I have been an espresso only person for about 10 years. Started after we spent 2 weeks in of all places Venezuela where there is cheap espresso in many many places because there are so many Italian immigrants. Plus they produce coffee as well so after 2 weeks of daily (several daily) versions of espresso I bought a machine for the home when we got back from that holiday.

Within a year I had upgraded and have upgraded again (Sylvia (espresso) and Rocky (grinder) now for those who follow this stuff).

Beans are key. There is a commercial boutique roaster (they sell to the public too) that is about 25km from the house (if I throw in a few detours I can make it a 75km ride just to go get beans). A pound fits nicely in a jersey back pocket.

Most espresso roasts are horribly burnt and over roasted. I like a dark brown roast, never black.

I drink no more than 2 2oz shots a day (no sugar), and almost never any drip or other type of coffee. Sometimes one of them has a bit of steamed milk. High end Colombian Supremo seems to make the most crema and the most delicious shot (at least from my roaster).

I can go all day without a coffee and do not feel any craving.

They say health wise that unfiltered coffee (press, epsresso, turkish, percolator) is probably the unhealthiest.

Apparently there are oils called terpenes that get into unfiltered coffee that can raise LDL cholesterol (I think). Studies have not shown coffee to raise BP or have other adverse effects on health other than a cafeine buzz from too much joe.
