Yes, some beers can improve with age, but cellaring beer provides no guarantee that the beer will be any better than when it was fresh. True, the volatile compounds, like hop aroma, that make up flavors and aromas change when beer is aged.
Hereof, how do you store beer for aging?
Wines are still aged on their side, but beer should be stored upright. You also want to have ample shelf space for the number of bottles you plan to cellar, as it’s much easier to store the beers in an organized manner with the right amount of space. You can separate your collection by ABV, by beer style or by brewery.
