I'm not sure picking the world's most expensive cup of coffee is a representative sample of what a cup of coffee costs.

How much does a representative sample of a cup of coffee cost?

The coffee I drink costs about $0.10 a cup.

In Seattle, a ~350ml cafe-latte (~310ml milk, 40ml coffee) is around $3.50 (can be $4.50 downtown, $5.50 at airport) - this commonly called the 'Double Tall Latte' - our local news media uses it as a cost comparison for dang near everything.

I never understood why people spend so much when you can make at home for so much less. (Apparently 1/10 to 1/50th of the cost?!?)

Do people really consider a cup of coffee cheap? It seems expensive enough to be considered an occasional treat, not a daily purchase.

It's definitively a small luxury item, but can't really argue with anyone's spending habits.

More relevant, "cups of coffee" is not a good unit of measurement and can be misleading. Just say the number and trust that people can cope.

Other offenders: Measuring distance in "cars lined up from here to the moon", expressing data in "Libraries of Congress", or expressing cost in $/day instead of $/month or $/year.

I currently spend about a dollar a cup to two dollars a cup for black coffee. Mostly because seems like it would take a few hundred dollars worth of experimental purchases and a reasonable number of hours to match the quality I get form local cafe.

If I move to another city or If I decide I have time/money for the hobby I will do.

A representative cup of coffee costs $3-$5 and is not the same as a cup of coffee you would enjoy at home, which is not measured in cost per cup.

> This is said to be the world's most expensive Starbucks coffee featuring 60 espresso shots and costing $55 (£33).

That's a lot of shots! How many espresso shots is enough to kill someone?

Death by Caffeine[1] says 172.84 espresso shots to kill a 195lb human.

I'm upvoting this because coffee should cost fifty cents a cup.
