Ghetto Siphon Coffee
Several months ago I read an article in New York Times about a $20,000 Japanese siphon bar at Blue Bottle Cafe in San Francisco.
A siphon bar or vacuum coffee maker uses vapor pressure & vacuum force to brew coffee. Many believes this would give coffee a cleaner, crisp, rich & smooth taste.
As a coffee aficionado myself, I believe the attraction to siphoned coffee is purely based on placebo effect.
To prove my point, I have built my own vacuum coffee maker for using only a moka pot & a glass salt shaker. Of course, you can also purchase a Bodum Santos for less than $100, but where is the fun in that?
My total cost was much lower than $20,000. Granted, I did not have fancy glass globe as the water reservoir.
After filling moka pot's boiler with water, I placed empty salt shaker over the top & coffee ground around it.
