# Correlation between 20 point and 100 point rating system

Discussion in 'Wine Talk' started by Trx, Oct 19, 2017.

1. I would appreciate opinions on comparing the AWS 20 point scoring system with popular 100 point systems.
I found that each publication has different meanings for scores in their 100 point scale. A 90 in one system is a silver, in another a gold. It is truly arbitrary.
Wine Spectator tasters review wines on the following 100-point scale:
· 95-100 Classic: a great wine
· 90-94 Outstanding: a wine of superior character and style
· 85-89 Very good: a wine with special qualities
· 80-84 Good: a solid, well-made wine
· 75-79 Mediocre: a drinkable wine that may have minor flaws
· 50-74 Not recommended
A possible correlation from aws 20 point scale to 100. This gives AWS silver medals 90 – 93 points and golds > 94.
20 = 100
19.5 = 99
19 = 98
18 .5 = 97
18 = 96
17.5 = 95
17 = 94
16.5 = 93
16 = 92
15.5 = 91
15 = 90
14.5 = 89
14 = 88
13.5 = 87
13 = 86
12.5 = 85
12 = 84
11.5 = 83
11 = 82
10.5 = 81
10 = 80
<10 = who cares?

That's about how I compute it. Multiply the UCDavis 20 point score by 2 and then add 60.

I typically correlate the AWS with the WS/WA ratings the following way:
100 = 20
97 = 19.5
95 = 19
93 = 18.5
90 = 18
87 = 17.5
85 = 17
87 = 16.5
80 = 16
...............and so on. I just interpolate from my score, based on 20 point scale to the 100 point scale.
Hope this helps.
