In 1914, the Sonoma Vista Land Company, Harvey Toy, President, advertised in the San Francisco Examiner for a train excursion to Boyes Hot Springs:
“home sites $195 and up” and…”Boyes Springs mineral water served free on the grounds.”
Sonoma Vista was subdivision on the west side of Sonoma Creek, south of Boyes Blvd.
In January of 1918 the Index Tribune stated that “The bottling works of the now famed Boyes Springs Mineral Water has been put in the charge of Fred J. Hansen, popular musician and poultry man.” (A talented guy, apparently!) And “The management of the mineral water concern is no small matter as $25,000 worth of water was bottled and marketed last season.”
By 1925, the concern was managed by one H. Peterson, according to the IT. “Physician recommend the use of this water as a corrective for stomach and related troubles…Try a case and enthuse more and more over Boyes Springs,” the reporter stated, severely blurring the line between news and advertising.
Baseball players also enjoyed it, according to the Oakland Tribune in 1947:
The bottling plant, as shown on the County Recorder’s map of the Hotel Grounds subdivision, was adjacent to the Bath House near Boyes Blvd.

The building survived and has gone through a number of incarnations.

Hello! This is all super neat to learn as I grew up in Boyes Hot Springs, off San Gabriel dr. My grandma grew up in Sonoma and told my stories about stuff, she has one of those old bottles too. My grandpa was the artist who laid the blue tiles on the other side of that wall thing sometime in the early 2000’s, I remember seeing him work on it once as a young kid. His name was Micheal. I’ll have to come by and see it as an adult.
