Created Jan 27, 2010. I find touches of strawberry, plum and apricot as the first sip smolders on a long linger. Maker's 46 Bourbon is similar to Weller Full Proof because: it has a wheated mashbill, has the same above average amount of oak flavors, has a bit more noticable classic bourbon sweetness characteristics, has the same significant cinnamon flavors. Desiring Weller bourbons and having an incredibly difficult time finding them is often a bitter pill to swallow, but the fact still remains they are great bourbons.
WELLER FULL PROOF BOURBON PALATE: With an aggressive Kentucky Chew, Weller Full Proof gives the throat a little burn. It was then purchased by the legendary Edmund Haynes Taylor Jr in 1870, who named it OFC (Old Fashioned Copper) and invested heavily in its modernisation. The Kentucky straight bourbon is bottled without chill filtration. Yet as the heat fades, sweet corn and wheat mix with dark currents, gourmet raisins and fresh dried prunes. Rich toffee, vanilla, and apricot notes are on the palate.
Whiskybase is founded in 2007 with the goal to create the biggest resource of whisky information in the world. W. Weller Full Proof's full proof of 114 actual proof ( meaning it enters the barrel at 114 proof), or 57% ABV, is fairly robust in contrast to the more standard Weller 12 Year release, which is at 90 proof. Here comes another single barrel collaboration! According to the laws that govern bourbon distillation, the mash bill has to be made from at least 51% corn. Whiskey Type: Wheated Bourbon. Further identification: This is a future single barrel (Barrel #020) coming to Liquor Junction in MA hopefully by this Winter 2022. Buffalo Trace Distillery is a distillery in Frankfort, Kentucky, that is owned by the Sazerac Company. Bar owners and liquor stores who have selected barrels of Weller over the years will regularly request their bourbon to be non-chill filtered. I've got a good bit of Weller Full Proof store pick experience at this point - we are incredibly blessed with great distribution in Massachusetts it seems. There was also a distinct oak note on the nose, something I don't necessarily recall getting from a Weller Full Proof before. Bold and complex aromas of caramel, stone fruit, leather, and baking spice greet the nose with plenty of oakiness.
The flavor, interestingly, seemed to go a slightly different direction. It's a bit on the gentle side given its proof, forcing a swirl of the glass to liven it up. Doesn't have the same oak characteristics, while present, there is a pretty big drop in rich characteristics. I have far too much fun writing about whiskey and singlehandedly running The Whiskey Shelf to bring you independent, honest, and useful reviews, comparisons, and more. Price: $50 MSRP (good luck).
