As an expert sommelier and brewer, I can confidently say that Angostura bitters are not traditionally barrel-aged. The original recipe for Angostura aromatic bitters, created by Dr. Johann Siegert in 1824, does not involve aging the bitters in barrels. Instead, the bitters are made by infusing a blend of herbs and spices in a neutral alcohol base.
However, in recent years, there has been a rise in the popularity of barrel-aged bitters. Some craft bitters producers have taken the traditional Angostura bitters recipe and aged it in barrels to add a unique flavor profile to the bitters. These barrel-aged versions of Angostura bitters can add depth and complexity to whiskey and bourbon cocktails.
The process of barrel-aging bitters involves placing the bitters mixture in barrels that have previously been used to age spirits such as whiskey or rum. The bitters are left to age in the barrels for a certain period of time, allowing them to absorb some of the flavors and characteristics of the wood and the previous contents of the barrel. This aging process can vary in length, ranging from a few weeks to several months.
The result of barrel-aging the bitters is a more robust and nuanced flavor profile. The wood imparts its own unique flavors, such as vanilla, caramel, and spice, while the previous spirits that were aged in the barrel can contribute additional depth and complexity. These barrel-aged Angostura bitters can enhance classic whiskey and bourbon cocktails like the Old Fashioned or Manhattan, adding a new dimension to these beloved drinks.
It's worth noting that while barrel-aged bitters can be a fantastic addition to cocktails, they may not be suitable for every drink. The added flavors and complexity of the barrel-aged bitters may overpower more delicate cocktails or those that require a lighter touch. It's always a good idea to experiment and find the right balance of flavors when using barrel-aged bitters.
While the original Angostura bitters recipe does not involve barrel aging, there are now barrel-aged versions of Angostura bitters available on the market. These barrel-aged bitters can bring a new level of depth and complexity to whiskey and bourbon cocktails, making them a great addition to any home bar. Whether you choose to stick with the classic Angostura bitters or try out a barrel-aged version, experimenting with different bitters can open up a world of flavor possibilities in your cocktails.
