Coffee Science: How to Make the Best Pourover Coffee at Home
"Most of the roasted coffee bean, about two thirds of the bean's mass, is insoluble cellulose. The other third is dissolvable in water. Of that soluble third, most of it is the good stuff, particularly various organic acids and sugars. The rest are longer-chain molecules that we associate with astringent and bitter tastes. Where we find the happy balance is at the 19-20% point, that is, if you extract the first 19-20% of the mass of the coffee, we tend to find the best flavor balance. More than that and you'll find those astringent and bitter flavors start to dominate. Less than that and you'll find the resulting flavors thin and unbalanced, and with lighter roasted coffees, unusually sour. Timing really is what makes or breaks your coffee brew." [more inside]

The Caffeine Examiner
will review any
product containing caffeine. For example: chewing gum
, energy drinks
, soft drinks
, hard drinks
, perplexingly hard drinks
The sidebar on the right points to reviews of more caffeinated products than I had ever dreamed existed. Products are also rated by taste, packaging, nutrition/buzz, and website functionality. [via]

DAMMIT, DOSED AGAIN! Well, once again I got a cup of full-strength this morning which she swore was decaf, and I'm jittery as a chimp on crack. But soon I won't have to worry; chemists at Washington University School of Medicine are working on a caffeine test strip.

Fox pussies out.
Recently a bill passed in mexico legalizing all drugs
under certain specified quantities. The bill was promoted By Vincente Fox's party, and came from his offices. However he decided not to sign it under U.S. pressure.
There go my vacation plans.

black and white film at home just got much cheaper
. It's possible to develop film using tea, coffee, or even vitamin C. To avoid being called a fustian photography nerd, call it caffenol
, but not that

Death By Caffeine
I just learned that it would take 155.11 cans of Mountain Dew to kill me, according to this odd little service.

1,3,7-trimethylxanthine (sometimes used as a pesticide to kill frogs) also happens to be one of the world’s most popular drugs.
Users find that it improves attention and concentration, and slightly decreases their heart rate at low doses. It is habit forming however and has been known to cause agitation, anxiety, insomnia, disorientation, nausea, delirium, hallucinations and tinnitus. Some people report involuntary tremors or even convulsions. Overdoses can cause seizures, respiratory failure and cardiopulmonary arrest. Withdrawal from regular use can cause symptoms including headache, nausea, nervousness, reduced alertness and depression.
The metabolic half-life of the drug is usually somewhere between three and seven hours so a typical user will take somewhere between fifteen and thirty-five hours to process 95% of their initial dose. How many milligrams
have you taken today?

How do you get teens to crave milk? Load it with caffeine.
"We're giving teens the caffeine they want but also vitamins, calcium and protein" ...and also a lot more calories.

Will 2003 Be The Year Of Real Espresso In America?
With the wealth of good machines
, fresh coffee beans
and online knowledge
, not to mention tempting offers like Illy's subscription
(though the pods turn out expensive in the end, it allows absolute beginners to make acceptable espresso) it's surprising Starbucks-style coffee (big, milky, watery and sweet) hasn't yet been dethroned by the pleasure of straight espresso (tiny, thick, creamy and intense), preferably restretto
. I should add that, despite many efforts over the years, I've never had a decent cup of espresso in America. In fact, outside Southern Europe. What gives?

"How Much Starbucks is Too Much?"
This article predicts that our favourite caffeine pushers could double the number of outlets in the US without saturating the market. Pretty graphs, but has anyone told this guy about Starbucks' more sinister plans
? warning, second link = Onion story

Isolating the gene responsible for caffeine
is expected to lead to decaffeinated beans, and a higher-quality coffee product, all-around... But are they considering other applications? With a bit of gene splicing, anything is possible. Caffeinated oranges, anyone?
