Instant coffee is revolting shite. I only drink the real stuff, you'd have to pay me to drink instant, or I'd have to be totally drained of energy, feeling like shit, not at all overloaded and in blistering, freezing howling cold before I drank that crap.
I need to get a new cafetiere...atm I have to brew it up in a cup from ground real coffee and then pull it through a fritted buchner funnel with filter paper with a vacuum pump into a clean round-bottom flask and then decant the coffee into the cup I brewed it in, after washing out the grounds. Given its just coffee alternately I could just use suction by mouth through rubber tubing attached to the vacuum hose barb, but that would take too long and be a pain in the ass. I like tea more myself. Especially white tea, made with lemon balm infusion instead of water, and with a bit of honey in place of sugar to sweeten it.
