If I had to go out on a limb I'd say the best straight whiskey on the market today is Four Roses Single Barrel. This bourbon consistently reaches the heights. It has a fine texture, soft mouth feel (despite the proof), fine wintergreen-like taste and aftertaste and balanced overall character with the wood char echoing in the aftertaste (but not dominating). Also, it has a fine natural sweetness. There are whiskeys from other concerns I would rate as high but they are not available (as yet anyway) in general circulation. I'd include the 20 year old rye we tasted recently at HH and the barrel strength 1792 we tasted at Barton's.
In any case, these are the three best whiskeys I've tasted this year and perhaps ever.
