#1234 1978 · Robert Parker (The Wine Advocate) · Wine criticism
Parker replaced flowery wine descriptions with a number readers already knew how to read
the problem
Wine critics wrote verbal impressions that varied writer to writer, giving buyers no way to compare wines across regions
background
Wine writing before Parker described quality in prose — elegant, structured, disappointing, brooding — language that conveyed a critic's impression but gave no consistent way to compare one wine against another, let alone one region against a different one entirely. Existing British publications like Decanter scored major tastings on a 20-point scale, but Parker, a Baltimore lawyer, found it too coarse: with only twenty possible values it couldn't separate a merely good wine from an exceptional one, and 20-point scores from British critics were frequently entangled with commercial relationships to the merchants and estates being reviewed.
Parker wanted a rating any consumer, not just a wine expert, could read instantly and trust as independent, since he took no advertising and accepted no samples with strings attached. A finer descriptive vocabulary wouldn't solve the comparability problem — two critics' 'excellent' meant different things, and words couldn't be ranked against each other the way two numbers could.
what everyone would do
The available options were sharper descriptive writing, which still couldn't be ranked against another critic's sharper writing, or adopting the existing 20-point scale British critics used, which was too coarse to separate good wines from great ones and was compromised by commercial ties to the trade.
what they saw
The problem wasn't vocabulary, it was units — readers needed a number, not adjectives, to compare wines across regions. Parker chose the 100-point scale because Americans already knew how to read it from school.
the move
Parker launched The Wine Advocate in 1978 using a 50-to-100-point scale borrowed from the American school grading system everyone already understood instinctively, awarding points for color, aroma, flavor and overall quality and potential, and refusing advertising or free samples so the number stood as an independent judgment.
why it works
A 100-point scale borrowed from grade school meant readers didn't need to learn a new system — a 92 registered instantly as excellent without any translation, unlike a 20-point score or a paragraph of tasting notes. Because Parker also refused advertising and samples, the number carried the added weight of appearing independent, so the market treated his score as a clean, tradeable signal rather than one more subjective opinion among many.
the payoff
By the 1980s Parker's 90-plus scores could move Bordeaux futures prices and shift demand overnight, more than any single critic before him.
where it breaks
A single number this powerful invites gaming: winemakers began crafting wines specifically to score well with one critic's palate, distorting style choices industry-wide, and any scale that concentrates that much pricing power in one person's taste is only as reliable as that person's independence and consistency.
what came after
The 100-point scale became the industry default, adopted by Wine Spectator and most major critics, and Parker's scoring habits so reshaped how wineries make wine to chase high numbers that critics now debate 'Parkerization' as its own stylistic force in winemaking.
