The recommended use-by date indicated on the beer packaging is the date until which the beer retains its optimal organoleptic characteristics. Some beers taste better for a short time after their production. They usually have to be consumed within a few months from the date of production to maintain their freshness. On the contrary, some beers can mature and improve over time, so they are stored for months or even years, which contributes to the development of new aromas and flavours.
