Diageo

Diageo's heritage runs centuries deep. Arthur Guinness signed a 9,000-year lease on St. James's Gate Brewery in Dublin in 1759 for an annual rent of £45, betting that his dry Irish stout would find a market in a city that ran on porter and ale. John Walker, a grocer's son in Kilmarnock, Scotland, began blending Scotch whiskies in the 1820s to smooth out the inconsistencies of single malts — creating Johnnie Walker, which would become the world's best-selling blended Scotch. Both brands grew independently for over a century before the corporate consolidations of the 20th century began drawing them together.

Diageo was formed in December 1997 through the all-share merger of Guinness plc and Grand Metropolitan plc — one of the largest UK corporate mergers of the decade. Guinness brought Johnnie Walker, Guinness stout, and a portfolio of Scotch whiskies including Lagavulin, Talisker, and Cragganmore. Grand Metropolitan brought Smirnoff vodka, Bailey's Irish Cream, and the Pillsbury food business. The name Diageo was derived from the Latin "dia" (every day) and the Greek "geo" (world) — "across the world, every day." The food businesses (Pillsbury, Burger King, which Grand Met had briefly owned) were eventually divested, leaving Diageo as a pure-play spirits and beer company.

Diageo systematically built the world's broadest premium spirits portfolio through acquisitions and partnerships. The Seagram spirits portfolio — acquired in 2001 — added Captain Morgan rum and additional whisky brands. Don Julio tequila gave Diageo a premium Mexican agave presence as the tequila category accelerated. In 2013, Cîroc vodka — marketed in partnership with Sean Combs (Diddy) — became a case study in celebrity-driven brand building in urban markets. The company's acquisition strategy consistently targeted brands with authentic heritage that were under-distributed globally, then deployed Diageo's 180-country distribution network to build them internationally.

Casamigos was created in 2013 by George Clooney, Rande Gerber, and Mike Meldman — not as a business, but as a personal project. Clooney and Gerber owned neighbouring properties in Mexico's Casamigos ("house of friends") and spent years testing tequila recipes with their distillery to make a smoother spirit for their personal use. Their distiller eventually told them they were ordering 1,000 bottles a year and needed a commercial licence. They launched publicly in 2013. Within four years it had become the fastest-growing super-premium tequila in the United States. In 2017, Diageo acquired Casamigos for $700 million upfront with a further $300 million performance earn-out — up to $1 billion total. It reached 3.2 million cases under Diageo's global distribution.

Diageo reported revenue of approximately $20.3 billion (or £16-17 billion) for fiscal year 2024, selling brands in nearly 180 countries. The portfolio included Johnnie Walker, Crown Royal, Buchanan's, J&B (whiskies); Smirnoff, Cîroc, Ketel One (vodkas); Captain Morgan (rum); Baileys (liqueur); Don Julio, Casamigos (tequila); Tanqueray (gin); and Guinness (beer). The company faced headwinds from weak organic sales growth driven by post-COVID spirits normalisation in the United States and Latin America. The tequila boom — which had driven extraordinary growth at Don Julio and Casamigos — showed signs of maturation. Diageo maintained its position as the world's most powerful collection of spirits brands.
