The Angel's Share: Is Grain Alcohol The Answer?

The angel's share is a term used in the whiskey industry to refer to the portion of whiskey lost to evaporation during the maturation process. Whiskey is typically aged in wooden barrels, which can be made from oak. Over time, some of the alcohol seeps through the grain of the oak staves and evaporates, becoming the angel's share. The amount of whiskey lost to the angel's share depends on various factors such as the length of the maturation period, the climate, and the microclimate. The angel's share contributes to the complexity and depth of flavour in the remaining whiskey, as the evaporation allows for intricate chemical interactions between the liquid and the wood. While the angel's share is an unavoidable part of the whiskey-making process, it is considered a hassle by distillers, who have employed innovative techniques to minimise its impact.

The angel's share is the alcohol lost to evaporation during the maturation process

The Angel's Share is a term used in the production of whiskey and other spirits to refer to the alcohol lost to evaporation during the maturation process. This phenomenon occurs as the cask breathes, and the alcohol seeps through the grain of the oak staves, evaporating into the air. The amount of alcohol lost to the Angel's Share depends on several factors, including the length of time the spirit is aged, the type of wood used in the barrels, temperature and humidity fluctuations, and the climate of the production location.

The Angel's Share typically ranges from 2-5% per year per barrel, but it can be higher in warmer and more humid climates, such as Kentucky, where the loss can reach upwards of 5% per year. In contrast, colder climates like the Scottish Highlands may experience lower rates of evaporation, with an annual loss of about 2%. The type of wood used for the barrels also plays a role, with highly porous wood contributing to more liquid loss.

The Angel's Share is an unavoidable aspect of whiskey production, and it has both positive and negative impacts. On the one hand, it contributes to the complexity and depth of flavour in the whiskey by intensifying the concentration of flavours within the cask. This maturation process results in a smoother and more palatable whiskey. On the other hand, the loss of volume due to evaporation can be significant, especially for whiskeys aged for many years, driving up the price of aged whiskey.

Whiskey producers take the Angel's Share into account when planning their production to mitigate losses. They use various techniques, such as climate-controlled maturation warehouses and advanced cask management practices, to minimise evaporation rates and maintain optimal conditions for the maturing whiskey. However, no distillery can completely eliminate the Angel's Share, and the loss to the angels remains an accepted part of the whiskey-making process.

The evaporation rate depends on the climate, with warmer climates leading to higher evaporation rates

The "Angel's Share" refers to the portion of whisky lost to evaporation during the ageing process. Whisky is stored in wooden barrels, and over time, some alcohol seeps through the grain of the oak staves and evaporates into the air. The evaporation rate depends on several factors, and climate plays a significant role. Warmer climates lead to higher evaporation rates.

Whisky aged in cooler climates, such as Scotland, loses around 2-3% annually to the Angel's Share. In contrast, hotter destinations like Texas or Kentucky can experience an annual loss of over 5%. The difference in temperature affects the rate of evaporation, with higher temperatures resulting in increased evaporation. This is due to the decreased energy required for evaporation at higher temperatures.

Microclimates can also influence the Angel's Share. Even distilleries located close to each other may experience different evaporation rates due to slight variations in temperature, humidity, and other meteorological factors. Additionally, the length of time whisky is aged contributes to the Angel's Share. Longer maturation periods result in greater losses to evaporation.

To mitigate evaporation losses, some distilleries use climate-controlled maturation warehouses to regulate temperature and humidity. These warehouses help reduce evaporation rates by maintaining cooler temperatures and managing humidity levels. However, no distillery can completely eliminate the Angel's Share, and the evaporation contributes to the whisky's depth of flavour. As alcohol evaporates, the concentration of flavours within the cask intensifies, creating nuanced interactions that shape the final product.

The impact of climate on evaporation rates is not limited to whisky ageing. Climate change, for example, is expected to increase global lake evaporation, with potential consequences for water resources and precipitation patterns. Regional factors, such as snowmelt and solar radiation, also influence evaporation rates, highlighting the complex relationship between climate and evaporation.

The angel's share is an unavoidable circumstance that helps create a smoother, more palatable whiskey

The "angel's share" is a term used in whiskey production to describe the evaporation of alcohol during the ageing process. This phenomenon has occurred since whiskey first appeared over a thousand years ago in Ireland and Scotland. Whiskey is typically aged in wooden barrels, which can be made from oak. Over time, some of the alcohol seeps through the grain of the wood and evaporates into the air. This evaporation is what is known as the angel's share.

The amount of whiskey lost to the angel's share depends on several factors, including the length of time the whiskey is aged, the type of wood used in the barrels, temperature and humidity fluctuations, and the type of grains used. On average, whiskey producers estimate that the angel's share of alcohol lost annually is around two percent per barrel. However, this can vary depending on the specific conditions in which the whiskey is aged. For example, in colder climates like Scotland, the rates can be as low as two percent of the total barrel volume per year, while in hotter and more humid climates like Kentucky, the loss can be as high as five percent.

The angel's share is an unavoidable circumstance in whiskey production. While it may seem like a loss, it actually plays a crucial role in creating a smoother, more palatable whiskey. As the alcohol evaporates, the concentration of flavours within the cask intensifies, allowing for intricate chemical interactions that shape the final product. The evaporation of alcohol helps to reduce the percentage of alcohol in the whiskey, making it more mellow and easier to drink. Additionally, the interaction between the remaining liquid and the wood lends subtle nuances of vanilla, oak, and spices that enhance the flavour profile of the whiskey.

Whiskey distillers take the angel's share into account when planning their production. They can calculate and predict the expected loss due to the angel's share and adjust their production quantities accordingly. While some techniques have been employed to minimise the impact of the angel's share, such as climate-controlled maturation warehouses, no distillery has been able to eliminate it entirely. The angel's share is a unique aspect of whiskey production that contributes to the complexity and depth of flavour in the final product.

Whiskey makers have tried to minimise the angel's share through various methods, such as plastic wrap

The "angel's share" is a term used to refer to the portion of whiskey that is lost to evaporation during the maturation process. This phenomenon occurs when whiskey is stored in wooden barrels to age, and the alcohol seeps through the grain of the oak staves and evaporates into the air. While this loss may seem unfortunate, it is precisely what contributes to the complexity and depth of flavour in the whiskey. As the concentration of flavours within the remaining liquid intensifies, intricate chemical interactions shape the final product, lending subtle nuances of vanilla, oak, and spices.

Whiskey makers have employed various methods to minimise the angel's share and protect their precious inventory. One such method is the use of plastic wrap or cling film to cover the barrels. The idea is that the plastic wrap will create a barrier, preventing the alcohol from evaporating through the wood of the barrel. However, some people have questioned the effectiveness of this method, suggesting that the angel's share may simply become trapped between the plastic and the barrel, or that the wood may reabsorb it.

Another strategy to mitigate losses is to collect and store the evaporated alcohol, known as the "dew," either for use in the next batch or to be added back into the barrel at a later stage. Additionally, whiskey makers have explored the use of climate-controlled maturation warehouses to regulate temperature and humidity, which can significantly reduce evaporation rates. By maintaining cooler and more consistent temperatures, the rate of evaporation can be slowed, preserving more of the whiskey.

While some methods aim to directly prevent evaporation, others focus on predicting and managing the angel's share. Whiskey distilleries often employ master whiskey makers to regularly test and monitor the loss and flavour profile of their whiskey. Through careful calculations, they can anticipate the expected angel's share loss over time and adjust their production quantities accordingly. For example, if a distillery needs 1,000 cases of whiskey in five years and expects a loss of 5% per year due to the angel's share, they will need to produce 25% more to fulfil their target.

Although whiskey makers have found ways to minimise and manage the angel's share, it is important to recognise that no distillery can completely eliminate this loss. The angel's share is an inherent part of the whiskey maturation process, and even the most innovative techniques can only reduce its impact rather than eliminate it entirely.

The angel's share is an ethereal phenomenon with symbolic importance, representing the distiller's sacrifice

The Angel's Share is a phenomenon in whiskey production that has occurred since the spirit first appeared in Ireland and Scotland over a thousand years ago. The term refers to the portion of whiskey lost to evaporation during the maturation process. Whiskey is unable to take on its name until it has been matured in a cask for a certain period. The evaporation of alcohol during this process is what is known as the Angel's Share.

The amount of whiskey lost to the Angel's Share depends on several factors, including the length of time the whiskey is aged, the type of wood used in the barrels, temperature and humidity fluctuations, and the type of grains used. The evaporation rate can be as low as 2% of the total barrel volume per year in cold conditions like the Scottish Highlands, but in hotter and more humid climates like Kentucky, where bourbon is often made, the loss can be as high as 5%.

Whiskey production begins with the selection of grains for the mash bill, which varies depending on the type of whiskey. The grains are then mashed or malted, releasing sugars. During fermentation, the mash is exposed to yeast, which consumes the sugars in the grain mash and produces alcohol as a byproduct. The mixture is then distilled and poured into wooden barrels to age, where the Angel's Share phenomenon occurs.
