Sauternes Casks & Whiskey

Sauternes Casks & Whiskey

It was a Sauternes cask finished scotch that kicked off my journey into Scotch (the old 12 year Glenmorangie Nectar d'Or).  I have since been collecting Scotches finished in ex-Sauternes casks and have converted a lot of my fellow whisky drinkers in trying and enjoying these types of finished whiskies.

So, what is Sauternes? 

Sauternes refers to a sweet white wine produced in the Sauternais region of the Bordeaux area in France. What makes Sauternes distinct is the way the grapes are affected by a particular type of mold called Botrytis cinerea, commonly known as "noble rot."

The grape varieties used in Sauternes wines include Sémillon, Sauvignon Blanc, and Muscadelle. The Botrytis mold penetrates the grape skins, causing them to shrivel and concentrate the sugars, acids, and flavors in the grape. This natural process results in grapes that are high in sugar content, which, when fermented, leads to a sweet and complex wine.

Sauternes wines are known for their luscious sweetness, richness, and a unique combination of flavors that can include honey, apricot, peach, marmalade, and sometimes a hint of botrytized character, which imparts a unique and desirable complexity. The high sugar content in the grapes often leads to a higher alcohol content in the finished wine.

The most famous estate in the Sauternes region is Château d'Yquem, which is renowned for producing some of the world's finest and most expensive sweet wines.

Sauternes wines are often enjoyed as a dessert wine, and they pair exceptionally well with various desserts, especially those that are not overly sweet, as the wine's sweetness can complement and balance the flavors.

Sauternes is an excellent example of how specific growing conditions, grape varieties, and winemaking techniques can come together to create a wine style that is unique and highly prized in the world of fine wines.

What can we expect from a whisky finished in a Sauternes cask?

A whiskey aged in a Sauternes cask can inherit a range of flavors and characteristics from the Sauternes wine. The impact of the Sauternes cask on the whiskey can vary depending on factors such as the type of whiskey, the length of aging, and the specific qualities of the Sauternes cask. Here are some common flavors associated with whiskey aged in Sauternes casks:

  1. Sweetness: Sauternes wines are known for their pronounced sweetness due to the concentrated sugars from the botrytized grapes. This sweetness can carry over to the whiskey, providing notes of honey, candied fruits, and syrupy sweetness.

  2. Stone Fruits: Sauternes is often characterized by flavors of stone fruits such as apricot, peach, and nectarine. These fruity notes can enhance the whiskey and contribute to a complex flavor profile.

  3. Citrus: Some Sauternes wines exhibit citrusy notes, which can add a bright and zesty character to the whiskey. Lemon and orange notes may be present, providing a refreshing element.

  4. Vanilla and Oak: Like other cask types, Sauternes casks can contribute vanilla and oak notes to the whiskey. The interaction between the spirit and the wood can enhance the overall richness and depth of the flavor profile.

  5. Spices: The influence of the Sauternes cask may introduce subtle spice notes, such as cinnamon or ginger, adding a layer of complexity to the whiskey's taste.

  6. Mouthfeel: Sauternes casks, like other wine casks, can impart a rounded and velvety mouthfeel to the whiskey, contributing to its overall texture and smoothness.

It's important to note that the influence of the cask on the whiskey is a dynamic process, and the final flavor profile is influenced by the interaction of the spirit with the wood and any residual wine flavors left in the cask. Whiskeys aged in Sauternes casks are often sought after for their unique and sophisticated flavor profiles, offering a departure from more traditional cask types like bourbon or sherry casks.

There are plenty of unpeated as well as peated expressions to try out if this seems like it could be something you would enjoy.  I would highly recommend giving it a try.  The Arran Sauternes cask should be a crowd pleaser if you don't know where to start.
