They may not be able to control the weather at the The Dutch Trading Co (well, not yet), but they can certainly trick you into thinking it's warmer than it is by bringing enough good times to cure any winter doldrums.
Need proof? Here's Tropical Darkness, where they're basically pretending they're on a summer holiday while drinking all the beers that don't go down so well in warm weather.
So that means you'll see big beers from the likes of Struise, Almanac, Alesmith, Clown Shoes, De Molen and Evil Twin pouring. You might even find them serving imperial stouts in coconuts. And hosting a limbo contest.
Any summery attire – think Hawaiian/Baywatch/sailor's costumes – is heartily endorsed (though they do plead, for the love of all that is good in the world, you leave your mankinis at home).
And, befitting such an occasion, there will be prizes.
