I don’t think making your own booze was very common on Norwegian ships, at least when I sailed on them. (1960s) since you could buy the real thing reasonably cheap from the sloop chest.
The only time I can remember of “on board production” was on “Laybarge 200” of McDermott in the early 1980s, where we found a stiil and some ready “product” in the Mechanic*s work shop.
No wonder, since the crew worked 56 days on/28 days off on a “dry ship” and all offshore.
