AccuVin Quick Tests and Accu Vin Wine Tests

AccuVin Quick Tests - Full Pocket Lab (Sampler Pack) - (less D-Lactic). The Pocket Lab test are complete as below, but with smaller numbers of tests and samplers (D-Lactic tests are NOT included). There are 5 tests and 5 samplers in the pH, Titratable Acid, Malic Acid, Free So2 and Residual Sugar kits and 3 tests and 3 samplers in the L-Lactic Acid kit.

AccuVin Quick Tests - Free So2- 10 tests. The sulfur dioxide present in must and wine is not all useful as a preservative. Some is bound to other chemical components, reducing its effectiveness as a preservative by 30 - 70%. Also, the degree of binding can change over time, affecting the ability of an adequate dose to continue providing its preservative properties. The effectiveness of sulfur dioxide as a preservative is also pH-dependent, with low pH wines requiring lower levels, and high pH wines requiring significantly greater concentrations to achieve the same effectiveness as in a typical wine with a pH of 3.3 - 3.4. The Accuvin Free SO2 Kit is divided into a Low Range (0 - 40 ppm) and a High Range (40 - 130 ppm). The Free SO2 Kit includes 2 High Range Tests (red caps) and 8 Low Range Tests (green caps), 10 samplers, and an insert with complete how-to-run instructions. The insert also includes a Summary Interpretation explaining how to use the test results. The label with the color chart is on the front of the kit.

AccuVin Quick Tests - Titratable Acid - 10 tests. The level of titratable acidity is important in optimizing extraction of flavor components prior to fermentation. During processing, controlling TA improves fermentation. Post fermentation monitoring of acidity levels leads to correct balance, and improves the efficacy of aging. Post fermentation monitoring of TA levels can also be used to follow undesireable changes caused by yeasts or bacteria. The range of the TA Kit is from 4.0 - 11.0 g/L as tartaric acid. The TA Test Kit includes 10 tests, 10 samplers, and an insert with complete how-to-run test instructions. The insert also includes a Summary Interpretation explaining how to use the test results. The label with the color chart is on the front of the kit.

Accuvin Quick Tests - pH - 10 tests . As one of the key parameters of interest to the winemaker, pH is an important factor in selecting the optimum time to harvest grapes. It is measured to see if adjustments need to be made prior to primary fermentation. It is measured when adding sulfur dioxide as a preservative since the effectiveness of this chemical varies dramatically as pH changes. And pH is controlled to optimize conditions for fining, for improving a wine's resistance to microbial instability, and in defining a wine's balance. The pH test kit is optimized for enology use with a pH range from 3.0 - 4.0, and a sensitivity to 0.1 pH unit. The pH Test Kit includes 10 tests, 10 samplers, and an insert with complete how-to-run test instructions. The insert also includes a Summary Interpretation explaining how to use the test results. The label with the color chart is on the front of the kit.

AccuVin Quick Tests - Residual Sugar - 10 tests. The ACCUVIN Residual Sugar Kit tests only for fructose and glucose sugars, the sugars reduced in primary fermentation. Reducing sugars in wine consist of hexoses (mainly glucose and fructose) and pentoses (mainly arabinose and xylose). The pentoses are not fermentable by wine yeasts. Since pentoses alone can vary from 0.4 - 2.0 g/L, the best measure of primary fermentation is the determination of glucose and fructose. The test range is 100 - 2,000 mg/L. The Residual Sugar Test Kit includes 10 tests in a black barrier tube, 10 samplers, and an insert with complete how-to-run test instructions. The insert also includes a Summary Interpretation explaining how to use the test results. The label with the color chart is on the front of the kit.

AccuVin Quick Tests - Malic Acid - 10 tests. Malolactic fermentation, the secondary fermentation of winemaking, is a method for reducing total titratable acidity by adjusting the relative concentrations of L-malic and L-lactic acids, softening the wine and allowing it to develop mellowness and full-bodiedness, This process also results in enhanced microbial stability since one of the key nutrients of spoilage bacteria is removed. The Malic Acid Kit has a range of 30 - 500 mg/L. The Malic Acid Test Kit includes 10 tests in a black barrier tube, 10 samplers, and an insert with complete how-to-run test instructions. The insert also includes a Summary Interpretation explaining how to use the test results. The label with the color chart is on the front of the kit.

AccuVin Quick Tests - L-Lactic Acid - 5 tests. The L-Lactic Acid Kit is intended for measuring the L-lactic acid in wines to ensure that malolactic fermentation has begun. It is not always easy to determine if the appearance of bubbles following primary fermentation is the onset of actual MLF or merely a wine outgassing as it warms. The product, with a test range of 10 - 400 mg/L, can also be used to screen for high levels of contamination by lactic acid bacteria. The L-Lactic Acid Test Kit includes 5 tests in a black barrier tube, 5 samplers, and an insert with complete how-to-run test instructions. The insert also includes a Summary Interpretation explaining how to use the test results. The label with the color chart is on the front of the kit.
