Coffee Chemistry

Coffee Chemistry

I’m a huge coffee nut.

Stop laughing.

Yes, I’m brown-ish, round, and big, but that’s not what I mean :lol: . Let’s rephrase that as: I’m nuts about coffee

You get the idea. ;)

My drink of preference? Papua New Guinea beans through my home espresso machine plus an equal amount of whole milk, sometimes with a spot of condensed milk, chocolate, or caramel. Hot on a cold day, cold on a hot day.

PNG beans are grown in the same region as the more well-known Indonesian Sumatra variety (the country of Papua New Guinea actually shares an island with Indonesia). But unlike Indonesian coffees, PNG beans have their origins in Jamaica. The original seeds for PNG crops are Jamaican Blue Mountain, imported in the late 1920s with new seedlings being imported from Jamaica every once in awhile as needed. So, they share some of the rich, deep flavor of JMB beans but with fruity overtones all its own. Plus, many PNG beans are grown by small, organic-certified farms and sold through a small collective under Fair Trade guidelines, so I know that the beans aren’t being farmed by virtual slaves and the growers are receiving fair compensation. Because of the small-farming method of production (as opposed to plantation-farming) there can be consistancy issues, but I haven’t had any problems yet.

If you want decent taste and 99.9999% consistency then nothing beats Kenyan beans. A few years ago the government of Kenya realized that its domestically-grown coffee was appreciated around the world and was being sold as a premium coffee. In a very smart move they invested heavily on growing the industry and now there is no other coffee-growing country on the planet with a better production, quality control, and distribution infrastructure. The house blends of most major chains, for example McDonalds McCafé, are based on Kenyan beans because they are inexpensive and reliably good-tasting.

 

Conversation over coffee

By the way, much is made over arabica-type beans. I’ve seen plenty of signage around proclaiming “Our beans are 100% Arabica!”. Big deal. The truth is that virtually all coffee out there comes from arabica beans. It doesn’t matter if your coffee comes from Starbucks or Denny’s, it’s going to be arabica. In reality, the only place you are likely to find the cheaper, low-quality robusta beans (grown primarily in Columbia and Vietnam, although Columbia grows arabica beans, too) are in the freeze-dried packets and cans you find in grocery stores.

Enjoy your coffee.

    Interesting post.
    You are a coffee nut though.

    Here’s my opinion on coffee
    The best chain-style coffee: Peet’s Coffee (The company where Starbucks ORIGINATED from)
    The best coffee in the world: Ometepe beans from Nicaragua. Easily the best in the world.

    If you have a chance to get ometepe beans, it’s worth it.
    I just can’t seem to find how I can buy a bag online :(

    Ah, photography and coffee, my two loves. Just found your site from the comment you left on Darren’s blog – hope to meet you at a photo club meeting.

    Can’t say I am an all out coffee conness.. connesiu… dang, what’s that word?! Anyway, I’m kinda fond of the coffee served here in Malaysia by McDonald’s. Pure Arabica, they say. And also, those thick black coffee known as ‘kopi-o’ i.e. coffee without milk that is served at most of the Chinese coffeeshops here. It’s usually made from grinded beans, if my memory serves me correct. As for anything more uppity than that, maybe instant cappuchino in a sachet!

    @Tom: I checked around but can’t find ometepe, although I can get Nicaraguan blends. It’s easier to find real Kona (not that “fancy Kona” rip-off) around here. LOL

    @cfimages: I just happened across his blog. His idea is definately something I’d be interested in. I used to belong to the Photographic Society of Taipei but left a few years ago…kind of sick of “pretty model”, “pretty flower”, etc… . images.

    @teohjitkhiam: The vast majority of coffee out there is arabica, even in the low-end-street-side joints. That’s just the type of bean but not where it was grown. McDonalds uses a primarily Kenyan blend, I believe.
