A distinctive sourdough bread born from our collaboration with Anastasiou Brewery. Made with 30% spent grain — the precious remnant of malting — and wholegrain dinkel, ProZythenio brings together the deep, full flavor of beer with the vibrant acidity of natural sourdough. A dense crumb, crisp crust, and aromas of roasted grains — a bread that celebrates the power of fermentation and collaboration.
