this plunger coffee treats us every morning with a velvety and delicious coffee !! for organic consumers: coffee is contained in the glass: no phthalates, bisphenol etc. you should know that it takes a coffee grinder as it must be coarsely ground, he infuses 4mn over time heating water (which does not boil if the coffee has a burning taste). for lovers of coffee and refined flavors in general, which take their time I highly recommend it. if not for the coffee time! It is an investment: + cafetiére mill, but that does not disappoint.
