Five points for attention in coffee roasting Coffee roasters know how to roast unique coffee beans

Now, it's not surprising to have a coffee roaster. Many boutique coffee shops have their own coffee roaster and their own coffee roaster, which makes coffee roasting technology develop and mature.

Have you ever wanted to know what a coffee roaster is? do you want to know what will happen in the roaster when you put the raw coffee beans in it?

Compared with experts, what is the advantage of experienced roasters teaching us how to bake coffee? So I asked Counter Culture Coffee's Brett Donahue and Stumptown Coffee Roasters's Jim Kelso to teach us how to better understand coffee roasting.

As Kelso says, coffee roasting is "a simple but at the same time the most complex aroma experience I've ever experienced."

Hearing what he said, does it make you full of interest and expectation for coffee every day? If you are learning how to bake coffee, listen to these two experts' five tips for all beginners.

1. Coffee roasting is a technical job.

Have you ever seen a coffee roaster but don't know how it works? Donahue outlined how to do it: "the first step in roasting coffee is to put the raw coffee beans into a spinning drum where there is a strong stream of hot air passing through the drum at a temperature of up to 400 degrees. The coffee beans in the sun drum will undergo thousands of chemical reactions and physical changes as the temperature increases, especially the Mena reaction (imagine a bread baking) and caramelization, until the coffee beans reach the correct aroma and sweetness. the coffee beans are almost done. Open the door cover in front of the machine, pour the heated coffee beans into a cold air plate and stir until the temperature drops to the indoor temperature.

two。 Coffee roasting is an art.

When you cook or barbecue food, you can't make delicious food by following the recipe. In fact, gourmet cuisine is an art in which foodies combine years of knowledge, experience and personal intuition, and so is coffee roasting.

"there may be a misconception that digital baking machines can solve all the problems and that we just need to do some cleaning," Kelso said. In fact, however, even the best coffee roasters I have ever seen roast coffee beans based on their intuition accumulated over the years with data and technology. "

3. The depth of baked beans may also change the way you cook them.

Although making a good cup of coffee has a lot to do with the thickness and amount of powder, you will find that you are used to using different brewing equipment according to the depth of coffee bean roasting. "I can say that for the same light-roasted coffee beans, some brewing devices are much better than others (any kind of drip filter, such as Chemex)," Donahue said. I personally like to use French pressing to make softer, sweeter Latin American coffee beans, so that the sugar in the coffee can be preserved more intact.

4. Even coffee beans from the same region or origin can be roasted in a completely different way.

Even coffee from different origins, Ethiopia or Costa Rica, does not mean it should be roasted in the same way. Donahue continued: "there are actually a number of different factors that determine what kind of baking is used, such as variety, altitude and treatment process.

Two kinds of washed Ethiopian Yega Chuefei can be considered baking in the same way, but there will be a big difference between washed and naturally dried Yegashafi. So even coffee from the same farm with different heights can be roasted in different ways. "

5. Coffee roasters must know about coffee beans.

"Coffee should be moderately roasted, overbaked and tasteless like dead ash, while underbaked coffee is as tasteless as cereal or hay," Kelso said. It means you have to know the characteristics and origin of your roasted coffee beans. Donahue also believes that coffee roasters need to know about raw coffee beans. "even high-quality raw coffee beans taste bad if they are not roasted correctly," he said. "
