Is it just me, or is there something fundamentally wrong with single-shot disposable packages being labelled as "sustainable"
Anyway... on the home coffee front, I have many options
Preferred option is my Gaggia Carezza espresso machine. Bought as a new refurbished warranty return through their distributor, who lists such items on Evilbay. Can't remember exactly what it cost, but it was of the order of $200. Only mentioned to point out that a serious good quality espresso machine doesn't need to cost a fortune (the Carezza is basically the innards of a commercial machine (with a smaller boiler, of course) in a cheezy plastic case).
I've got a cheap little Emide burr grinder, which is junk, but I dare not tell Mrs Barefoot who bought it as a present
. When it dies, I'll get something better.
I buy beans wherever. If I'm near a good bean supplier, I'll get a couple of varieties, just to try. Or, if I'm in Ballarat , I get something half decent from the supermarket. I seem to have a lot of Lavazza tins.
If the chillun' are sleepin' (the grinder and espresso machine are a bit noisy), or if I can't be arsed taking the time, I generally do a single-cup drip, with whatever ground floor-sweepings I have in the cupboard . About a decade ago, several brands did a "brick of coffee and one-cup dripper" promo packs, with the same dripper. I have two with different brands stamped on them; one has been used daily at work for about a decade, the other gets occasional use at home. Does a better job than the usual reputation of drip filtered coffee.
Then there's a few plungers of various sizes. Most often used for bulk coffee production when multiple espresso cycles aren't an option.
I'm pretty sure there's a stove-top moka pot somewhere, but it doesn't come out much. I endorse the multiple endorsements for these things though. Bang for buck, can't be beat.
There's also a Kambrook "Mr Espresso", which is like an electrified moka pot, and is absolute junk, so hasn't been used since forever. Should off-load it.
 yes, I'm joking, Ballarat does have good coffee suppliers... but I don't get there during business hours much
 usual floor-sweeping pre-ground coffee is Cafe Aurora Italian-style. It's cheap, and tastes much better than most cheap coffees.
