EW 1783 vs EW Black Label.
As far as I know, the Black Label is charcoal filtered and the 1783 is not. The Black Label reminds me a bit of Dickle, while the 1783 does not.
Still, I think they are damn good low cost whiskies. For under $35, you could have a bottle of each of the EW's and a bottle of Ancient Ancient Age 10 YO and, in this old fellow's opinion, you would be living well.
Each has plenty of aroma, flavor, character, smoothness, and a good finish. I could name a few much more expensive bourbons that these babies will put to shame...........but I won't cause my list would be different from yours anyway.
Salute to Evan Williams and Heaven Hill!!!!!!!
