High gravity beer: what it is and when it is used
High gravity beer plant is usually chosen by big producers.
Technique is based on beer worth production, with a high plato grade, synonymous of higher alcohol content beer (compared to the common one).
High gravity beer plant is placed at the end of the line, in order to obtain the desired low alcoholic content through blending of the product from the fermenter/maturator’s outlet, deaerated water and carbon dioxide.
Even if it is a plant at the end of the line, high gravity conditions the brewhouse design, and many more important brewery aspects.
High gravity plant is indicated when marginal cost control per produced unit assumes a central value.
