Winchester Straight Bourbon

Enter competitor TerrePURE Spirits, based in Charleston, South Carolina. A little Googling can tell you what you need to know about the technology, so I’ll just summarize it by saying that they use ultrasonic vibrations to induce chemical reactions in a young spirit (in this case, 2 year-old sourced bourbon), likely with inserted oak staves. This has a variety of effects, including filtering out congeners which cause off-flavors, building mouth-feel by esterification of fatty acids, and improving color absorption from the wood without added colorants.

Bomberger’s Declaration Bourbon

So what DO we know? Not much. … Michter’s releases have come from a variety of distilleries, by rumor, including old stocks of Stitzel-Weller (not anymore, I guarantee it), KBD (the logical choice), and possibly Brown-Forman. … The bottle claims the whiskey inside was distilled and bottled in Kentucky, and as a Straight Bourbon with no age statement, must be at least four years of age and aged in new charred oak barrels.

Elijah Craig Small Batch Bourbon

Elijah Craig is a small-batch bourbon made by prolific distiller Heaven Hill in Bardstown, Kentucky, and is named after Reverend Elijah Craig who is apocryphally credited with the invention of oak aging of corn whisky to create bourbon. This version replaces the old 12 year-old bottling, and is instead comprised of whiskey aged between 8 and 12 years.

Hirsch Small Batch Bourbon

Anchor Distillers (which is a distillery in California, but also does business importing and bottling sourced spirits) has loaded down the Hirsch label with every whisky marketing adjective in the book. This is – no, really – Small-Batch Reserve Selected Straight Bourbon Whiskey, which is “Crafted” in the USA. It also says “artisanally produced” on the back. I don’t think I’ve ever heard of anyone accusing MGP of being a “craft” distillery, but there’s the word on the bottle none-the-less.

Michter’s US*1 Bourbon

… industry contacts allowed the brand to distill its recipe under contract at an undisclosed Kentucky distillery. The recipe, incidentally, includes not only a specific strain of yeast and a mash bill of 79% corn, 11% rye, and 10% barley, but the unusual choice of filling barrels at 103 proof (instead of the more cost-effective 120+ proof).

Old Forester 1920 “Prohibition Style” Bourbon

Brown Forman’s Old Forester brand, in an attempt to avoid being left in the dust of the whisky hype train, is releasing a series of special-edition whiskies in honor of the brand’s history of per-Prohibition distillation. … uses a mashbill of 72% corn, 18% rye, and 10% malted barley (for enzymes), the same as other Old Forester bottlings, and is by law at least 4 years of age. The 115 proof (57.5% ABV) is the distiller’s estimate of the probable bottling proof that would have been used during Prohibition for whisky intended for “medicinal purposes”.

Sonoma County Distilling Co. Cask Strength Bourbon No. 2

Sonoma County Distilling, located in Rohnert Park, CA and opened in 2010, uses direct-fired copper alembic pot stills for its whiskies, which are twice-distilled (like most single-malt scotches, which are also distilled in pot stills). The West of Kentucky Bourbon No. 2 has a mashbill of Midwest yellow corn, unmalted Canadian wheat, and malted barley from Wyoming.
