If you have not tried Evan Williams Single Barrel Bourbon, you should. It is reasonably priced, and in my opinion, an excellent American Whiskey, one of the few under 90 proof American Whiskies I would go out of my way to find. And, to my knowledge it is readily available. Also in my opinion, it delivers that softer sweetness, and dare I say it, that almost delicate taste, that only Heaven Hill whiskies offer among American Whiskies. Their 'House Taste' offers a contrast with the other major distillers. None of these 'House Tastes' is really 'better' than the others, and they all offer something unique to the American Whiskey Drinker (that would be you, I presume?) .
So, explore and enjoy!
Now, being as how, in general, I prefer whiskey to be at least 90 proof, I wonder if there is a 90+ proof Evan Williams Single Barrel whiskey. Well, as it happens, Ezra B Single Barrel is a Heaven Hill product and is a bit older than Evan Williams Single Barrel (by two years) and is offered at 99 proof. This truly is a case of younger brother/older, stronger brother.
While I like EWBS so much because of its delicacy, I truly cannot say which of the two I prefer. So I suggest (you are curious about Bourbon, aren't you?) you buy a bottle of each and compare them.
Which ever one you like best, the other will still offer it own complete satisfaction with a nice contrast.
