Just in time for summer, Euroboozer is proud to announce the return of its hugely popular Stiegl 'Summer of Radler' cocktail competition, now in its sixth year and bigger than ever. For the first time, the contest is open not only to bartenders and mixologists, but also to the general public across the UK. Entries are now open, inviting beer lovers and budding mixologists alike to create their own unique cocktail using either Stiegl Grapefruit Radler or Stiegl Raspberry Radler. The winning entry will take home a £1,000 cash prize and a year's supply of Stiegl Radler. The competition culminates in a live final on Thursday 17th July, hosted on the rooftop terrace of Boundary London, where the final five cocktails will be tasted by a panel of expert judges. Renowned for producing some of the most eminently refreshing beers on the market, Stiegl mixes its iconic Goldbräu lager with homemade grapefruit soda for the Grapefruit Radler and raspberry lemonade for the Raspberry Radler. Both are delicious on their own, but also make excellent bases for seasonal beer cocktails. How to Enter To take part, entrants simply need to complete a short application form via the Euroboozer website, providing a recipe, method, and a photo of their cocktail, which must prominently feature a can of Stiegl Grapefruit Radler or Stiegl Raspberry Radler. The deadline for entries is Friday 27th June 2025. A panel will shortlist a minimum of 20 standout entries, which will then go to a public vote on social media. The five most popular cocktails will earn a spot in the live final. Martyn Railton, MD of Euroboozer, says: "Each year we're blown away by the creativity on show in the Summer of Radler competition. Opening it up to the public for 2025 felt like the natural next step. Whether you're a pro bartender or a home cocktail enthusiast, we want to see what you can create using Stiegl Grapefruit or Raspberry Radler. They're both delicious on their own, but also incredibly versatile cocktail bases." Quick Competition Summary:

About Stiegl
First mentioned in written records on 16th June 1492, Stiegl Brauerei in Salzburg, Austria, grew out of a popular beer-making guesthouse called the 'Bräuhaus an der Gstätten'. Over the past 531 years, Stiegl has seen immense joy and celebrations but also fires, war and economic turmoil. The brewery persevered, however, and has managed to remain strong, playing a huge role in both Salzburg and Austria's culture and history. Even Wolfgang Amadeus Mozart was known to be a fan of Stiegl's beers during the 18th century.
Today the brewery is best-known for its multi award-winning Stiegl Goldbräu beer, with Stiegl utilising a wealth of brewing experience combined with some of the most high-tech brewing equipment and processes in Europe. The brewery also benefits from the finest Austrian raw materials sourced from local farmers (some of which are cultivated in the brewery's own fields), plus Alpine Spring Water from Salzburg's house mountain, the Untersberg.
About Euroboozer
Started from the back of an old VW Vento in 2003, Euroboozer was set up by beer lover Martyn Railton, initially importing Austrian brands Stiegl, Schremser and Hirter. The company soon branched out across the Atlantic to bring some of the finest US craft brewers to the UK. 20 years on, the VW Vento has gone to be replaced with offices and a warehouse in Hertfordshire with a fleet of trucks delivering all over the country.
Euroboozer now supplies some of the finest food and beverage establishments in the country and their brands still include Austria's Stiegl, Schremser and Hirter, plus Madrid's Cervecera Peninsula, Munich's Giesinger Bräu, BlakStoc cider from Austria, and beers from leading British breweries such as DEYA, London Brewing Company, Rooster's, Siren and Verdant, which are mainstays in almost all of the UK's best craft beer bars and bottle shops.
