Here is my DD coffee maker. Sorry about the photo being sideways. It's an automatic KitchenAid siphon/vacuum type and makes delicious coffee without any bitterness.
Coffee Maker
Seems that the vacuum makers can’t be beat for good flavor.
I have a Sunbeam Vacuum Coffe Master that I don’t use often enough.
After seeing yours, I might drag mine out again
Currently, for various reasons, I limit myself to one cup of coffee a day, preferably before noon. I use K-Cups and a Keurig 2.0 brewer. IMHO the results are generally equal to fresh ground.
