We can safely extrapolate that this research shows humans are not naturally inclined to drink bitter ashy woody burnt acrid tar-like coffee. We are more likely to prefer sweeter tasting coffees. That's a high-five for 3rd wave cafes!
Specialty Coffee is fresh, being served and consumed within 3 to 14 days from roast date. By contrast, commodity-based coffee will mostly be what we consider as stale. Specialty Coffee bags have ‘birth dates’, whereas commodity-based coffee bags have ‘death dates’. Most specialty roasters are transparent. They openly display the day it was roasted and also reveal the beans used, including the names of the farms.
Our understanding of how taste information is carried from the tongue to the brain shows that individual taste qualities are not restricted to a single region of the tongue. There are two cranial nerves responsible for taste perception in different areas of the tongue: the glossopharyngeal nerve in the back and the chorda tympani branch of the facial nerve in the front. If tastes were exclusive to their respective areas, then damage to the chorda tympani, for instance, would take away one’s ability to taste sweet.
Apparently Umami isn’t a primary taste.
Not the same as bitter, salt, sour and sweet.
Umami is proposed to be reliant on sugar/salt receptors to be tasted. Lacking independence removes it from being a primary taste.
And that fat is not a primary taste either because it doesn’t create a hedonic response.
How does this change your tasting of coffee? Should we be so concerned in trying to identify Umami when it is actually perceived through the Sugar and Salt pathway?

There are many sieves for coffee but few match Kruve’s surface area, speed and efficiency with the likelihood of it not clogging, falling apart and making a mess of the counter and floor. We found the Kruve easier to handle than some other versions of coffee sifters with the gaskets attached to the screen and easily inserted into the metal holders - which was really pragmatic.
