What Is Barrel Aging and Why Does It Matter?
November 22, 2023A Symphony of Time: How Aging in Oak Casks Transforms Wine
December 19, 2023At its core, making spirits involves several key steps, including distillers’ recipes, ingredients and sourcing, fermentation, aging, and barreling – each plays an essential part. Of these processes, spirits barreling stands out as an integral factor that imparts both flavors and textures into the finished product.
Charred oak barrels are essential in the process of making alcohol, adding flavor, color, texture, and specific aromas to its contents. These result from chemical interactions between wood and liquid, along with gradual evaporation of alcohol over time – known as angel’s share evaporation rate that differs for each batch and even between barrels within a warehouse.
Barrel-making is an intricate step of precision and adaptability; many barrel-making companies practice this art to perfection. Every barrel produced at Rocky Mountain Barrel Company not only serves functional purposes but is also an expression of craftsmanship. These barrels effortlessly navigate challenges, ranging from material shortages to changing climate conditions.
Care and craftsmanship go into each production stage, from grain to glass. That is why many of the world’s finest type of spirits come from small independent distillers who honor their ancestors’ hard work while carrying on their legacy of creating quality products for an appreciative customer base.
Traditional Barrel Ageing
Barrel aging has long been an accepted tradition that gives spirits their distinctive color and flavor profile. Depending on the product, environment, and barrel, the process may last anywhere from one week to several years.
Wood selection plays a critical role in barrel aged spirits process. Oak has traditionally been chosen due to its hardness, permeability, and aromatic qualities; however, other wood species have also been tested over the years. The oak barrel aged spirits offer a distinctive flavor and taste from the rest of the wooden barrels.
How the wood is dried – naturally or artificially in a kiln and for how long – has an enormous influence on the final product. Wood breaks down and extracts flavor from its lignin molecules during drying, creating phenols that contribute to giving spirits a distinctive smoky taste.
The Charred Oak Influence
The barrel plays an indispensable role in creating the unique character of spirits. Not only does charring impart color via tannins, but it also breaks down wood sugars into compounds such as furfural and 5-hydroxymethylfurfural that add sweetness as well as coconut flavors – creating what is known as the “red layer.”
Lignin molecules also break down to release vanillin, creating vanilla, cream soda, and graham cracker notes. Increased char levels can provide spicy or campfire aromas.
Charring was first adopted for various reasons, including extracting leftover flavors from a used barrel and saving time and money by shortening its finishing process. Charring dates back to 15th-century French cognac distillers who saw its benefits; additionally, it saves them time in finishing spirits more quickly than before.
Climate Impact
Spirit producers are immensely responsible for minimizing their environmental footprint, and consumers increasingly expect this of them. According to recent research, 90% of Gen Z consumers are willing to pay extra for products with sustainable credentials.
One method involves tracking and optimizing the temperature within warehouses where spirits are aged. In numerous distilleries worldwide, spirit makers utilize daily barometric pressure readings as a basis for their operations.
They repurpose distillery wastewater to reduce water wastes, turn leftover husks into fuel on site, fertilize barley fields with them, and use locally sourced ingredients to craft premium spirits that respect history while looking towards the future. Sustainability-minded brands deliver innovative barrel aged spirits made with care that you’d expect nothing less from them.
Importance of the Right Wooden Barrel
Whiskey, wine, and bourbon all owe their distinctive flavors to being stored in oak casks for extended periods. Oak has the inherent qualities necessary for shaping aromas and flavors in drinks from wood aging.
Barrels are crafted at cooperages by assembling oak staves without the use of glues or nails that could alter taste. These assembled barrels are then exposed to controlled heat for toasting, a process that concentrates wood sugars and imparts specific flavor characteristics.
Routine barrel inspections at Rocky Mountain Barrel Company help ensure they are in top shape, preventing leakage and water tightness between hoops and barrel stave connections. Furthermore, regular cleaning and sanitization are beneficial in eliminating flavors left from previous batches of wine or spirits stored therein.
Ocean Aging
One of the most intriguing methods of aging liquors is having them transported worldwide in barrels, known as ocean aging. This trend marks a new take on one of the oldest traditions in the luxury spirit trade. Ocean aging allows these spirits to visit at least five continents as they cross over multiple times the equator.
An ocean barrel-aging experience does not differ much from traditional distillery-aged barrels but does add another level of complexity to the final product. Sloshing of waves rocking it, hot tropical days and cool nights, changing temperatures causing expanding and contracting contents as temperatures fluctuate – all these factors shape its eventual outcome. When barrel aged spirits spent eight or nine months at sea, its results were astonishing and gave its spirit its unique taste and aroma that cannot be recreated elsewhere.
Conclusion
Like children growing and maturing, distilled spirits rise ever more refined when left resting in barrels for months or even years. This process, known as aging, is essential to many types of liquor, such as bourbons, whiskeys, tequilas, and rums. Aging helps eliminate harsher flavors while simultaneously developing distinct characteristics from the wood used as barrels. Depending on whether charred or uncharred wood is chosen and the duration of aging, the results can vary considerably.
Many brands of distilled liquors will note on their labels how long the liquid spent aging before being bottled. This practice is particularly common among whiskey and brandy producers; many varieties must age for at least a minimum amount of time before bottling; the higher quality the spirit, the longer its stay must last in its barrel. Behind every glass of spirits lies an extraordinary story of hard work and dedication by those responsible. Their success stems from an unwavering appreciation for heritage and hard labor.
