I jumped on this at first as well. But to be honest if their target demographic is industrial production of coffee like beverages (like those Star Bucks soda can ”coffees”), well then it might not be so bad. I was thinking that a lot of flavour compounds of espresso breaks down quite rapidly while the drink cools, so the method of cooling all drinks to equal temperatures could be enough to skew the results regardless, but again for commercial coffee based soft drinks this is already the case. Headline is a bit misleading though.
I like good quality coffee.
But I also need my coffee: I'll drink whatever quality coffee is being offered, as long as it's the best I can get that morning.
Wine ruins the taste of coffee regardless of colour
Sure you can. You can absolutely use those 100 participants if your aim is to develop and market a process that can then be used to make a product for those same types of people. Samples generalise if your sample is representative, and in this case, for large commercial coffee extraction companies, third wave coffee aficionados are not in their target audience.
