You may have heard the term 'single cask' being thrown around. But what exactly makes these whiskies so special? Let's take a closer look.

Firstly, the term 'single' can be misleading, as single malt can come from a variety of casks. Instead, 'single malt' refers to a whisky that is produced by a single distillery using a single malted grain (usually barley) and distilled using a pot still.

Single cask whiskies, on the other hand, are drawn straight from one individual cask. This is whisky in its most authentic form; untouched, elemental, pure. Due to an almost infinite combination of factors, such as the cask's original contents, the unique character of its wood, and the temperature of the warehouse it is laid in, no two single cask whiskies are the same. This creates a dram that is truly inimitable and sought-after for its exclusivity.

One of the most magical elements of the whisky-making process is undoubtedly cask maturation. Experts believe that as much as 80% of a whisky's flavour may come from the very wood it was aged in. The cask is an intrinsic part of whisky creation, and the components of a single cask come together to create something totally unique.

Unlike normal bottlings, single cask whiskies are affected by just four things: the quality of the distillery's new-make spirit, the quality and type of wood it is matured in, the length of time for which it is matured, and the strength at which it is bottled. This means that each bottle is stamped with information on what year it was distilled and when it was bottled, making them an excellent historical archive and a whisky-looking glass into a distillery's processes from a particular era.

Single cask whiskies are also alluring thanks to their ability to showcase a side of a distillery that drinkers may otherwise not get the chance to explore. Focus on the flavours from an individual cask and less intervention from the whisky makers mean the end result is likely to taste different to the distillery's classic single malt, giving drinkers the opportunity to try something 'off the beaten path' from their favourite brands.

For collectors and whisky experts alike, single cask whiskies are an endlessly fascinating rabbit hole. The joy of single cask whiskies is the discovery of unique bottlings from a particular distillery, which may either be a quintessential expression of that distillery's style or a complete departure from it. As they sell, get poured out and sipped on, they become rarer and rarer by the dram.

At Cask and Bottle Co, we are lucky to have experts in the whisky field who know exactly which casks to pick. We also use a team of third-party whisky experts to sample all of our casks pre-bottling and write up an accurate description of their flavour profiles. So, whether you're a collector, a connoisseur, or simply looking to try something new and unique, explore the world of single cask whiskies – it's a journey you won't regret.
