Whether it is bottled craft beer or freshly beaten craft beer, if it is left for a long time, it will appear stale. Craft beer staleness takes on different characteristics depending on the craft beer. So how should we judge? As long as everyone passes through these points, they can judge it.
Manifestations of craft beer staleness:
(1) Slightly stale
At this time, the craft beer will show a cardboard taste, the ester flavor will disappear, and the astringent bitter taste will be aggravated.
(2) Stale
At this time, craft beer will have a toasty taste, the body or texture of the wine will change, and there will be a pungent bitter taste.
(3) Very stale
At this time, the craft beer will have a honey-like taste, a decomposed bitter taste.
Craft beer staleness in relation to its type and type:
(1) Lager
Signs of sweetness, stale paper/cardboard and metal increase. However, the floral aroma and alcohol characteristics of craft beer have decreased, and they have become less like raga and more like al-ayr.
(2) Al
The malt characteristics will remain, but will be reduced, with sweet, dried fruity and cheese flavors and, in extreme cases, cat flavors. Craft beer can feel the ester aroma and taste is reduced.
(3) Stout
The oxidation of Stout craft beer can damage malt and caramel flavors, and may also have cheese flavors, as well as stale tastes.
(4) Strong craft beer
Strong craft beers are relatively stable in taste. There are no cardboard, leather and metallic flavors that are common in craft beers with lower concentrations. At the same time, the caramel, licorice and astringent taste will increase, and the alcohol taste will also change.
And craft beer will age and die with yeast cells, producing a salty, soy sauce or MSG taste.
