Antioxidant Protection during Harvest |
Enartis Vinquiry can assist winemakers in protecting, enhancing and preserving grape and wine aromas throughout the winemaking process. Antioxidant protection is important to consider as soon as the grapes are crushed to protect against browning, loss of color, bitterness, herbaceousness and the loss of varietal aromas. Antioxidant products used in winemaking, include ascorbic acid, tannins, sulfur dioxide and glutathione.
Enartis Vinquiry has a few products to choose from that accomplish protection against oxidation. AST is an excellent choice at the crusher or press because it is a blend of potassium metabisulfite (SO2), ascorbic acid and a hydrolysable tannin. These three components work synergistically for effective antioxidant and antimicrobial protection. AST has also shown to be effective in the prevention of atypical ageing. Winy is a pure, high quality potassium metabisulfite that can also be used at all stages of winemaking. The yeast derived polysaccharide, Prolie Blanco, can also be paired with these products for extra protection because of its high glutathione content. It also contributes free mannoproteins which result in wines that are fresher, more stable, softer on the palate, and have more intense and lasting aromas.

Berry Analyses during the Upcoming Harvest |
Monitoring your grapes during ripening can help you make the most important decision - when to harvest. Berry analyses throughout the summer months can provide important information on fruit maturity and berry variability in the vineyard. These parameters are valuable when tracked year-to-year to create a history on the selected vineyard. Enartis Vinquiry offers the following services to help you monitor your grapes:
Berry Variability
Variability of berries often results in unripe fruit and undesirable characteristics. Many factors can be attributed to variability in the berry, cluster, vine and block. These factors include length and evenness of bloom and fruit set, canopy density, crop load, fruit thinning, fruit exposure and other viticultural practices. Although there are some factors that a winemaker can’t control, there are others where techniques can be adjusted to achieve more uniformity. Enartis Vinquiry’s Berry Variability assay will give information on the uniformity of the vineyard which in turn leads to better understanding of the vineyard site. It is a tool that will help winemaking and vineyard staff to make informed decisions for total quality management. Included in Berry Variability:
 |
Berry Weight Average |
|
Brix Reading for 300 Individual Berries |
|
Composite Titratable Acidity |
|
Composite pH |
|
Composite Brix |
Grape Quality Monitoring Panel - Panel 11
The Grape Quality Monitoring Panel (GQMP) is one of Enartis Vinquiry's newest panels. The parameters included in the panel provide one with a good idea of the fruit's condition and its ability to ripen further. In order to obtain optimal grape ripeness for premium winemaking, field samples should be collected and tested over time. Included in the GQMP:
|
Berry Weight |
|
Berry Count |
|
Brix |
|
Titratable Acidity |
|
pH |
