What is the history of the vacuum brewer?
The first reliable working vacuum brewing devices that were sold to the public showed up in France around 1840. They were patented then manufactured by Marie Fanny Amelne Massot of Lyons (aka Mme. Vassieux on her patents). From that point on, people tried different methods to hone, refine, and improve on these original designs. But even today, you can find vacuum brewers that are faithful to Mme. Vassieux’s original design and prototypes. While Mme Vassieux is often credited with inventing and manufacturing the original vacuum brewer, this is under some dispute. Some proof exists (reference Bramah’s book) that the vacuum brewing process was originally patented and invented in Berlin, some 10+ years before. Further, other inventors during the 1930s worked on a vacuum and steam principle to extract liquid coffee from grinds. But Mme. Vassieux stands out as having the most accurate and earliest patents on record, coupled with actual production models of her designs, which exist to this da
