Brewer's Yeast Extract

A tier

Brewer's yeast extract is made from spent or surplus brewing Saccharomyces, so a hop-bitter or beery note can ride along unless the wash was thorough. It is a thrift ingredient with a different nucleotide and flavour balance from a baker's-yeast extract grown for the purpose. Some traditional spreads and animal feeds (and a few food extracts) still start here. A good food-grade brewery extract has been de-bittered. If it tastes of IPA, the wash failed. Use baker's-yeast extract when you want a clean bouillon; use this when the brief is brewery upcycling and the flavour can carry a malt echo.
