METHOD OF PRODUCING BEER HAVING A TAILORED FLAVOUR PROFILE.

摘要

The present invention relates to a method of producing beer having a tailored flavour profile. More particularly, the invention provides a method of producing beer that comprises the successive steps of: a)fermenting a wort containing fermentable sugars with an active yeast to produce a beer containing 1-10 vol.% ethanol and further containing the beer flavour substances diacetyl; acetaldehyde;dimethyl sulfide;ethyl acetate; isoamyl acetate;ethyl valerate;ethyl hexanoate; iso-amyl alcohol and 2-methylbutan-1-ol; b)contacting the fermenting wort or the beer with porous adsorbent particles to selectively adsorb the beer flavour esters ethyl acetate, ethyl hexanoate, ethyl valerate and isoamyl acetate; c)separating the adsorbent particles containing the adsorbed beer flavour esters from the beer to produce a flavour adjusted beer containing 1-10 vol.% ethanol; d) desorbing at least a portion of the beer flavour esters from the separated adsorbent particles; and e)adding at least a fraction of the desorbed beer flavour esters to the flavour adjusted beer or to another beer, wherein the amount of beer flavour esters that is added to the flavour adjusted beer represents 5-95 wt.% of the amount of beer flavour esters that was removed from the beer by the adsorbent particles;.
