Do your homework before buying coffee beans

Choose the store you trust.

Rather than buying coffee beans from famous stores, it is recommended that you buy them in your own roasting cafe. Because coffee beans from some famous stores will be roasted abroad, it will take at least two months to ship the beans from abroad to Taiwan and then to consumers, and once the raw beans are roasted, the flavor will gradually lose and become stale. The fresh period of raw beans can be maintained for about 2 years under good preservation conditions.

Green green raw coffee beans are the best.

The appearance of normal raw beans is light green, if there are small black holes on behalf of moth-eaten, brown spots represent mildew, if yellow or black, it means mildew is more serious, or even acidified.

Choose roasted coffee beans like this: see, smell, peel.

POINT 1: "look" surface grease

Shallow baked beans, whether freshly baked or placed for a long time, there is little oil on the surface. The deep oil of deep baked beans will be released to the surface after baking at high temperature, and obvious oil droplets will appear. Do not think that it is not fresh, and then after mixing and packaging, the fat will be evenly distributed on the surface of coffee beans.

Coffee beans have different flavors according to the heat, shallow roasted coffee beans show distinct clear acidity; medium heat roasting shows sweet and slightly sour; deep roasted coffee drinks thick throat rhyme. Hand-picked beans to remove damaged beans can avoid affecting the flavor of coffee. It is recommended to purchase unground baked beans in order to see the quality of complete beans and to maintain the freshness and aroma of beans before brewing.

POINT 2: smell the fragrance

Fresh shallow baked beans have fresh fruit, spice and honey aromas according to different producing areas, while deep baked beans have chocolate and drupe aromas. If the coffee beans are not fresh, they will smell of fuel consumption, whether light roasted or deep roasted.

POINT 3: peel off with your hands

Fresh coffee beans have less moisture and hard tissue, so it is not easy to peel them in half with both hands, while stale coffee beans absorb moisture in the air for a long time, and the tissue is soft and easy to peel into two halves.

POINT 4: check the outer package

The design of breathable valve is better.

Roasted coffee beans will continue to release carbon dioxide for 1 to 2 weeks, causing coffee packaging to expand. It is recommended not to buy vacuum packaging, which means that it is not in the carbon dioxide release period. You can choose the packaging with opaque aluminum foil and one-way breathable valve on the surface mask, carbon dioxide can be discharged, but oxygen will not enter to make it stale.

Pay attention to the date mark

Self-baking coffee shops usually stamp the date on the package on baking day rather than packing day. It is recommended to buy about half a pound at a time and drink it within a month.
