Typically praised for the way it contributes aromas, flavors, and complexity, the method of alcohol getting older is mostly related to barrels. Synonymous with spirits akin to whiskey, rum, and brandy, producers of wine and beer additionally make use of the follow, albeit to a lesser extent.
Past prevalence — and certainly the usage of barrels — one thing else units aside the getting older of spirits and that of wine and beer. Specifically that when spirits discover their last resting and serving vessel (bottles), their evolution and improvement is all however full. However for wine and beer, a subsequent stage of getting older awaits — bringing with it the event of numerous new aromas and flavors (fascinating and in any other case). To raised perceive why that is the case, VinePair spoke with David Keck, grasp sommelier and winemaker at Stella14.
Whether or not or not alcohol continues to age in bottle depends upon a number of components, most significantly the method wherein the beverage was produced and the alcohol content material.

Within the case of wine and beer, alcohol manufacturing happens by means of fermentation –– a course of throughout which yeasts convert sugars into alcohol and different natural taste compounds, together with esters. Since yeast can solely ferment a lot earlier than the alcohol ranges develop into dangerous, fermentation in wine and beer yields a product with a comparatively low alcohol content material. This, Keck notes, permits the natural compounds created throughout fermentation to additional develop (“age”) as soon as bottled.
This may yield each constructive and damaging outcomes, relying on whether or not the wine or beer was produced with the intention to age in bottle, and whether or not or not they frolicked in oak earlier than bottling. “Preliminary barrel getting older of beer permits new esters and ethers to type,” Keck says. With extra natural compounds, these beers proceed to develop in bottle, forming new, advanced flavors akin to tobacco, vanilla, and dried fruits.
Spirits, however, are produced first by means of fermentation after which distillation, which delivers a product with the next alcohol degree than that of fermentation alone. “This basically acts as a preservative for the liquid and reduces the chemical reactions and prevalence of additional modifications as soon as it’s been bottled,” Keck says.
The position biochemistry performs throughout maturation is distinguished however, as Keck explains, different components together with the properties of the bottles are additionally necessary. “Darker bottles are usually greatest for getting older due to the results of gentle strike, which may enhance the prevalence of chemical modifications and degrade the liquid inside,” Keck says. Because of this, wines and beers supposed for getting older must be saved in a darkish and temperature-regulated location, like a cellar or wine fridge versus counter tops and cabinets. Quite the opposite, spirits are sometimes packaged in clear bottles as injury from gentle publicity is much less of a menace, and could be saved with out danger on bar carts and counters.
