Skógafoss is one of the most powerful and largest waterfalls in Iceland. To give this quadruple some extra power, it is infused with Þúfan. Þúfan is a refined version of the Brennivín ‘aquavit’ spirit, an artisanal liqueur from Iceland. Cumin, yarrow and reed grass are the spices you will find in the Þúfa Brennivín flavours. The soft texture is due to the fact that these herbs are all carefully picked by hand.
