some and compare them side by side. The ratings are just mad.
Powers John's lane, Canadian Mist Black Diamond and Beam Red stag all get a 93 rating.
George Dickel Tennessee Whiskey got 90 and Bushmills 10 got 89.
Redbreast 15 got 82 the same as Devils cut Bourbon, Redbreast Cask Strength got 79 just shading Red Stag Spiced at 78.
At least Paddy 76 fared better than Fireball Cinnamon whiskey (I'm assuming with added anti-freeze since it's an American site) 95.
Just to annoy Luke they have Glendronach 15 year old Single Malt rated at 66 the same as Seven Troughs Distilling Co. Recession proof moonshine presented in a mason jar.
The results are based on various spirit competitions. 65% are based on San Francisco Spirit competition both recent and historical. You'll notice that there are a few bourbons that get 100 points.
you can also compare Vodkas, Brandy and Gins. Great fun for a wet Saturday afternoon.
