Moose milk (not the alcoholic beverage!) is commercially farmed in Russia, but you won’t likely find it easily in the United States. Moose milk is what it sounds like - the milk from a lactating moose! It’s apparently high in butterfat (10%) and higher in some nutrients (iron, zinc, etc.) than cow milk. Meanwhile, the traditional Canadian cocktail is basically a spiked milkshake somewhat akin to eggnog.
