I am not a coffee edict but I do like it particularly the instant variety. I have drunk quite a lot of percolated/brewed coffee also. But that is usually strong. It does have flavour but that too is strong. For mr mild stuff is the right type. I do not like very strong coffee and therefore, my preference is for coffee-chicory mixture. My favourite is BRU 70% coffee and 30% chicory. It tastes excellent, right taste and flavour for my liking. I take it with a little milk and sugar. Its rival Nescafe is all right but for me BRU tastes better.
I like to take coffee at night. My sleep is not at all affected by tea or coffee. I wish others have the response.
