[Q]: Question: There is a particular taste that I could never quite translate in English. It is not bitter, although it sometimes occurs with it. The best example is eating a raw quince fruit. The mouth and tongue get a sort of dry feeling. Similar taste can be experienced with some persimmon fruit, and unripe plums. I know the word in French (apre) and Bulgarian (). Google translates these as rough, but that somehow seems unlikely. Any ideas?
Answer: I think you may be describing the sense one also often gets from grape juice, which is a dry sensation throughout the mouth, even though it's full of liquid. That flavor and taste is called "sec." Sec is another way to say medium dry, un-sweet and is borrowed into gastronomy from wine world.
[A]: no

[Q]: Question: Please tell the single word for "to completely root out a disease".
Answer: Depending on the disease's cause (A virus, bacterium or other living creature): Exterminate might be a more fitting phrase.
[A]: no

[Q]: Question: I believe there is a term for a person who uses 'expert sounding' terminology and exudes confidence, even when their actual abilities are significantly short of their 'presentation'. Using 'wine' a subject.... if a person described a taste as: Magnificent bouquet, the esters resonate with hints of mulberry and asparagus. This must be an oak-matured red from Bordeaux. Perhaps.... 2003 vintage, that was a year when unusual rainfall produced an outstanding crop that had the same rich tannins. A person describing the wine like that has apparent confidence, apparent technical expertise, and so on. Yet, if he was a fraud, and knew nothing about wines, and the "wine" was really vinegar.... what would you call that person? Additionally, this would not be a one-off thing. This would be a person who consistently "bamboozles" people, and only when you dig below the posturing, or put them in the company of a 'real' expert, do you see the reality. A fraud, a cheat, an imposter. Those would be true, but I'm sure there's a word which also covers the confidence, charisma, and presentation style too. I just can't think of it.
Answer: My first thought for this would be charlatan:- A person who makes elaborate, fraudulent, and often voluble claims to skill or knowledge; a quack or fraud. [American Heritage Dictionary via The Free Dictionary] Another possibility would be mountebank:- a boastful unscrupulous pretender [Merriam-Webster].
