❓ Q&A: Common Questions About Whisky Types

Not exactly. While inspired by Scotch techniques, Japanese whisky emphasizes delicate flavor profiles and craftsmanship, giving it a unique identity.

That smokiness often comes from peat, a mossy organic matter used in the malting process. It’s especially common in whiskies from Islay.

You can, but they bring different flavors. Bourbon is often used in Old Fashioneds and Whiskey Sours, while Scotch is better sipped neat or in Rob Roys. Japanese whisky pairs well with highballs and minimal mixers.
