I'm trying instant coffee for the first time and thought that it tasted like drinking a flat tire. After experimenting with different condiments I came to realize that the offensive taste was from the foam that appears at the top after stirring in the powder and not the liquid itself.
The taste of the foam is bitter and extremely distasteful. But if I spoon it off then the coffee itself is just fine.
I am new to instant coffee and have only tried Nescafé Taster's Choice and Café Listo de La Salvadoreña.
Is this a common theme among instant coffee? Possibly a result of the drying process?
