Gentle Boiling: a new dimension in wort preparation (Part 2)
Gentle Boiling, that is careful wort boiling at low steam pressure and downstream wort treatment using vacuum evaporation. Results presented in part 1 (BRAUWELT International No. 5, 2010, p. 304 – 307) related to downstream wort treatment using vacuum evaporation and to technical-technological results obtained on a commercial scale. In ongoing technological discussions with customers, it emerged on the basis of the very favourable results obtained in production of premium worts that it was worth considering whether gentle wort boiling with low steam pressures, and the associated low wort temperatures, could have an additional positive influence on production of top quality worts.
