Diageo has raised the average price of its per case price in supermarkets, drug stores and liquor stores by 2.1%, in the 26 weeks ended June 19, according to a story in today's Wall Street Journal.

The Journal quoted figures from tracker AC Nielsen, which it said were obtained from a AC Nielsen client.

The report said Diageo began raising wholesale prices on at least 19 of its top 25 brands, including Smirnoff, Baileys Original Irish Cream and Captain Morgan Original Spiced rum, according to Impact Databank's 2004 Annual Spirits Study.

However, the Journal suggested that the price rises may be hurting volume growth. ACNielsen data, it said, showed that Diageo's volume in the distribution outlets it monitors rose only 0.1% in the first half of this year, below the 1.7% growth rate recorded for the distilled-spirits category overall.
