Is there really much difference in taste between instant coffee brands and supermarket instant coffee?
Sometimes not that much difference. Supermarket brands can be just as good as the leading brands – I have often found I prefer the supermarket ones. The only ones I have found to be bad are the value range ones – they can be horrid. Drinkable (just) but not my drink of choice! It all depends on how you like coffee, though. Some of the leading brands I cannot stand. However, I find that most of the coffees for the British market pretty horrid. I had Nescafe in Spain and it was lovely! Now, I get my Nescafe from either semi Chem or pound shops – those are from Brazil, I think, and are a totally different blend to the British ones – far nicer, I think. Plus the bonus is they are half the price of the leading brands in the Supermarkets!
