Can you age beer - and which really gains with time
Wine is aged, everyone knows that. But beer? Most people would not even think of it - beer is associated with a drink to be had right away, the fresher the better. And in the vast majority of cases that is true. There is, however, a fascinating group of beers that not only tolerate ageing but actually flourish with it, changing over years into deep, complex drinks closer to wine or whisky than to ordinary beer. It is a whole art for enthusiasts, called cellaring or ageing beer. Let us explain which beers suit it, why, and how to do it wisely.
Fresh versus aged
Let us start with a fundamental distinction, because without it you can do yourself harm. The vast majority of beers in the world are made to be drunk fresh and only lose with time. This is especially true of hoppy beers, like pilsners and IPAs, whose whole soul lies in the fleeting hop aroma - and that escapes and oxidises fastest. An old IPA is a sad shadow of itself, flat and cardboardy. Ageing makes sense only for a narrow group of beers with certain traits. Confusing these two categories is the most common beginner mistake: setting aside for years a beer that should have been drunk at once. The rule goes: cellar consciously and only the right styles.
The key is high alcohol
What decides that a beer suits ageing? The most important factor is high alcohol content. As in fortified wines, alcohol acts here as a natural preservative, protecting the beer from spoiling and giving it time to develop. As a practical rule, beers of at least 8 percent alcohol age well, and the stronger they are, the better they tolerate long maturation. Weak beers of low gravity have no structure or preservative in them to survive - they simply go stale. High alcohol is the entry ticket to the world of beer ageing, though not the only condition. The style and character of the drink matter too.
Which styles suit it
Let us get to specifics, because this is the most important question. The best candidates for ageing are strong, dark and dense beers. At the head stand imperial stouts (Russian imperial stouts) and barley wine, that is beer wine - both strong, malty and full. Baltic porters, strong old ales, Belgian strong ales like quadrupel age beautifully too, as do all beers aged in bourbon or wine barrels. A separate category is sour and wild beers (lambics, gueuze, Flanders), which thanks to their live microbial cultures can evolve over years. They are united by strength, intensity and complexity - traits that age deepens rather than destroys. We have written more about dark, strong styles separately.
What happens in the bottle
The most interesting thing is how beer changes over the years - it is a slow alchemy. Over time the sharp, alcoholic bite of a young, strong beer softens and smooths out, becoming velvety and integrated. Fruity esters transform into notes of dried fruit: raisins, plums, figs. Aromas associated with maturation appear - sherry, leather, tobacco, molasses, caramel, chocolate, nuts. The hop bitterness, if there was any, drops and gives way to malty depth. The result is a beer rounder, more complex and more contemplative than in its youth, though less fresh and lively. It is exactly the same logic that governs the maturation of wine or whisky - time trades freshness for depth and complexity.
How long to age
How much time to give the beer? It depends on the style and strength, but there are some frames. Most imperial stouts clearly gain after just a year of ageing, and the strongest of them, like barley wine and old ale, can be set aside for five or even ten years. You must remember, though, that it is not the case that longer is always better - every beer has its peak, after which it begins to decline. For many strong beers the optimal window is two or three years. A good idea is to buy a few bottles of the same beer and open one each year, to track for yourself when it reaches the peak of its form. It is the best learning and a real joy for the enthusiast.
How to store aged beer
The storage conditions decide success and are simple but absolute. Beer for ageing needs two things: cool and dark. Keep it at a steady, cool temperature - strong, dark beers age best at around 10-15 degrees, that is in a typical cellar. Avoid temperature swings, which speed up ageing and harm it. Protect the bottles from light, which, as we wrote, causes skunking - a dark cupboard or cellar is the ideal place. Keep beer bottles usually upright, so the yeast sediment settles to the bottom and contact with the cap is minimal. Stable, cool and dark conditions are all your beer collection needs to mature calmly.
Which beers not to age
As important as knowing what to set aside is knowing what never to age. Do not set aside hoppy beers - IPAs, APAs, pilsners, session lagers. Their virtue is fresh hops, which weaken every week, so time only harms them. Do not age wheat beers or delicate, light styles that live on freshness. Do not set aside ordinary, low-alcohol everyday beers - they have no structure to gain and will only go stale. The general rule: if a beer is pale, light, hoppy or refreshing, drink it as fresh as possible. Reserve ageing for strong, dark, malty behemoths. A mistake the other way - ageing a fresh beer - is simply a wasted drink and a disappointment.
Risk and surprises
It must honestly be said that ageing beer is an uncertain art fraught with risk. Not every bottle, even of the right style, will develop beautifully - sometimes a beer after years simply oxidises and goes stale instead of gaining depth. The outcome depends on the particular beer, the conditions and a little luck. It can happen that a favourite imperial stout after three years turns out worse than fresh. That is part of the fun, but also its cost. So never set aside the last bottle of something you love, hoping it will be better - ageing is an experiment, not a guarantee. It is best treated as a hobby and an adventure, not as a sure investment in better flavour.
How to start
Finally, practical advice for the beginner beer cellarer. Start simple: buy two or three bottles of the same strong imperial stout or barley wine. Drink one at once, to remember the taste of the young beer. Hide the rest in a cool, dark place and open them after a year and after two years, comparing with your note from the first bottle. It is the cheapest and most instructive way to feel on your own palate what time does. You need no special cellar or equipment - a cool, dark cupboard and patience are enough. After a few such experiments you will sense for yourself which beers are worth setting aside and which to drink at once.
