0 - 49 Unquestionably terrible! Should be stored in industrial drums.

70 - 74 Drinkable but seriously flawed.
75 - 79 Drinkable but somewhat flawed.
80 - 84 Enjoyable, mostly unflawed, some character
85 - 89 Delicious, unflawed, robust character
90 - 94 Delicious, Exquisite, potent character
95 - 99 Superstar Whisky
100 “The best thing I ever put in my mouth!"
M Jackson’s Scoring System
50's - These in all fairness were probably not meant to be bottled as a single malt. Lacking balance and character
60's - Suggest enjoyable but unexceptional malt
70's - Anything in 70’s especially beyond 75 is well worth tasting
80's - Distinctive and exceptional
90's - The truly great malts
