Jax Brewing was founded with financial help of the Schorr family. Jax Brewing's founder, William Ostner was married to the daughter of Jacob Schorr of Schorr-Kolkschneider Brewing Company of St. Louis. At the time, the family owned breweries in St. Louis, New Orleans, Memphis, Louisville, Green Bay & Appleton, WI and Alton & Waterloo, IL.
I'm not sure of how it matches up with all of today's local craft breweries in size but it laid off 243 employees right after the passage of the Volstead Act. During prohibition, it employed 45 with a monthly payroll of $6,000, making near beer, ice cream and bottling root beer and ginger ale for the Charles Hires Company. His father in-law's brewery in St. Louis got hit with $25k in fines and shut down by prohibition agents.
From what I can tell, Jax Brewing's region was Florida, Georgia, South Carolina and North Carolina. At it's height, Jax Beer produced 100,348 barrels annually in 1943. 484,377 combined barrels were produced by all Florida breweries that year. It was around this time that they created the concept of the six-pack. By comparison, an FTU article last month mentioned that IAW is up to around 6,000 barrels annually.
The popularity of the aluminum can eventually did them in. The company was making a lot more money from cold storage (started doing this during prohibition) and decided to focus on that growing market instead of beer production. The old 130,000 square foot plant still stands in Durkeeville on West 16th Street. Here's a quote on canning from one of the founder's sons that I included in Reclaiming Jacksonville:
According to Jack Ostner, World War II was also to blame: "The boys got back from somewhere they hadn't been before, and that's when the nationals began to take over. Then cans came in and the national companies could absorb the cost of cans (the cans cost more than the product) by charging them off to freight."
