Two varieties in 2020

To Kalon Reserve Fumé Blanc 2020 is 94% Sauvignon Blanc and 6% Sémillon. Fumé Blanc is not a different grape variety; understand the difference between brand labeling and the grape varieties used.

Parcels within the same vineyard

For Sauvignon Blanc, the main source is the Monastery Block, and for Sémillon, the P South plot. Even within a vineyard with the shared name To Kalon, they differentiate between grape variety and plot. Even when there is only one vineyard name, the conditions for the grapes used are not necessarily all the same.

Retain units for components

For the 2020 vintage, the label states alcohol 14.3% and residual sugar 0.80g/L. You cannot calculate residual sugar from the alcohol content. When presenting a wine, record each measurement and its unit, as each value reflects a different aspect.
