The full record
Krausening has its own catalogue entry with the detail this page summarises — causes, thresholds, related styles and evidence.
Krausening — Carbonate beer by adding actively fermenting wort rather than refined sugar — the traditional German method.
Beyond carbonation, the fresh yeast introduced also helps clean up diacetyl and acetaldehyde. It was the compliant way to condition beer under the Reinheitsgebot, which permitted no added sugar.
