The Crossroads of the Aether
The use of a vacuum siphon actually dates to the early Victorian Era and is still in use today. I thought this company made a reasonably ornate steampunk coffee maker, although it could use a bit more embellishment and gilding the lily, so to speak.
Here is a really good link about the history of coffee siphons http://baharris.org/coffee/History.htm. A coffee maker such as this could really enhance a steampunk coffee break.
