SCIENTIFIC COFFEE (Part Two)

We've been reading a number of blogs about the science of brewing coffee and last time we talked about buying good coffee beans, grinding right before brewing, proper storage, water to coffee ratio and technique.  You’ll find them archived on our blog site and here are some more hints:

Use quality tools: You're going to get better results from high quality tools than you will with junk from the bargain bin. Yes, it's more of an upfront investment, but in the long run it's worth it. Good tools last longer and make the entire brewing process much easier.

The grind size of your coffee beans: Grind size affects the extraction rate because it affects surface area. Beans that are coarsely ground have less surface area than the same amount of finely ground beans, making it more difficult for the water to penetrate and extract the coffee solids. A uniform grind size means that the extraction rate of the oils and acids in the coffee will be consistent. You won't have large pieces that under-extract and small pieces that over-extract. It's for this reason that you'll often hear coffee experts exhorting people to invest in a good burr grinder. And guess what? They're right.

The temperature of your water: Temperature affects extraction rate because solids dissolve more quickly at higher temperatures. Temperature also affects flavor because it determines which solids get dissolved. Using water that's too hot will lead to sour coffee since it releases unpleasant acids from the coffee beans. For this reason, we recommend brewing with water between 195 and 202 degrees. And remember, measure the water actually in the coffee and not just what you're pouring. There's often a difference.

The amount you agitate your coffee grounds during brewing:You can further manipulate the brewing process by agitating the coffee grounds as the water passes through them. Agitation works because it accelerates the spread of dissolved coffee solids throughout the water, exposing the coffee grounds to fresher water more quickly. But agitation also has the effect of cooling the water, which we know can affect the process. In the end, it's just one of those things that you learn through trial and error.

The ratio of water to coffee: Strange how it keeps coming back to this, right? The key difference here is that when you're fine tuning, you aren't sticking strictly to the Golden Ratio. Instead, you're adjusting to taste. To make adjustments more easily, invest in a scale. You can be more precise by using weight—instead of volume—to measure your coffee and water.

Pretty scientific, huh?
