US-based New Belgium Brewing has released new beer 2017 Transatlantique Kriek and a Passionfruit Imperial IPA.

The 2017 Transatlantique Kriek has a sour taste due to the use of a 50/50 mixture of New Belgium Foeder-aged Golden Sour and Authentic Kriek Lambic from Oud Beersel brewery in Belgium.

New Belgium Brewing specialty brand manager Andrew Emerton said: “This year’s beer is particularly iconic because it’s 100% wood aged.

“Because of our process with this beer, we actually had the incredible honour of having Transatlantique Kriek at this year’s Toer de Geuze in Belgium, the premier sour beer event in the world.”

The Kriek Lambic process is followed at only a few breweries in Belgium, including Oud Beersel, which is New Belgium’s collaborative producer. In this process, authentic lambic is fermented and soured in oak barrels. Oud Beersel then matures the lambic on Polish cherries for months to produce the kriek, which is later sent from Belgium to New Belgium to be blended with an oak-aged sour golden.

The 2017 Transatlantique Kriek contains 6.5% alcohol-by-volume (ABV) and is available in 22oz bottles, as well as on draft. 

Under its Voodoo Ranger line, the Passionfruit Imperial IPA features tropical aromas and passionfruit flavours that are backed by Citra and Galaxy hops. It contains 8% ABV and is available in both 22oz. bottles and on draft and is offered for limited time.
