The bottom line is, I love my coffee... I drink strong, black and expensive coffee because I like the taste, and I don't want this filthy vending machine s***[attention]
The above thread was inspired by my looking at some of the guidelines in the social-services handbook on addictive substances (amongst other things). It had a table of how much caffeine fitted into what bands (e.g. okay->addiction->toxic). It also had a table of how much caffeine was in what drinks.
Given that these were rough estimates, I thought I'd try and work out as precisely as possible how much caffeine I consume.
So... I did my research, and I kept a tally of how many cups I drank out of a 100g jar of instant coffee.
100g got me 48 cups.
Robusta beans carry between 1.16% and 2.2% caffeine.
48 cups -> 2.08g of instant coffee per cup
2.08g -> between 24.1 and 45.8 milligrams of caffeine
I averaged 6 cups a day -> between 144.6mg and 274.8mg a day
Thats a lot lower than I was expecting, which is good [smile]
I'm gonna dig up the charts and see which "level" I fit into. More on this later...
