As the coffee is rapidly heated it dries up, its chemistry is transformed, its sugars caramelize and its cell structure breaks down. In the process, the properties inherent in the coffee are transformed by the roast and that's where the complexity of coffee flavor comes from: the origin flavors in relation to the “roast” flavors. If you're a coffee nerd, you'll want to check out his interview on NPR about the chemistry of coffee. Cold-brewing does a lot to close the smell-taste gap. I'll really get into this, but first I want to talk about the regionalism of water againand beer too. Remember that first time you drank coffee, as a kid, and the taste didn't quite live up to that amazing smell? The art of roasting is in trying to find the balance that best honors the origin flavor while roasting long enough to develop those flavors in interesting ways. Done properly, this organic method successfully removes 94 - 96% of the caffeine while it retains more of the flavor compounds present in the essential oils than the chemical methods. When it comes to great flavor, coffee chemistry boils down to roasting and brewing. During roasting, oil locked inside the beans begins to emerge at around 400 degrees. Case Studies in Food Safety and Environmental Health. A little spendy at $350, but sure to delight. The more oil, the stronger the flavor. The chemical compounds applied to your flavored beans will leave a sticky residue that's hard on equipment lifespan—and will create a legacy of flavor-schmutz you pass on to each new coffee you grind. This book is the one for them, a “comprehensive review of coffee flavor chemistry” with a focus on analytical techniques for roasting, brewing, and harvesting coffee. He touches on some neat stuff, like what changes coffee beans go through as they move But if you have too much caffeine, it will, in fact, be toxic . So bitterness is a flavor that we learned to enjoy in the course of our lives because we can associate it with desirable things like the delicious flavors of coffee and the stimulating effects of coffee. Depending on what method is chosen the water chemistry is affected and therefore coffee flavor will also be affected.
