Heineken suffered a profits hangover in the first half of the year as miserable weather cooled drinkers' thirst for lager.
The Dutch brewing giant, which owns a range of brands including Foster's and Newcastle Brown Ale, saw beer sales volumes dip by nearly 10% in the UK.
Even the recent heatwave did little to boost its fortunes, with spending still subdued amid difficult economic conditions.
Operating profits in western Europe were down 9% on a like-for-like-basis though they were steady across the wider group amid better performances in markets such as Asia and central and eastern Europe.
Heineken also said it had seen encouraging early results from the launch of its "Radler" products - a mix of beer and fruit juice.
The drinks - which have lower alcohol content than beers and are seen as targeting women - were launched in 12 new markets in the period, meaning they are now sold by Heineken in 24 countries.
In the UK, the brewer launched Foster's Radler as well as several new flavours of its Bulmers cider, though it struggled with the wider performance of its product range.
"Against a backdrop of unseasonably poor weather and continued low consumer confidence, beer volume in the UK declined in the high-single digits, with cider volume declining in the mid-single digits," the group said.
However brands such as Heineken, Desperados and Bulmers posted strong volume growth, it added.
Revenues in western Europe dropped 5% on a like-for-like basis to 3.6 billion euros (£3.1 billion) on beer volumes down 8%. Operating profits in the region fell by 9% to 362 million euros (£309 million), compared to the same period in 2012.
Worldwide volumes declined by 3%, with like-for-like revenues down 1%. Net profit before one-off items was 679 million euros (£580 million), flat on a like-for-like basis as revenue per hectolitre increased 2%.
Chief executive Jean-Francois van Boxmeer said the brewer continued to operate in a "challenging trading environment" but that increasing focus on higher growth regions was delivering, with operating profit in developing markets up 7%.
Heineken last year took full control of Asia Pacific Breweries, maker of Tiger beer.
Mr van Boxmeer said an ongoing focus on costs had delivered 139 million euros (£119 million) of savings in the first half of the year. He was cautious about performance for the rest of 2013, despite the better summer.
"Although the volume trends have improved in July with the warm summer weather in Europe, economic conditions in several of our core markets continue to constrain consumer spending," he said.
