Hario Technica Syphon 5 cups

This vacuum brewer can be used to make 3 cups of coffee
Fill the lower bowl with hot water and turn the heat on
Put ground coffee in the upper bowl and insert it over the lower bowl once the water starts boiling
The air expanded by heat will cause the all boiled water to rise in the upper bowl
Wait for a minute and then move the bowl away from the heat
Vacuum pressure will cause the brewed coffee to flow back into the lower bowl
That's all, you are now ready to serve a warm, aromatic, full-bodied and flavorful cup of coffee.
