There are two main aspects to judge whether the raw beans are fresh or not.
1. Appearance: whether the color is bright green and shiny (most raw beans treated with water will be emerald green as long as they are fresh).
two。 Raw bean smell: generally, if not water-washed beans, such as dry mocha, semi-washed manning and so on, it may be difficult to tell how long the beans have been kept by their appearance, but the smell absorbed by raw beans provides a very obvious clue. When fresh, the smell of washed raw beans is fresh grass, while that of dried mocha beans is fermented with ripe fruit, and the smell of semi-washed Mantenin is less obvious. but do not have a stinky, like stinky tofu and other long-lasting bad wet rot smell.
Fresh raw beans, full of vitality
Semi-fresh raw beans with a little bit of stability in their vitality
Eight months later, the raw beans lost their vitality.
Raw beans for more than a year are old and boring
However, the above comments are only applicable to general coffee beans & in general preserved state.
Not suitable for specially treated beans and special preservation environment
Such as low cause treatment, aging, wind stain treatment and so on.
That's another area of appreciation.
