There was a bit of conversation in this very good deal (Lavazza A Modo Mio Minu Coffee Machine - Free (up to $25.50 Profit) after $50 Cashback @ Target) about the cost of a cup of coffee.
It came down to this, do you use 1 capsule for a coffee (e.g. cappuccino, latte) or 2 (or more?). Nespresso states to just use 1 capsule on the espresso/small button (e.g. not the long shot). Other similar machines from Aldi, Caffitaly have similar instructions.
Utopian made the point that a cappuccino at a cafe, you will have 1 shot of coffee whereas the amount of coffee produced in a capsule machine only produces half a barista shot. Thus needing 2 capsules per coffee. Probably easier if I quote:
One pod holds ~5grams of coffee. Some brands 4.8 others 5.2
Water to coffee ratio should be 18:1
So 2 pods (or two tablespoons of ground) needs 180ml water, absorbs a bit, yield less than that.
Do you personally use 1 capsule or 2 for a cup of cappuccino/latte?
Use one capsule and and top with frothed milk. Most economical way in my books.
