Basic knowledge of Coffee simply distinguish the advantages and disadvantages of instant coffee
Instant coffee is coffee beans roasted and crushed to get pure coffee, and then extracted and vacuum concentrated into powdered coffee, which can be brewed at any time and dissolve in boiling water. The shelf life of instant coffee is usually two years. Now I would like to introduce the sensory identification of the quality of instant coffee, which can be divided into two stages: before brewing and after brewing.
(1) pre-brewing identification
High-quality instant coffee-brown to dark brown due to different varieties and processes; irregular particles about 2 mm in size, mixed with some fine powder; unique aroma of coffee due to Maillard reaction during stir-frying.
Inferior instant coffee-dark in color, some iron black; caking or agglomeration in tissue due to moisture or other reasons; coffee roasting flavor is weak or can not be smelled at all, replaced by a strong scorched flavor.
(2) Identification after brewing.
Good quality instant coffee-completely dissolved, free of dregs and suspended matter; the soup juice is brown and bright; it has a strong coffee aroma; it has a pleasant bitter and sour taste after adding sugar.
Inferior instant coffee-after dissolving, there is sediment at the bottom of the cup, and the soup is dark and brown-black (at the same concentration); the aroma is light, but the scorched taste is strong; after adding sugar, the bitter taste and sour taste are strong, especially the aftertaste is hard.
