There were minor differences in the laws of earlier prophets.
For example Camel's meat was prohibited for consumption in earlier law, primarily due to scarcity of the animal or lower growth rate or maybe it was primary mode of transportation. Anyway whatever may be the reason it was not allowed to kill the animal and eat its meat.
In prophet Muhammad's sharia it is perfectly allowed to consume camel's meat. Maybe due to abundance of the animal and availability.
Furthermore dietry laws for jews are far more strict than in islam. For example they are not allowed to mix products of milk and with meat, poultry etc.
Consumption of wine is as old as advent of human civilization. Not all forms of its use is bad , as mentioned in holy quran. There are some benefits too. Like it keeps you warm in cold weather. So if people of Alaska consume liquor then it is their genuine and legitimate requirement. They do it keeping their bodies warm and in working condition.
So Hypothetically if some prophet was appointed in colder region, it is very much possible that liquor was not banned for those people. They consumed it for very reason staying well and fighting chilly weather conditions.
And any proof or reference to what you wrote is?
