the.com/connoisseur

means A person with expert, discerning taste in some field — refined through enough exposure to food, art, wine, or whatever it may be, that their judgment carries real weight.

from Borrowed from French connoisseur (now spelled connaisseur), itself from connoistre, 'to know,' which traces back to Latin cognoscere — 'to become acquainted with, to recognize.' So at its root, a connoisseur is simply 'one who knows,' a cousin of words like 'cognition' and 'recognize.' English picked up the word in the 1700s, keeping the old French spelling even after the French themselves updated theirs.
