When it comes to whisky production, one term that often pops up is the “angel’s share”. You may have heard of it, but do you know exactly how much of the precious spirit is lost to the angels over time? Let’s delve into this fascinating topic and uncover the truth behind the angel’s share.
The Evaporation Phenomenon
At the very beginning of a whisky’s journey, while it rests in a cask, the angels are quick to claim their share. The angel’s share refers to the amount of whisky lost to evaporation during maturation. Initially, the angels take a generous portion of around 3.5% to 4% of the whisky each year.
Aging and Evaporation
As the whisky matures in the cask, the rate of evaporation gradually decreases. However, it is important to note that evaporation never stops completely. Instead, it continues to occur at a lower rate, taking a smaller share of the whisky as time goes on.
The Impact of Climate
The climatic conditions in which the whisky matures play a significant role in the evaporation process. In warmer climates, the angel’s share tends to be higher due to increased evaporation rates. Conversely, cooler climates experience less evaporation, resulting in a lower angel’s share.
The Magic of Wood
Wood, the material from which whisky casks are made, also contributes to the evaporation phenomenon. The porous nature of wood allows air to pass through, interacting with the whisky and facilitating evaporation. This interaction with the wood adds depth and complexity to the spirit, making the angel’s share an essential part of the maturation process.
The Angel’s Share Calculation
Calculating the exact angel’s share can be a complex task. It depends on various factors, such as the type of cask used, the age of the whisky, and the climate where it matures. However, as a general rule, around half of the spirit originally placed in the cask is lost to the angels over a typical maturation period of several years.
Distillery Strategies
Distilleries are well aware of the angel’s share and have devised strategies to minimize its impact. For example, some distilleries choose to store casks in warehouses with controlled humidity levels to reduce evaporation. Others may utilize smaller casks or cask finishes to shorten the maturation period and minimize losses.
The Value of the Angel’s Share
Although the angel’s share results in a loss of whisky, it is an integral part of the whisky-making journey. The evaporation process enhances the flavor profile of the remaining spirit, allowing it to develop unique characteristics that whisky enthusiasts appreciate. In a way, the angel’s share adds value to the final product.
Symbolic Significance
Beyond its practical implications, the angel’s share also holds symbolic significance. It represents a connection between the earthly realm and the heavens, as if the angels themselves are partaking in the whisky’s maturation process. This notion adds a touch of mystique and magic to the world of whisky.
Collectors’ Perspective
For whisky collectors, the angel’s share holds additional allure. Limited-edition or rare whiskies with a higher angel’s share are often perceived as more desirable. The notion that a significant portion of the whisky has been lost to the angels creates a sense of exclusivity and scarcity.
In Conclusion
The angel’s share refers to the amount of whisky lost to evaporation during maturation in the cask. While it initially accounts for a significant portion of the spirit, the percentage gradually decreases over time. Factors like climate and wood play a role in the evaporation process. Although distilleries aim to minimize losses, the angel’s share is an integral part of whisky production and adds character and value to the final product.
