Chaptalisation

Chaptalisation is the process of adding sugar to fermenting grape juice or must, enriching it to increase the final alcohol of the wine. Wine and food laws permitting chaptalisation vary from country to country and region to region. In most countries chaptalisation is carried using cane sugar. In Australia it is only permitted to use grape juice concentrate. This is typically made from high yield neutral varieties grown in the Riverland and will come in liquid form thicker than honey at concentration of around 70% sugar. It is common practice for winemakers who chaptalise in Australia to use cane sugar to avoid the flavours, aroma and other undesirable components that come in grape juice concentrate.
