Landlord, I have used mocha pots for four years, both good and bad. I feel that as long as the technique is right, it will not have much impact on the taste. As for how much you want to add ... generally speaking, there is a graduation line in the middle of the powder can, and the wedding place is generally half of the powder can. If the concentration is normal, it is enough to add coffee powder there (I said gently compacted). If you like espresso, you can top it up. A good mocha pot has a reduction disk, but I seldom use that thing. As for how much to add, please adjust it according to your own taste and find a moderate amount.
