We just got 1783 in our market and I've been tasting them head to head over the past couple of weeks. They are very similar but 1783 has a much nicer nose. Also a really noticeable spice flavor, nutmeg I think. I can't remember another pour where it was so prominent.
The price gap is a little wider here, about $5 difference on a liter.
Life's too short, and there's too much good whiskey within reach.
Liter pricing seems to be the wild card in other areas as well.
We're Bourbon Geeks, it's who we are, it's what we do.
