New Riff Cask Strength Sour Mash Single Malt Whiskey is a groundbreaking expression that defies category expectations. This American single malt is crafted using a sour mash fermentation process—a hallmark of Kentucky whiskey-making—and is bottled uncut and unfiltered at full cask strength. Aged for a minimum of 7 years, this whiskey boasts complexity and maturity far beyond its age.

The mash bill features an adventurous mix of six distinct malts, including caramel malt, honey malt, chocolate malt, and kiln coffee malt, lending a layered, bold flavor profile. Distilled and aged at New Riff’s modern distillery in Newport, KY, this whiskey delivers a uniquely American spin on single malt tradition, rich with depth, grain character, and a powerful finish.

  • 100% Malted Barley – Featuring 6 specialty malts

  • Cask Strength – Bottled at 113.8 proof (56.4% ABV)

FAQs:

Q: Is this considered a bourbon?
A: No. While made in Kentucky and using new oak barrels, this is a single malt whiskey made from 100% malted barley, not a bourbon mash bill.

Q: What’s special about sour mash in single malt?
A: Sour mash is traditionally used in bourbon-making. Its use here adds a tangy depth and a uniquely regional twist on the single malt category.

Q: Is it chill filtered?
A: No. This whiskey is non-chill filtered, preserving maximum flavor, mouthfeel, and complexity.

Q: Is this a limited release?
A: Yes. New Riff’s single malt series is batch-specific, and this particular cask strength release (Batch 23.01.106) is part of a limited allocation.

Q: Can I collect or gift this bottle?
A: Absolutely. With its luxurious black-and-gold packaging, high proof, and unique profile, this bottle makes a stunning addition to any whiskey lover's shelf or as a premium gift.
