Is a great place to experiment with different varieties, brewing times and grinds. The important thing is that you can freshly grind the powder and the water not too hot (boiling) or cool (below 80 degrees), in between just about anything is possible. What you should consider, however, is that it takes quite a lot of coffee for one cup. Is it in the normal filter a lot of about 7- 9 grams per cup, has in the Aeropress a lot of 12 - 15 grams as proved necessary.
Compared to hand filters, the result is a much milder coffee, almost no bitterness, and the temperature of the coffee is due to the short brewing time and the subsequent pouring of the "coffee concentrate" with hot water higher than the hand filtering (I compare with the hand filters, because the my previous method for the manufacture of just one cup of coffee is). We come then to limit the Aero Press: Similar to well pad or capsule machines you can take the Aero press only 1 - Making 2 cups of coffee at once. The time that you need to prepare also corresponds approximately to the time it takes with a capsule or pod machine. For tea party or something similar but you should still have a "big" machine in the closet (I z. B. the Krups T8, also highly recommended). Aeropress coffee tastes but much better than the coffee capsule.
It cuts down on waste, in the description is even indicated how you can use the filter again. It has little cleaning effort, only the coffee grounds should be briefly rinsed bottom of the device.
In my opinion, therefore a prima replacement for a pad machine or a hand filter, "substitute" it is not true, because the Aero Press offers a lot more possibilities for variation.
