We sit down with master distiller Caitlin Bartlemay to dig into why American single malt keeps gaining ground and why McCarthy’s still stands out after decades on the shelf. We get practical about peat, Oregon oak maturation, proof, climate, and what it takes to steward a whiskey brand without chasing every trend.

• the rise of American single malt and what category recognition changes for shelves and menus
• Caitlin’s farm and winery background and how it shapes her approach to distilling
• learning the job through apprenticeship culture and the realities of early distillery work
• what defines McCarthy’s American single malt and why the core process stays consistent
• Oregon oak (Garryana) casks, reuse, cask sizes, and why time in wood is more than colour
• how warehouse climate affects proof and maturation at the base of Mount Hood
• why the six-year McCarthy’s is bottled at 100 proof and how it drinks
• tasting language, peat as an on-ramp, and the idea that whiskey should stop you mid sip
• limited experiments, special finishes, and where to watch for releases

A peated American single malt aged in Oregon oak shouldn’t work this well and that’s exactly why we had to talk about it. We’re joined by Caitlin Bartlemay, master distiller behind McCarthy’s American Single Malt, to unpack how a whiskey can be smoky, fruity, and bold without turning into a palate-wrecker. Along the way, we get into why American single malt keeps surging, what it means when stores finally label a real “American Single Malt” section, and why bourbon fans are starting to look for something beyond dessert flavours.

Caitlin brings a rare mix of backgrounds: farm kid problem-solving, years of winery work, and a food science education built on hands-on production. That story matters because it shows up in the way McCarthy’s is made and protected. We talk through the brand’s fingerprint: peated malted barley sourced from Scotland, copper distillation, glacial-fed water, and maturation in 100% Garryana (Oregon oak) barrels, including what happens when you reuse casks over multiple cycles and why “time in wood” is about more than extractive-heavy colour.

Then we taste and debate the six-year McCarthy’s at 100 proof, from smoke character to mouthfeel to the surprising ways peat can play like mezcal in a cocktail. We also touch experiments like rum cask aging, what trends get right and wrong, and how a whiskey should make you stop mid conversation and actually notice what’s in your glass.
