great op: strung out, lots of questions, paranoid, demanding. spoken like a true jittering addict
so, one addict to another...
instant is a nasty, trashy buzz best kept for emergencies, portaledges and saving the good stuff from people who dont know any better.
filter is a quantum leap better than instant, and espresso that again from filter.
filter keeps the caffeine buzz of instant, with an appreciable gain in depth of quality. like comparing cheap champagne to the kind of wine you get as a gift.
espresso is the real thing. coffee how it should be. whereas instant depends on if the cups clean, and filter on the hardwear used, espresso depends on YOU.
are YOU up to it? to take the art of coffee in your own hands and be responsible for the outcome?
worth it? of course, its drugs. lack of quality is always what gives any drug a bad name.
go with quantity and expect erratic outcomes.
filter is not as good, can you live with that? personally i doubt people who can, but maybe its just me. coffee is very elitist. filter will do if its just about caffeine, but if its about coffee it wont.
no one pays to be served instant, and you pay for filter basicly because its necessary rent to get the free wifi and charge up on the caffeine.
espresso you pay for because its good.
the difference between 80 pound machines and 500 pound ones is in the seals, the filters, the quality of the workmanship and the pedigree. its like arcteryx to alpkit - it doesnt matter till you know the difference, then you suddenly see where you can go with it.
an expensive machine allows you more dexterity as the creator of your coffee - it puts you more in control. be aware, it takes years to draw out the nuances of a good machine. people dedicate their lives to the process.
does it taste different? yes it does, but like wine you need to develop the nose and palate. where it differs from wine is you get to experiment with the raw product yourself, finding that ideal blend from across several continents and all sorts of exploited peoples.
i say do it. maybe start with a cheaper end machine for a few years then get into the expensive stuff when youre ready, and by then you will appreciate it a bit more.
oh, and dont take any of this too seriously.
i am an addict afterall...
