Wineries

A bottle of wine’s oxygen content has a great effect on its quality, stability, and longevity. Therefore, monitoring and controlling the oxygen incorporation at different stages of the winemaking and bottling process is becoming a growing concern for wineries. While dissolved oxygen is a part of the wine’s natural aging process, it can also be detrimental, causing oxidation that damages equipment and compromises product. Wine Producers maintain low DO content to prevent oxidation, loss of aroma, discoloration, rapid aging, and the growth of microorganisms. Read more about dissolved oxygen: Here

Titrators have multiple use in the wine industry. Acidity, for example, has an impact on taste and is an indicator of product quality. The titrator determines here pH and Total Acidity.

• Acid titrations measure wine's acidity, important for flavor and stability. Total acidity is commonly measured, combining tartaric, malic, and citric acid levels.
• SO2 titrations measure SO2 levels in wine, commonly used preservative to prevent oxidation and microbial growth. It ensures safe and legal limits of free and total SO2 concentrations.
• Alkalinity titrations: Titrations can be used to measure the alkalinity of water used in winemaking. High alkalinity can affect the pH of the wine and lead to undesirable flavors.
• Sugar titrations: Titration methods can be used to measure the sugar content of wine, which is important for determining the wine's final alcohol content.

Users of Hach AT1000 are not in direct contact with reagents. In addition, AT1000 titration methods do not use potentially dangerous color indicators, e.g., Phenolphthalein (CMR classified). The titrator AT1000 from Hach provides the ability to measure other additional parameters with one device, including Alkalinity (TA/TAC), Salt, and Free & Total SO₂ in wines.

Most common practice in wineries to measure turbidity is with a portable or benchtop turbidimeter. All turbidimeters have different operating requirements, so it is important to check the instructions before use.

Nonetheless, most turbidimeters follow the same general procedure for benchtop or portable units:

1. Uncap a clean vial and fill it with the unfiltered water sample you wish to measure. Be sure to stir the sample by inverting the container before pouring it into the measurement cell to kick up particles that may have settled, but without creating air bubbles.
2. Tighten the cap on the sample cell (or measurement cell) and hold it by the cap.
3. Wipe away any excess liquid, dirt, or finger markings from the cell with a soft lint-free cloth before measuring.
4. Place the turbidimeter on a flat surface.
5. Turn on the device.
6. Set the automatic range.
7. Select signal averaging.
8. Put the cell into the measurement compartment of the turbidimeter.
9. Close the compartment lid.
10. Select the “Read” button, which should give you a measurement in NTU

Turbidimeters, also called turbidity meters, are instruments used for measuring the turbidity of liquids. The turbidity of a sample is proportional to the intensity of the light reflected by particles in the water.

A portable turbidimeter is a handheld device used to measure the turbidity, or the degree to which water loses its transparency due to the presence of suspended particles, in a liquid sample. It typically consists of a light source that shines light through the sample and a detector that measures the amount of light scattered by the suspended particles. Portable turbidimeters offer convenient measurements in the field, throughout your production plant and are commonly used in water treatment plants, laboratories, and field settings to monitor the quality of drinking water, wastewater, and other liquids, such as soft drinks, wine and other alcoholic beverages.
