The pH Test Kit includes 20 tests, 20 samplers, and an insert with complete how-to-run test instructions.

pH, one of the key parameters of interest to the winemaker, 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.
• when adding sulfur dioxide as a preservative since the effectiveness of this chemical varies dramatically as pH changes.
• to optimize conditions for fining, for improving a wine's resistance to microbial instability, and in defining a wine's balance.

The Quick Tests pH kit is optimized for enology use with a pH range from 3.0 - 4.0, and a sensitivity to 0.1 pH unit.

The TA Test Kit includes 20 tests, 20 samplers, and an insert with complete how-to-run test instructions.

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; it can also be used to follow undesireable changes in the wine caused by yeasts or bacteria.

The Quick Tests TA Kit range is from 4.0 - 11.0 g/L as tartaric acid.

The Malic Acid Test Kit includes 20 tests, 20 samplers, and an insert with complete how-to-run test instructions.

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.  This process softens the wine and allows it to develop mellowness and full-bodiedness. It also results in enhanced microbial stability since Malic Acid, one of the key nutrients of spoilage bacteria, is removed.

The Quick Tests Malic Acid Kit has a range of 30 - 500 mg/L.

L-Lactic Acid Quick Tests - For Efficient Monitoring of the Start of Malolactic Fermentation

The L-Lactic Acid Kit includes 5 tests, 5 samplers, and an insert with complete how-to-run test instructions.

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 Quick Tests Lactic Acid Kit has a test range of 10 - 400 mg/L, and can also be used to screen for high levels of contamination by lactic acid bacteria.

The AV-D-Lactic Acid kit is designed to measure D-Lactic Acid concentration, an important indicator of excess or unwanted growth of lactic acid bacteria. When winemaking is well controlled, these bacteria play an important role in improving wine quality, but when growth occurs at the wrong time or of the wrong species, wine quality and acceptability are greatly decreased. Regular monitoring can help prevent the development of lactic taint, biogenic amines, and bitter, "mousy," or "ropy" wines. The D-Lactic Acid kit has a range of 30 - 500 mg/L, equivalent to a range of 120 - 2000 mg/L with diluted samples.           D-Lactic Acid Quick Tests - Making Bacteria Contamination Monitoring Efficient for Everyone The D-Lactic Acid Test Kit includes 20 tests in a black barrier tube with a color chart label, 20 samplers, T20 dilution samplers, and how-to-run-a-dilution instructions.

The Residual Sugar Test Kit includes 20 tests, 20 samplers, and an insert with complete how-to-run test instructions.

Reducing sugars in wine consist of hexoses (mainly glucose and fructose) and pentoses (mainly arabinose and xylose). The pentoses can vary from 0.4 - 2.0 g/L; they are not fermentable by wine yeasts. Therefore, the best measure of primary fermentation is the determination of glucose and fructose.

The Quick Tests Residual Sugar Kit tests only for fructose and glucose sugars, the sugars reduced in primary fermentation. The test range is 100 - 2,000 mg/L.

The Free SO2 Kit includes 4 High Range Tests (red caps) and 16 Low Range Tests (green caps), 20 samplers, and an insert with complete how-to-run instructions.

Not all the sulfur dioxide present in must and wine is useful as a preservative. Some SO2 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 Quick Tests Free SO2 Kit includes a Low Range (0 - 40 ppm) and a High Range (40 - 130 ppm).
