Gentle Boiling: a new dimension in wort preparation (Part 1)
Gentle Boiling is the long-term systematic development, combining vacuum evaporation technology and low vapour pressure boiling, with vapour pressure in the wort copper during boiling operated at ≤ 0.8 bar g. This system has become established in the brewing industry since Ziemann Ludwigsburg launched it in 2000. This first part of a two-part publication deals with technology of vacuum evaporation. Part 2 will cover the new generation of internal boilers and their influence on the boiling process in modern breweries.
