Gravimetric analysis of CDTA and NaOH extracts of alcohol-insoluble residue (AIR) from wine (Cabernet Sauvignon) and table (Crimson Seedless) grape berries

	Cabernet Sauvignon	Crimson Seedless
CDTA
Green	21·5 ± 1·8a	34·4 ± 8·0d
Véraison	30·8 ± 6·3b	33·9 ± 5·1d
Ripe	30·1 ± 5·2b	24·0 ± 6·6e
NaOH
Green	38·7 ± 4·2c	21·8 ± 5·4e
Véraison	41·5 ± 3·6c	20·1 ± 3·1e
Ripe	45·9 ± 7·0cd	28·7 ± 4·1f

Data (mg per 100 mg AIR) represent mean and s.d. of the mean for n = 8 samples per cultivar per stage.

Different letters represent significant differences (P < 0·05) between extract yields within each extraction set.
