PR: Wissenschaftliche Studie im Auftrag von Waterford belegt Einfluss von Terroir auf Whiskygeschmack (+ Video)

Die Studie weist 42 Geschmackskomponenten im Whisky nach - die Hälfte davon wird direkt vom Terroir der Gerste beeinflusst

Mark Reynier, Gründer der in Irland beheimateten Waterford Distillery, hat es ja bereits in einem ausführlichlichen Video-Interview, das wir im letzten Herbst mit ihm führen konnten, angedeutet: Man habe eine wissenschaftliche Studie in Auftrag gegeben, die zweifelsfrei den Einfluss von Terroir, also von Boden, Lage und Klima, auf den Geschmack des Whiskys nachweisen und damit endgültig eine Antwort auf die langjährige Streitfrage darüber geben sollte.

Nun ist die Studie abgeschlossen und hat zusätzlich das peer-review durchlaufen, um jetzt in einem renommierten Fachmagazin publiziert zu werden. Um es kurz zusammenzufassen: Die Studie belegt den Einfluss von Terroir auf den Geschmack des Whiskys: Von den 42 verschiedenen Geschmackskomponenten im Whisky ist die Hälfte direkt von Terroir abhängig.

Zusatz am 18. 2. 2021: Diese Studie steht nun auch zum Download zur Verfügung:

  • New peer-reviewed research proves that concept of terroir is not unique to wine and cognac
  • Influence of soil, microclimate and topography on barley growth shown to have impact on flavour of whisky  
  • Debate about terroir has polarised the whisky industry for decades

17 February: A new academic study has provided conclusive proof of terroir’s influence on whisky, settling an industry-dividing debate for both whisky drinkers and producers alike.

The concept of terroir – the French principle that factors such as soil microclimate, and topography together can influence flavour characteristics – has long been accepted in other drinks categories such as wine and cognac, but has polarised whisky experts for years.

However, a peer-reviewed paper published today in leading scientific journal Foods, spearheaded by Waterford Distillery,proves that terroir can also be found in barley, and significantly, the single malt whisky spirit distilled from it.

The first paper from The Whisky Terroir Project examined two barley varieties grown on two farms with separate environments in 2017 and 2018: Athy, County Kildare and Bunclody, County Wexford in South Eastern Ireland.

Each sample of barley was micro-malted and micro-distilled in laboratory conditions to produce 32 different whisky distillate samples. These were then tested by world-leading whisky lab analysts and using the very latest analytical methods of Gas chromatography–mass spectrometry–olfactometry (GC/MS-O), as well as highly trained sensory experts.

Key findings include:

The findings of the study are significant for the whisky industry as the presence of terroir within the spirit distilled from barley creates the possibility of producing regionally specific whiskies in the same vein as wines, potentially an Appellation Controlée system of provenance.

Dr Dustin Herb, Lead Researcher and Post-doctoral research at Oregon State University, said:

“This interdisciplinary study investigated the basis of terroir by examining the genetic, physiological, and metabolic mechanisms of barley contributing to whisky flavour. Using standardised malting and distillation protocols, we preserved distinct flavours associated with the testing environments and observed year-to-year variations, indicating that terroir is a significant contributor to whisky flavour.”

Mark Reynier, Founder and CEO of Waterford, said:

“Barley is what makes single malt whisky the most flavoursome spirit in the world. This study proves that barley’s flavours are influenced by where it is grown, meaning – like wine and cognac – whisky’s taste is terroir-driven.”

“Critics claimed any terroir effect would be destroyed by the whisky-making process, saying there is no scientific evidence to prove that terroir even exists. Well, there is now.”

Waterford, a global whisky brand based in Ireland, uses a terroir-driven approach for all its single malt whiskies, with barley from each of its 40 Irish farms harvested, stored, malted and distilled separately each year. It has produced whisky from almost 100 different terroirs as Single Farm Origin distillations since it was founded.

Waterford’s Whisky Terroir Project was undertaken by a truly international team of academics from the USA, Scotland, Greece, Belgium and Ireland, including: Prof. Kieran Kilcawley and Maria Kyraleou of Teagasc Food Research Centre, part of the Irish Department of Agriculture, Food and the Marine; Enterprise Ireland; Minch Malt; and featured cooperation from Scotland’s leading whisky laboratory.

Professor Kieran Kilcawley, Principal Research Officer at Teagasc, said:

“We utilised gas chromatography olfactometry which enabled us to discern the most important volatile aroma compounds that impacted sensory perception of the new make spirit. This research not only highlights the importance of terrior, but also enhances our knowledge of key aroma compounds in whisky.”

This first step of the project explores the terroir impact via a laboratory malted and distilled spirit for complete production uniformity. The next stage – which will be published in 2022 – further explores the same role of terroir in whisky, this time using analysis based on Waterford Distillery’s own commercial spirit and matured whisky.
