Oklahoman brewery Prairie Artisan Ales was founded by two brothers with a passion for fine beers and a desire to share the love. To celebrate the brewery’s fourth birthday, the brothers brewed Prairie 4th Anniversary, a spice-infused Sour Ale. Once you have finished the puzzle on the label – not suitable for children or the easily offended – pop the top, and you’ll be rewarded with a beautiful orange body, and an attractive off-white head that conceal fruity, spicy notes and a lively yeast presence. The palate is a riot of sharp, fruity flavours, with grape and citrus featuring prominently. There is also an invigorating ginger note that combines with the sour character to give a crisp, dry finish.
