Peated Whisky basics

I few weeks back I was lucky enough to attend the Whiskey Weekend event at Julio’s Liquor’s in Westbourgh, MA. They had a series of tasting events that lasted over several days, but the one I was most interested in was a tasting presented by Simon Brooking, US Beam Suntory Brand Ambassador. I have attend Simon’s tastings before and have always come away impressed.  He imparts wit, wisdom, and projects the best of Scottish hospitality…I always enjoy hearing Simon’s talks. This time, Simon presented a tasting called The Peated Malts of Distinction. It was a master class on how peat is used in scotch production and the regional differences that peat can impart…a kind of terroir, giving us, peated whisky.

Our peated malts for the tasting were a distinctive group


So, how much detail do you want me to give? We can really dive in the deep end (and you know I’d do it, too!). Or just a general overview? Can I get a show of hands? Four, five, six…ok, we’ll split the difference and go tiptoeing over the material. Here goes…

Peat is just decomposed plant materials in a water-saturated environment that is devoid of oxygen. Scotland’s peat bogs are all over the region, so the type of plant material that creates the peat varies…in the Highlands the peat is more pine based, while on the islands it’s seaweed based. This regional difference imparts the peat with different flavor profiles…Highland peat has less nitrogen compounds than Islay peat, so it will have a relatively low intensity of peaty character compared to Islay’s more intense character with high levels of smoke and burnt aromas.

Why do we care about peat in the first place? Peat is a fuel source and provides a hot but slow burn. Peat is used to dry the barley that has been partially germinated during the malting process, and the smoke imbues the malted barley with all sorts of flavors…aka some of the good stuff. Simon went into a lot of detail about each expression we were tasting, and I’ve included the highlights in my tasting notes below

I’m ready!


The Peated Malts of Distinction

From Beam Suntory at Julio’s Liquors, February 25, 2017


  • Western style, from Ireland
  • Connemara means “of the Sea”
  • Peat Phenols: 15 ppm (standard whiskies are 2-3 ppm)

  • Nose: light smoke, light peat, caramel and honey
  • Taste: light peat enters, honey, sweet, soft
  • Finish: smooth at end, honey lingers
  • Comments: Very nice


Glen Garrioch 1995

  • Pronounced “Glen Geery”
  • From the Highlands, Aberdeenshire
  • Phenols: 10-12 ppm

  • Nose: chocolate, soft spice, soft peat (very mild)
  • Taste: soft peat builds, starts sweet with honey and burnt sugar (matches the nose)
  • Finish: building smoke that lingers
  • Comments: Very good! I’d buy this one, but it isn’t available for purchase any longer (sadness)


Ardmore Legacy

  • From the Highlands, higher up in the mountains
  • Heather influence
  • Phenols: 15 ppm
  • 90% peated/10% unpeated

  • Nose: stronger peat nose, pine
  • Taste: smoky on tongue, little sweet but not aggressive, enters smooth, approachable for a medium peat; with water smooths out to more honey
  • Finish: smoke lasts on tongue; with water, softer smoke but nice


Hakushu 12 yr

  • Alps of Japan, Suntory Distillery
  • Phenols: some barley at 2-3 ppm and some at 25 ppm, then blended
  • Peat and barley are imported…difference is the water (soft, filtered naturally)
  • Altitude gives lighter, sweeter style spirit, Japanese style whisky

  • Nose: more body, not a lot of scent to discern
  • Taste: oily, smoke, sharper, camping, green apple
  • Finish: sharper smoke that lasts
  • Comments: very different and hard to discern


Bowmore 12 yr

  • Irom Islay
  • Means “the big turn”
  • Bowmore is in a more protected part of Islay
  • Barley is floor malted above the peat fired malt kilns and hot smoked
  • Aging caves below sea level…cool, damp climate for a softer, gentler maturation
  • Aged in bourbon and sherry casks

  • Nose: peatier
  • Taste: drier, smoke with iodine, plum
  • Finish: just the smoke, not sweet, alcohol
  • Comments: not heavy peat, subtle and smooth
  • Lustag Dry Sherry: plum, fruit, rich, sugar – tasted to see the influence on the whisky


Laphroaig Quarter Cask

  • Islay
  • Laphroaig means “the hollow by the bay”
  • Barley is floor malted above the peat fired malt kilns (peat heated, cooled, then more peat is packed to produce a blue smoke), smoked low and slow
  • Aged in Maker’s Mark bourbon barrels
  • Quarter Cask means more wood to whisky exposure giving more bourbon flavor

  • Nose: here’s the peat! ocean, greener, apple, smoke
  • Taste: starts sweet, then dries, oily, ocean; tasted with orange, cuts alcohol and gets drier and smoother
  • Finish: smoke that lasts; tasted with orange, sweet on tongue but doesn’t last
  • Comments: Smoke! My favorite!
  • Maker’s Mark Bourbon: lighter, spicier, with nutmeg, big and bold – tasted to see the influence on the whisky

I enjoyed the opportunity to compare all these different styles of peated whiskies. Being able to really detect the differences that the terroir gave to each expression helped me to open up my palate just that much more, and maybe gave me a few new adjectives to use as well. And as a person who loves to learn, I truly appreciated Simon’s presentation, giving details for each taste and an appropriate toast as well!

Got any comments about peated whisky? Do you like a lighter or a heavier style? Highland or Islay? Me, I’m definitely a peat girl, the smokier the better. It’s where I started this scotch journey after all!

Slainté! L’chaim! Cheers!
