So, final update. I tried it once (the Vietnamese style) and that's it. Now it's sitting on my counter, starring back every time I brew my morning coffee (with proper beans, of course) ...
Thanks for all the suggestion, I suppose trying coldbrew will be interesting. I also will try turkish style with additional sugar. And mybe Vietnamese after buying some condensed milk.
Wait, let me count... one in the morning, one during coffee break, one in the afternoon, and one before sleep... That's four...
