Title: PROCESS FOR ISOMERIZTION OF CONSTITUENTS OF A HOPS SUBSTRATE IN A BEER PREPARATION METHOD, CORRESPONDING APPARATUS AND USE OF THE ISOMERISATE
Abstract:
The invention relates to a process for isomerization of constituents of a hops substrate (H) in a beer preparation method comprising generation and thermal treatment of a wort (W). The isomerization takes place in an isomerization substrate (I) at a temperature between 15°C below and 2°C below a maximum temperature attained by the wort (W) during the thermal treatment of same in the beer preparation method. The isomerization time (tl) is 20 to 50 min longer than a time (tK) for thermal treatment of the wort (W) in the beer preparation method. The invention further relates to a corresponding use and apparatus.
