It's actually 86 proof and not 80 as this database states. Well, the extra 3% ABV feels more like 15% in terms of the smoothness. Even if the smell is nice bourbon-ish and woody with hint of alcohol (above common expectation), the first sip and the first taste is rough, oaky as fuck. Then I can feel sweet corn, probably only taste benefit of acclaimed "sour mash". I'm trying to dig some more on taste profile, other than overall sting and tangy taste, maybe fining hints of cinnamon, but that's all.
1783 "small batch" is more like party bourbon - you can spice some punch with it, mix it with a little bit of Coke, give some kick to your eggnog. I like that in it. But this is definitely not sipping material, if you're wandering (as I was before).
