My name is Mike Jones, and I'm a barista at Third Rail Coffee right by Washington Square Park in New York City.
-
I'm going to teach you some basic coffee-making skills.
-
Alright so you have the green beans, it's been harvested, processed from the country, and now it's at a roaster.
-
It's still not ready to be drunk. What this goes through is a process that is
-
that involves adding heat to the bean. Slowly, basically cooking it
-
in order to get it to the desired temperature to bring out everything that you want in a bean.
-
So this happens at temperatures ranging from like 392 to 400 plus degrees Fahrenheit.
-
What happens there is the starches in the bean actually caramelize. And so they turn into simple sugars.
-
It breaks down the protein cell structure and becomes less dense.
-
This all sounds very technical, but basically whats happening is you're pulling out the flavors within the green bean.
-
That if you were to just pulverize that green and try to brew it,
-
it would just taste like nothing, but this way its actually able to be ground and
-
have all aromatics and flavors released once you put it in contact with hot water.
