What causes the bitter taste in beer?
Bitterness is one of the unique attributes of beer that distinguishes it from other beverages. The soft and pleasant bitterness stimulates the intriguing aroma and gives people a pleasant enjoyment.
The bitterness characteristic of beer comes from hops, and the mellow flavor comes from its aromatic resin.
Most of the beer we usually drink has a refreshing bitter taste, which is produced by hops in the beer ingredients. Hops are female flowers of a creeping plant. The petals contain tannins. The pollen contains hop oil and bitter resin. The hop oil gives the beer aroma, and the tannins and resin make the beer bitter.
In addition, there is a kind of sweet beer with a sweet taste. The production and sales are not large, mainly to meet the needs of people who do not drink. It is made by adding 4 to 6% syrup or a small amount of sweetener to cooked beer. This kind of wine has sweet taste, insignificant bitterness, low alcohol content and sufficient carbon dioxide gas; the foam is delicate and long-lasting, and is popular among women.
Internationally, the universal bitterness standard IBU is used to express bitterness. There is also an approximate standard for the bitterness range of each type of beer. Different beer IBUs have different impacts on oral taste buds.
