So as the 7 isn't on distiller yet and I hate adding whiskies, I'll be doing 4 vs 7 and reviewing both here and when I see 7 up, I'll move it on over. Full disclosure I paid for the fusion 4 but 7 was given to me by the distillery. 4 Nose - The nose is opening up as classic Barton notes. Apple, light cinnamon, touch of oak spice and then there's a bit of an earthy element that you wouldn't get on barton. Overall it's VERY barton forward up front. Taste - And while the nose is all that 13 year barton, the taste is much more funky odd young bourbons with that sweet lovely barton on the finish. I don't really have a lot to say here, it's just not that interesting, but it's pretty boring and no descriptive. Overall - I don't mind this bottle and I've been working on just killing it to free up the space. There's this savory oily malty and youthful element I just can't get into. That said I think the barton is so young...it might really explode as it gets 5-6 years old. 7 Nose - White sugar and corn is really the upfront note here. Very clean and simple sweetness followed by funky bourbon. The rye here comes off burnt and very oak forward. It's an obvious blend of some likely heaven hill/beam type bourbons. Really heavy on that corn nut forward elements. Taste - Corn, sour, bitter, very low sweetness, tannic, and yet youthful. This is NOT good lol. Now I do have to say it's layered with a lot of depth and a lot of flavors, I just don't like any of it. But if you like something funky you might dig it. At the very last this is higher proof than the batch 4 and it has a really nice mouth feel. For me the 4 is a 1.5 and the 7 is a 1.25. Both are acceptable bourbons but they should be much cheaper, more in that 40 dollar range. I know they use some expensive sourced bourbon but their distillate isn't ready for the show to me.
