The "furan" is certainly in the pot or in the coffee! The coffee tastes really good with this coffee percolator of "GRAEF". Had not thought that the coffee of "Aldi" such a delicious aroma brings forth. Have an "analog" Percolator "Ikea" for 20.-, and the taste is in no way at this Espressokocher zoom. The pouring works unfortunately very bad! Every time something goes wrong! Absolute disaster. Must screwing together the pot a bit "fumbling", but that's with any coffeepot this type the same. Nice big water tank, and the valve is mounted quite high, so I fully get a 400ml cup. 80.- Did the business paid. If the espresso machine can not buy again. However, the coffee tastes very good nonetheless. Can not recommend the espresso machine "GRAEF" unfortunately! Absolute "scrap" !!! Fehlkonstruktion !!!
