Straight Edge Private Barrel Blend Bourbon 750ML

Straight Edge Private Barrel Blend Bourbon 750ML is a 42% ABV blend of Kentucky and Tennessee bourbons finished in Napa Valley Cabernet Sauvignon barrels. What distinguishes this expression is its secondary maturation in Mercury Head barrels — the same oak used for Splinter Group’s premium Cabernet Sauvignon — which layers dark fruit and wine-barrel complexity onto a traditional bourbon foundation. The Whiskey Wash scored it 86/100, and Whisky Connosr reviewer @Victor rated it 89/100.Quick Facts: ABV: 42% (84 Proof)  |  Origin: Napa Valley, California (sourced from Kentucky & Tennessee)  |  Blend of 5, 7, and 8-Year-Old Bourbons  |  Producer: Splinter Group SpiritsProduction & HeritageSplinter Group Spirits operates as a non-distilling producer based in Napa Valley. The bourbon itself is sourced from Kentucky and Tennessee distilleries and built from a mashbill of 70% corn, 17% rye, and 13% malted barley. The component whiskeys — aged five, seven, and eight years — are blended and then finished at the Splinter Group facility in Mercury Head Cabernet Sauvignon barrels, adding a wine-cask dimension rarely found in American whiskey. Originally aged at 124 proof, the spirit is proofed down to 84 using water drawn from aquifers at over 2,000 feet elevation in Sonoma County’s Alexander Valley.Tasting NotesAroma: Brown sugar and maple lead, followed by caramelized oak, orange peel, and exotic baking spices. A faint campfire smokiness sits underneath, adding depth without dominating.Taste: The entry is big and mouth-filling, with rich caramel and dark fruit — blackberry and currant — arriving immediately. Mid-palate brings warm rye spice and honey, while the Cabernet barrel influence weaves in a juicy, tannic undercurrent that sets it apart from standard bourbon profiles.Finish: Medium-long and smooth, closing with toasted oak, residual wine-barrel sweetness, and a honeyed warmth. The Cabernet cask echoes clearly at the end, leaving dried dark fruit and subtle vanilla.How to Drink Straight Edge BourbonAt 84 proof, Straight Edge drinks well neat or over a single large ice cube, which opens up the wine-barrel fruit notes without diluting the caramel core. It also works in cocktails that benefit from its fruit-forward profile.
Manhattan: The dark fruit and oak from the Cabernet finish complement sweet vermouth naturally, reducing the need for heavy bitters.
Boulevardier: Blackberry and currant notes stand up to Campari’s bitterness and add a wine-like richness to the drink.
Old Fashioned: The inherent sweetness and soft proof allow a lighter hand with simple syrup, letting the barrel character lead.
