Is it possible to burn coffee while brewing? I know some people who refuse to drink in large coffee chains as they say that the coffee they produce tastes "burnt".

Is it actually possible to burn coffee while brewing, or is the flavour they're complaining about coming from something else?
Burn? I've heard that some large chains "burn" their beans while roasting :-) But not while brewing.

A major coffee chain, seen on almost every other corner in some places, is known for their very dark, "burnt" roast. Many people like this sharp taste and associate it with caffeine and their morning pick-me up.

Other people find this "burnt" roast to be overwhelming and consider this heavy roast to be destructive when using high-quality beans. In any case the burning happens at roast - not when brewing.
