From the brewery:

Our classic export-strength brown porter is brewed with a carefully selected blend of Simpsons double-roasted crystal, red rye crystal, and amber malts, then conditioned on 150kg of Tunisian Deglet Nour date syrup. Fermentation with kveik yeast enhances the beer with additional dark-fruit character. The interplay of malt, yeast, and fruit creates layered notes of rich, dark fruit, resulting in a porter that is complex yet highly drinkable.
