The Draught Beer ecosystem spans three logical layers. Upstream, agricultural suppliers deliver barley, hops, yeast, and water that form the brewing base. Midstream comprises breweries that transform these inputs into finished draught beer, alongside OEMs that produce kegs, taps, and refrigeration units, and technology firms that embed IoT monitoring and POS integration. Downstream, distributors move bulk product to hospitality venues, retailers, and ultimately consumers. Value is generated through recipe differentiation, dispensing quality, and service experience, while revenue is captured at each handoff from raw material to the glass.
