Beer prodn. from wort concentrate - evaporated in two-stages to a stable powder for reconstitution to a pitching wort

摘要

The process for making beer by concg. a wort then subsequently reconstituting the conc. to its original moisture content, adding yeast and fermenting, is improved when the wort is concd. under vacuum at 40-60 degrees C to give a fluid wort conc. of 18-50% moisture; concg. further to a powdered conc. of 2-5% residual moisture which may be stored, and reconstituting by mixing the powdered conc. with water at 5-20 degrees C. The wort conc. does not darken on storage.
