The English, then the Dutch and Scandinavians [5] from their demand for wine, created a craze for planting between Bordeaux and La Rochelle. Little dry white wine was produced for export from La Rochelle [b 5] while Bordeaux exported mainly wines from the hinterland received via the Garonne.

The native enzyme (E) is oxidized by hydrogen peroxide (H 2 O 2) to an active intermediate enzymatic form called compound I (E i).Compound I accepts an aromatic compound (AH 2) into its active site and carries out its oxidation.A free radical (AH·) is produced and released into solution leaving the enzyme in the compound II (E ii) torosgazete.comnd II oxidizes a second aromatic molecule.
