i need to know all the places yuo could purchase instant coffee during the early 1900s and i also need to know what people did before instant coffee thx best answer gets 10 points

From a very little bit of research, it seems that instant decaf was invented around 1903, but regular instant not until 1920. Back then towns still had a local general store, not a grocery or supermarket. And obviously no convenience stores. And general stores were independently owned so they all had different names.

Before that, coffee was brewed in a by putting the coffee on the stove-top or in the fireplace or over a camp fire. I didn’t look up when the percolator was invented. Hope I helped some.
