How smoked whisky is made

Smoked whisky is made by using peat as a fuel in the kiln to dry the malted barley.

Peat is nothing more then: Layers of semi-decomposed organic matter

The wetland conditions around many parts of Scotland lead to the creation of bogs: swampy, treeless landscapes covered in shrubby and mossy plants in wet, acidic soil. Because of these conditions, plants that fall into the bog, like grasses and mosses, decompose more slowly than usual and compress into layers of semi-decomposed organic matter called peat.

 

The kiln will burn the peat and the phenol parts will evaporate and will enter and stick to the drying malt. Its takes around 30 hours for the damp malt to be dried.  After the malt is dry the phenol parts will still be on and in the malt, and will be involved in the process of making the new make spirit. Some phenol are lost in distillation so the final PPM of the spirit is roughly one third of the original figure.

These are some effect that will determine the strength of the smokiness in the whisky: 

  • The amount of burned peat
  • Quality of the peat
  • Terrior of the peat
  • Heat of the kiln
  • How long the smoke is added too the drying malt 
  • The cut point of new make spirit.
  • Age of maturation 

PPM

 

Parts Phenol Per Million, is the amount of phenol will be in the whisky.

The PPM will determine if the whisky has a light, medium or heavy smoke taste in the whisky. But don’t get fouled by the PPM count. because its not the only thing that is important in a smokey whisky. 

A good example of  a whisky with a high PPM is the Bruichladdie’s, Octomore Masterclass 08.3 Edition.This will contain 309PPM, and is considerate one of the highest PPM whiskies out their. 

Will this mean you will get a slap in the face while drinking this? 

Well actually no, the PPM is not the only factor that counts. There are a couple of other factors that play a major part in peated whiskies.

Let me explain more down below.

Terrior

 

A word well known by wine producers and wine fanatics.

But not that well know in the whisky world( well..they are getting there).

By terrior they mean the soil, climate and sunshine that  part of that land gets.

This could mean, for example, that the terrior on Islay is different from the terrior on Orkney. 

But what does this mean for my whisky then?

Well the peat in Orkney is not the same as the peat in Islay. This will mean if you burn peat, it will contain several different parts of soil and phenol.

So the taste and strength of the peated whisky can therefore differ.. 

The balance of flavors in smoke will depend in part on the balance of lignin, cellulose, and hemicellulose in the material that is being burned.

More lignin and you get spicier, vanilla-ier, smokier flavors

More cellulose/hemicellulose and you’ll get more caramelly, toasty flavors.

Whisky fact:
"Peatlands cover less than 3% of the land surface of Earth in total, but are thought to contain twice as much carbon as the world's forests." Peat has been used as a fuel for centuries and is still sold to burn in fires to heat homes.

Does age make a difference?

It is estimated that the lost of ppm phenol of the new make spirit with 25 ppm with cask maturation will be around: 

  • 10 ppm after 10 years.
  • 8 ppm after 15 years.
  • 6 ppm after 30 years.

Please keep in mind this does not go for all the peated whiskies. This is because every distillery and whisky is different from each other. 

The fun thing is we can experience this ourself. 

Bottle half full or half empty?

Is my whisky light, medium or heavily peated?

 
 
There is a little phenol in every whisky. This is because it is already present in the barley. 
These fenols are not noticeable on the palate. 
 
The noticeable amount of peat varies from person to person. Each palate is different from another. 2% of the people do not even notice low peat content in their whisky. 
 
You can talk about peatiness in your whisky if the fenols (ppm) in the whisky is higher then 5 ppm. 
After 20 ppm you really starts to notice the peat in the whisky. 
 
Peatiness level  PPM on malt
Low 3 – 5 
Middle 5 – 20
Strong 20 – 40
Super 40 – 60
Ultra >60
Whisky fact:
Peat has been used as a fuel for centuries and is still sold to burn in fires to heat homes.

Taste notes of peated whisky

 

1.Phenol – medicinal, antiseptic, TCP

2.Guaiacol – burnt, smoky – but discernible in taste only

3.Syringol – burnt, smoky – but discernible in aroma only

4.Cresol – medicinal, earthy peat, tar

Im new too smokey whisky what would i start with? 

 

The most peated whisky are made on Islay. Islay is a island in Scotland where there are 9 different distilleries. all make their own quality and different  whiskies. These whiskies have a higher ppm and peat level then other whiskies in Scotland. 

To start with peated whiskies i would recommend something lightly peated at first. Like a Highland park 12 year old or a Benromach 10 year old.

This so your palate can learn and appreciate the peat taste. 

After you can appreciated the peatty taste you can dive into the world of peated whisky. The list below will let you see how much PPM their is in some of these peated whisky. 

But keep in mind: 

  • Age of the whisky 
  • Brand and style 
  • PPM
  • Terrior and region
  • Blend or single malt 

Hope you enjoy your peated whisky a bit more now with this knowledge.

Let me know what’s your favorite peated whisky is in the comments below?
