The main fermentation driver in this culture is a Belgian saison strain. Beginning stages of fermentation produce classic bubblegum clove phenols.

The unique Brett character will start expressing within the first six weeks. Eventually pushing big tropical fruit and pineapple Brett character more than typical barnyard. With additional aging the pineapple character will become even more pronounced.
