Coffee – Does the foam from instant coffee always taste bitter

coffee

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?

With proper coffee the foam is referred to as crema. It is typically quite bitter itself (as coffee tends to be anyway), which seems to be a function of the emulsion of the aromatic oils in the crema and CO2 from the bubbles. I don't know that the crema on an instant coffee is any more bitter than the crema on an espresso

Instant coffee aims to replicate the crema to give the appearance of a quality coffee. I have found (I'm from NZ, where we drink quite a lot of instant coffee generally), that instant coffee tends to have a faint chemical taste in the crema that isn't present in an espresso coffee. I suspect this is a result of the process of manufacturing instant coffee, or even perhaps as a result of aiming to get a crema on the instant without the pressurized equipment used to make an espresso coffee
