I work in supply chain and logistics. Came across this interesting article around Bulk transport of beer/wine and spirits. Thought I'd share here. The idea of a tanker full of Guinness excites and scares me.... https://www.freightwaves.com/news/bulk-booze-by-sea-part-1-the-past
Interesting article. Thanks for sharing. When I visited the Guinness Storehouse in Dublin the most interesting part of the tour to me was a small section about the history of various Guinness-owned shipping technologies dedicated to beer going back nearly to the start of the company, including custom sailboats, tanker ships, rail cars, delivery trucks, etc. It's pretty clear that a major reason Guinness was successful for over 200 years was their constant willingness to adopt the latest transportation [and other] technologies.
I'm looking forward to the 2nd part being published. Seems to deal more with modern package sized transport. Many (most?) does NOT go refrigerated and can/does spend days in a trailer in a yard etc. I used to work for a carrier that did provide such logistics for beer and wine companies.
Starting around 1979, Anheuser-Busch imported Würzburger Hofbräu in bulk and bottled it at their Newark, NJ brewery (just a few miles from the docks). This was a few years after Miller took over the importation of Löwenbräu and then got a license to brew it in the US (with some notable recipe changes). The illustration in the ads at the time did take some artist license, but you get the idea. But, as noted in the OP, Guinness and Pilsner Urquell have been doing it for decades. In the US in the 90s, Anheuser-Busch complained that all Coors' beer wasn't brewed with "Rocky Mountain Water" because they shipped high gravity beer to Virginia and added local (Appalachian Mountain?) water to the beer. Coors counter-claimed that AB also made use of High Gravity brewing. "Yeah," AB replied, "but we do it in at the same brewery the beer was brewed at!" A few years back, F X Matt's canning line building had a fire and IIRC they shipped some beer in bulk to Genesee for canning.
