BRIX LEVELS
What is BRIX?
The Brix scale is a system used to measure the sugar content of grapes and is typically used as a simplified measure of ripeness. The Brix of juice from crushed grapes is determined using a Hydrometer, which measures specific gravity (the density of a liquid in relation to that of water). Each degree Brix is equivalent to 1 gram of sugar per 100 grams of grape juice. The grapes for most table wines will have a Brix reading of between 17 and 24 Brix at harvest, depending on the grape variety and with an average of about 21 or 22 degrees. Most of the sugar in the grapes will be converted into alcohol during fermentation. Grape ripeness and flavour is also impacted by acidity and complex phenolic character and winemakers often rely on tasting the grapes for their final decision about when to harvest.

If rosé and blanc de noirs wines carry a viticultural area designation, each grape variety used in the making of these blended wines is required to meet only the minimum average Brix level for the Ontario Provincial designation for each grape variety, as set out in the Column 2. Wines approved under this rule must declare Rosé or Blanc de Noirs on the label.
Vin de Curé wines are required to meet the minimum average Brix level for the grape variety at harvest as set out in Column 2 or 3 according to the geographical indication that appears on its label. After the grapes are dried, the resulting must shall achieve a brix of at least 27 degrees as tested by VQA Ontario's independent agent.
The minimum Brix for all component grapes used in VQA wines shall be 17.0 º Brix after each pressing when measured after transfer to the fermentation vessel, except for grapes used in Sparkling Wines.
The minimum brix requirements listed above for wines designated with the provincial designation "Ontario" apply to all grapes and wine content harvested in the vintage 2011 or later. A minimum brix of 17 degrees applies for all varieties for grapes harvested in 2010 or earlier used in Ontario designated wines.
