The concept of Terroir in the Whisky World is a widely discussed concept and many opinions about the concept can be found on the internet. This page is not about the many different opinions about the concept, but it is about the science that investigates the concept. This page is also not meant to prove or disprove the concept. This page is about all the science that I have found available and what it tells me.
I have been blogging about Terroir in whisky for a while now and the amount of information has become so much that I have lost track of all the information I have already put on my blog. So this page is, mostly, for me to organise all the stuff.
Definitions of Terroir
For the definition of the word “Terroir” I am selecting (Choice) to use the definition provided by the Oxford Dictionary, Dictionary.com and Collins English Dictionary.
This Oxford Dictionary definition is given when you google “Define: Terroir“.
“The complete natural environment in which a particular wine is produced, including factors such as the soil, topography, and climate. The characteristic taste and flavour imparted to a wine by the environment in which it is produced.“Source: https://www.lexico.com/en/definition/terroir retrieved 29 November 2019
“1: The environmental conditions, especially soil and climate, in which grapes are grown and that give a wine its unique flavor and aroma:Source: https://www.dictionary.com/browse/terroir retrieved 29 November 2019
The high quality of the region’s terroir.
2: Also called goût de ter·roir [goo duh ter-wahr; gooduh ter-war] . the unique flavor and aroma of a wine that is attributed to the growing environment of the grapes.
3: The conditions in which a food is grown or produced and that give the food its unique characteristics:
grass-fed beef with an Idaho terroir.“
“winemaking: The combination of factors, including soil, climate and environment, that gives a wine its distinctive character”Source: https://www.collinsdictionary.com/dictionary/english/terroir retrieved 29 November 2019
I wanted to add something to sum up the definitions, but that would constitute an opinion. So no comments on the definitions. I did make some words BOLD.
List of Blog entries:
I have written multiple blogs about terroir and I have listed them below in order of publication:
- 28 Juli 2018: Does “Terroir” influence the Barley?
- 28 Juli 2018: Does “Terroir” influence the Whisky?
- 12 October 2018: Terroir has influence on flavour
- 3 January 2019: Whisky “Terroir” Research
- 3 February 2019: Focusing my Terroir Research
- 8 March 2019: Barley Terroir Investigations
- 17 May 2019: Terroir Research: Environmental impact on protein profiles
- 15 Juli 2019: What can Wine Grape Terroir teach Barley Terroir?
- 29 September 2019: Definitive Science Shows Terroir influences Whiskey
- 20 January 2020: Kew, et al. about “Whisky Terroir”
- 16 February 2020: Terroir: How Sensory Destructive is Distillation?
The earlier blogs will show I am establishing the concept and doing some binary thesis proving. The Thesis “Terroir has no influence on Whisky” was disproven in the first two blogs. A binary disproval of the concept that Terroir has no (please note the double negative) influence does not equal that the actual influence has a noticeable, significant or correlating impact on the sensory perception of the final product.
The rest of blogs are about what I found in science papers from that moment in time onwards.
Some blogs investigate the soil impact. Some blogs investigate the effects the environment has on the development of barley during growth.
Like I said, I am not writing an opinion about Terroir as influence on Whisky. I am listing the science. Do enjoy all the reading! Cheers!
