Coffee Starts Green

Every cup begins on a branch. A coffee cherry ripens from green to a deep, glossy red, and when it is ready it is picked, often by hand, one branch at a time. Inside the fruit sit two seeds. Those seeds are what we call coffee beans.

After harvest, the fruit is removed and the seeds are dried, then sorted and packed into sacks for their journey. Washed, natural, honey: the way a producer handles this step already shapes much of the coffee's character, long before it ever meets a roaster.

Open a sack of green coffee and the surprise is how little it looks, or smells, like coffee. The beans are pale, matte and firm, somewhere between olive and straw. The scent is faint and grassy, closer to dried herbs than to anything you would brew.

This is the real starting point for every coffee, from a morning espresso to a slow weekend filter. A green bean holds potential: sugars, acids and oils waiting for heat.

Put a green bean next to a roasted one and it is hard to believe they are the same seed. Roasting is where the story changes.

As the beans heat up, they lose water, expand and turn from green to yellow, then to brown. Sugars caramelize, and the Maillard reaction builds hundreds of aroma compounds. Somewhere along the way the beans crack audibly, and a good roaster listens, watches the colour and times every stage, because a few seconds can move a coffee from bright and fruity to deep and chocolatey.

The bean is the same. The story is not.

That is why roasting is the heart of what we do at MOGI. The origin, the variety and the producer's work give a coffee its potential, and the roast decides how that potential reaches your cup: the aroma when you open the bag, the sweetness, the body, the finish.

Next time you pour a coffee, think of the whole path. A red cherry on a branch, a pale green seed in a sack, and a roast that brings it to life.
