Siphon pot coffee boiler to enjoy the atmosphere
[features]
The main principle is that using the PV=nRT ideal gas equation, under a fixed volume, heating the steam pressure of boiling water, pressing boiling water into the upper layer to brew coffee through a glass tube, and then cooling the lower layer in a similar vacuum state to absorb the coffee already brewed in the upper layer, and filter the dregs with the filter paper in the middle. This kind of siphon coffee brewer is different from the general filter, its key point is that in order to make the coffee and boiling water can be completely mixed, it is necessary to use a bamboo spoon to stir in the boiling water of the coffee powder. You can enjoy the coffee while watching the extraction process, which is the charm of the rainbow tube. It can also be used as an ornament. It's just that compared with the dripping type, the operation is a little complicated.
[about apparatus]
It's troublesome in management, but I'll get better after I get used to it. Therefore, care should be taken not to break the glass. After use, the filter should be cleaned carefully and soaked in water. And keep it in the fridge.
[preparation before brewing]
After the boiling water at the bottom of the ● is completely boiled, the upper part is inserted. Insert too early to get the coffee out properly. ● stirs the boiling water and coffee powder properly in a short time. Spending too much time will muddy the coffee and lose its flavor.
[brewing method]
Add hot water to the coffee cup, and put more hot water in the pot than in the N cup.
First heat the pot until it boils.
Then insert the pot (when the water boils to make it rise).
When the water is not rising, remove the fire and stir in the pot to soak the coffee powder evenly into the water.
Stir about five times, move the fire into the heat, and the clock starts.
Time about 30 seconds, then move the fire away, stir up about five times, and then move the fire in (the clock is uninterrupted).
It takes a total of about a minute (stop the clock) to remove the fire and wipe off the pot with a semi-wet cloth (when the water drops immediately). When the water drops completely, go to the pot and move the pot into the fire.
After hearing the sound of three blisters, remove the fire and turn it off.
Pour out the cup with hot water and pour the coffee until it is eight minutes full.
Then add seasoning according to your personal preference. PS: the total time of Blue Mountain is about 50 seconds, and the other minute is about one minute. After a minute and a half, there will be more bitterness, thicker and sour, stirring for about a second. PS: the sixth step is to force the water away from the coffee powder, not to soak for too long, and drink other flavors PS: lazy, you can save the eighth step
