Diageo reports lower quarterly beer sales in Great Britain and Ireland

Diageo said on Thursday, November 5, that its beer business in Great Britain and Ireland declined in the July-to-September quarter, even as Guinness posted double-digit growth in Africa and in the German-speaking markets of Germany, Austria and Switzerland.

The British drinks group disclosed in its quarterly trading update that organic net sales of beer in Great Britain and Ireland fell at a low-single-digit rate from the same quarter in 2025. In the same statement, the company said Guinness grew at a double-digit rate in both Africa and the combined market of Germany, Austria and Switzerland. Across Europe, the Middle East and Africa as a whole, Diageo said beer net sales rose at a low-single-digit rate.

The figures point to a split picture for one of Diageo’s most important beer brands. Guinness has been expanding beyond its traditional base, but the company’s update showed pressure in two core markets where the broader beer portfolio moved lower. The distinction is important because the decline in Great Britain and Ireland covered Diageo’s beer sales overall, while the stronger growth in Africa and in Germany, Austria and Switzerland referred specifically to Guinness.

Diageo did not provide market-by-market sales amounts, profit figures or beer volumes for those regions in the update. The statement used growth bands rather than exact percentages, and the results were unaudited. As a result, the company’s disclosure does not show how many hectoliters were sold or whether changes in revenue were driven mainly by volume, price or product mix.

The performance matters because Guinness remains heavily tied to a small group of major markets. Diageo has said that Great Britain, Ireland and the United States accounted for 54% of Guinness’s global retail sales value in 2024. That concentration makes any weakness in its home and nearby markets significant, even when the brand is growing quickly elsewhere.

Diageo is a major player in global brewing, though beer is only part of its wider drinks business. According to BarthHaas, the company ranked 12th in the world by beer production in 2025, with 24.42 million hectoliters. Guinness is its best-known beer brand and one of the most visible parts of its portfolio, giving added weight to regional shifts in demand.

The company’s update suggests that Guinness continues to gain traction in markets where it has been investing in distribution and brand building. Africa has been one of the brand’s strongest growth areas for years, supported by established local positions in countries including Nigeria and Ghana. The double-digit increase in Germany, Austria and Switzerland also indicates continued momentum in continental Europe, where Guinness has been pushing further into bars, retail chains and newer consumer occasions.

At the same time, the decline in Great Britain and Ireland shows that gains abroad are not fully shielding Diageo from pressure in mature markets. Diageo did not break out the reasons for the drop in its beer sales there, and the update gave no detailed comment on consumer spending, pricing or competition in those countries. Without exact sales or volume data, it is not possible to determine how broad the weakness was across brands or whether Guinness itself underperformed in those markets.

The broader regional picture was more positive. By reporting low-single-digit beer growth across Europe, the Middle East and Africa, Diageo signaled that expansion in markets outside Great Britain and Ireland was enough to keep the wider regional beer business moving higher. That result, however, also underlines how uneven the quarter was: strong Guinness growth in selected regions offset weaker results in a key part of the company’s traditional base, rather than reflecting uniform momentum across the whole geography.

Because the company reported only organic net sales trends, the update also leaves open questions about the balance between pricing and underlying consumption. Organic sales figures strip out the effects of acquisitions, disposals and currency movements, making them useful for comparing operating performance. But in the absence of absolute revenue or volume numbers, investors and analysts cannot tell how much beer demand changed in physical terms in Great Britain, Ireland, Africa or the German-speaking markets.
