Why sources disagree on white wine
The 2 studies here run from <1 to <1 mg per 5 oz glass, measured between 2021 and 2023. Variety, growing conditions and lab method all move the number. Every one of them lands in grade A.
Where this number comes from
Each row is one published measurement, converted to a 150 g serving (5 oz glass). The grade and the range use the rows prepared the way the serving is eaten, and take the middle. How the grades work.
| Per serving | Per 100 g | Preparation | Source |
|---|---|---|---|
| <1 mg | 0.2 mg | Not stated | Harvard T.H, 2023 |
| <1 mg | 0.3 mg | Not stated | Siener R, 2021 |
