Love good coffee and have sampled many different shops across Melbourne (although so many pop up it's hard to keep track). Double espresso is my drink of choice, and being in sales i range between 3-8 cups a day.
Whilst I've got my favorite spots around town, at home I'm a lot more lax. For the most part I'm only making coffee on the weekend.
My setup is a mid end home espresso machine and grinder (i.e. pretty basic). I try to purchase my coffee as freshly roasted as possible and have a handful of places I purchase from.
Don't measure weights, but when I change to a different bean I will spend a bit of time (~3-5 coffees) playing around with the grind and tamp to figure out what I like.
Aside from all of this the coffee I mainly drink are Vietnamese Coffees, which I must admit is more about the sweetened condensed milk .
