During renovation, a cache of old bottles surfaced beneath the building, carrying a few clues about the people and businesses that came before us.
During demolition work at The Back Door, a group of old glass bottles was uncovered beneath the bar floor.
Cloudy, worn, and marked by years underground, they looked like ordinary debris at first. But the details told a different story.
Several bottles are made from aqua, pale green, and nearly clear glass, with thick walls and uneven surfaces. Their shapes vary, and some appear to have been formed by hand or in early molds. The narrow necks were likely made for corks or early crown caps rather than modern screw tops.
Those features place the bottles near a major shift in manufacturing, when hand-blown glass was gradually being replaced by machine-made bottles. That transition began around the turn of the twentieth century, and bottles from both methods often appeared side by side.
One bottle still carries part of a faded beverage label that may be connected to a Milwaukee brewery or bottler. The lettering is too damaged to identify, but in a city shaped by brewing, the possibility feels fitting.
Based on the bottle shapes, glass colors, neck finishes, and remaining label, the strongest estimate places most of the collection between 1900 and 1915. A reasonable overall range is 1890 to 1930, though a few pieces may date back to the 1870s or 1880s.
A closer look at the bottle bottoms, mold seams, lips, and embossed lettering may narrow the date or connect them to a specific Milwaukee company.
“ For now, they remain part evidence and part mystery. ”
The bottles have been brought back above ground and are now part of The Back Door’s story. Long before the cocktails and late-night conversations, other bottles passed through this building. We may never know who left them there, but the past has found its way back into the room.
Come see a few of the bottles on display, and raise a glass of your own at The Back Door.
