The Alaska Distillery in Wasilla just recently launched its Smoked  Salmon Flavored Vodka, about a year after the Seattle-based Black Rock  Spirits introduced a bacon-flavored vodka.  
"I think there was some madness and some drunkenness involved,  honestly," said Toby Foster, an Alaska Distillery partner and the one  charged with coming up with new flavors with Alaska themes.
   Foster and Scotti MacDonald, another partner, said the current  formula took 48 tries, and some of the first 47 attempts were downright  disgusting.
   "Definitely the first few times we had our heave bucket close by," MacDonald said. "It was pretty bad, and you know, greasy."
