Fenrisian Ale

Fenrisian Ale, called Mjod in the Fenrisian Low Gothic dialect, is an extremely potent concotion distilled from the native plants of Fenris. Highly alcoholic and toxic, it is one of the very few beverages that can actually intoxicate an Astartes, managing to bypass their impressive bioengineered resistance to toxic substances. Space Wolves are fond of the drink, and consume large amounts of Mjod during their boisterous feasts, often competing against one another to determine who can drink the most Mjod before passing out.

History
Enjoying a hearty feast after a hard day's work is a time-honored tradition on dangerous Fenris, and the Vlyka Fenryka have kept this tradition alive, despite being transformed into superhuman Astartes. Their Primarch Leman Russ was as famous for his fIghting prowesses as he was for the quantities of meat and alcohol he could ingest, to the point he actually offered the Emperor an eating and drinking contest before calling for a duel when challenged. The Space Wolves as a whole enjoy drinking contests, and in general feats of feasting are held in regard next to feats on the battlefield.

Due to their bioengineered superior physique, it is normally impossible for an Astartes to get drunk. The combined effect of the Preomnor and Haemastamen is so efficient at breaking down and evacuating alcohol that an average Space Marine can fill both his stomachs with a strong alcohol like Sacra or Amasec and not become inebriated. Those Astartes outsides the Space Wolves that do drink alcohol occasionally do so because they enjoy the taste, or because a diplomatic situation warrants it.

The Space Wolves Mjod incorporates a natural toxin that temporarily neutralizes the Preomnor implant. This, combined to the very high alcohol grade of the Mjod allow the Space Wolves to get drunk. Even then, it require large amounts of the drink to affect them, and they will recover quickly. When sharing the drink with non-Astartes, the Space Wolves must make sure to add an anti-toxin to the drink, for it will otherwise prove fatal to a normal human.
