Free passes to “Brewing History Bus Tour” at upcoming book events

We’re giving away tickets to The Duluth Experience’s new “Brewing History Bus Tour” at the book events surrounding the release of Naturally Brewed, Naturally Better.
Fueled in part by history from Zenith City Press, the DE’s new tour “explores the stories of the Twin Ports pioneer breweries while sampling some of today’s brews along the way.” We’ll raffle off one pass—a $68 value—at our book launch at Clyde Iron Works this coming Thursday, September 20, at 7 p.m. as well as the other four events in October (event details here).
The tours begin in November, but there will be a special tour on October 14 with Zenith City Press publisher and Naturally Brewed coauthor Tony Dierckins tagging along for the ride, sharing more stories from the book.

    Tony, Possibly you may be aware of the original forming of the “Diamond Calk Horseshoe Company” (later Diamond Tool Company) by a West Duluth blacksmith, Swanson shortly after the turn of the 20th century. Most all the Duluth breweries delivered their kegs of beer with heavy team horse drawn wagons. Often these large work horses would fall on Duluth’s icey winter hills resulting in broken legs and sometimes injury to the teamster. West Duluth blacksmith Swanson became aware of this problem which resulted in his design and patent of the removable lug “calk” to his horseshoes, greatly reducing icey winter Duluth hill accidents. The lugs could easily be removed for summer use. His sales greatly increased with compatible forgeing machinery for the manufacture of the high quality Diamond brand of tools.

    That would be Otto Swanson. Yes, we write about Diamond Calk 7 Horseshoe in our book “Lost Duluth.”
