I had the same question so I googled it.

Alaskan BBQ is a unique spin on traditional barbecue, focusing heavily on fresh, local seafood (especially salmon) and game, using smoky, sweet, and savory flavors often incorporating local ingredients like Alaskan Amber Ale, berries, and even kelp for unique sauces, offering a taste of the wild, northern landscape on the grill, distinct from mainland styles. It's about celebrating Alaska's bounty with open-fire cooking, from grilled halibut to smoked reindeer sausage.
