Bappir Bappir was a Sumerian twice-baked barley bread that was primarily used in ancient Mesopotamian beer brewing. Historical research done at Anchor Brewing Co. in 1989 (documented in Charlie Papazian's "Home Brewer's Companion" (ISBN  )) reconstructed a bread made from malted barley and barley flour with honey and water and baked until hard enough to store for long periods of time; the finished product was probably crumbled and mixed with water, malt and either dates or honey and allowed to ferment, producing a somewhat sweet brew. It seems to have been drunk with a straw in the manner that yerba mate is drunk now.
