Measuring & Testing Wine

Used in conjuction with the pH function of either your SC-200 or SC-300 Analyzer, the Yeast Assimilable Nitrogen (YAN) test from Vinmetrica measures the combination of amino acids, ammonium ions, and small peptides. YAN is important as it can contribute to sluggish fermentations and off flavors in your wine. Specifications: Measures down to 20 mg/L of available nitrogen with accuracy of 10 mg/L of available nitrogen. Enough for 25 tests (only $1.28 per test!) 1 year shelf life Includes: YAN Reagent (37% Formaldehyde/15% methanol, Part Number SC-200-14-1) YAN Formaldehyde Neutralizer Powder (Sulfite, Part Number SC-200-14-2) Three Plastic Transfer Pipettes (SC-100-5)

In wine, used to suppress naturally occurring microorganisms and prevent spoilage. Also works as an antioxidant. Add at a rate of 1 tab/gallon to achieve 75 ppm free SO2.  These tablets use potassium metabisulphate as opposed to sodium metabisulphate.  Potassium based campden tablets are generally preferred by winemakers who do not want to add excess sodium into their wine.   Can also be added to water to remove chloramine (1 tab is sufficient for roughly 5-20 gallons)

Safety Bulb pipette filler for use with solutions that should not be mouth pipetted. In general, it is best to use the filler with anything that is not a wine sample.To Use: Squeeze filler and place on top of the pipette. Place the pipette in the solution, allowing the bulb to re-expand, drawing liquid into the pipette. Draw liquid up past the point in the pipette that you would like it filled to. Now, being careful not to draw up excess liquid or squeeze out what you have in the pipette, quickly remove the squeeze bulb and place your index finger tightly over the top of the pipette. Now by gently lifting your finger, you can allow the liquid to run out to the level that you're looking for.**Tip:** Be careful not to draw your liquid up into the filler. Many chemicals that are used around the lab can degrade the filler and cause poor sealing, making the filler harder to use. A great way to get a feel for the tool is to practice for a little while with some water, until you can easily remove the filler and seal the pipette with your finger.

Good for measuring lactic acid and other chemical solutions in small quantities. This glass pipet is designed as To-Deliver, not To-Contain, meaning that you do not want to blow out the last little bit in the tip after the sample drains out or you will deliver more than your measured amount.

The SC-300 Pro Kit has everything the normal SC-300 has plus these accessories: The Lab Support Stand Vinmetrica Electrode Holder The Double Burette Clamp Magnetic Stirrer Rinse Bottle A Small Tube of Burette Detergent 25 mL Glass Burette. The Ultimate Winemaker’s Companion shipped free from MoreWine! One lean, mean wine analyzing machine. The SC-300 combines the SO2 detection of the SC-100A and the pH/TA analysis of the SC-200 into one power-packed instrument. It’s built on the same hardware and software as our other two analyzers, so the accuracy is superb. And it’s just as easy to use – The audible buzzer and visual stop light will automatically let you know when you’re tests are done! Because it does not rely on a color change, the SC-300 eliminates the guesswork in Ripper sulfite tests, especially in red wines! Why Choose Vinmetrica’s SC-300? Where else will you find a single, compact instrument that can measure sulfite (SO2), pH and TA (Titratable Acidity) levels throughout the fermentation and aging process? Even in Red Wines! It’s Accurate: SO2: ± 2 ppm Free SO2. TA: ± 0.2 g/L Tartaric acid pH: better than ± 0.02 pH units Quick! – Less than 2 minutes per test! Affordable – About a $1 per test!* Easy to Use – No mystery solutions, pumps or tubing. *SO2 (Sulfite) Tests cost approximately 70¢ / Test (the cost of the reagents per test). If you do a combined pH and TA analysis, the cost of reagents for the pH/TA test is approximately $1.12 / Test. Complete Wine Testing Kit – Includes Everything Needed to Analyze Sulfite (SO2), pH and TA (Titratable Acidity) levels in Your Wines & Musts: SO2 reagents pH/TA reagents Two titration beakers Two 5 mL syringes Two transfer pipettes SO2 electrode pH electrode 25 mL sampling pipette (for SO2) 5 mL sampling pipette (for pH/TA) The SC-300 Operating Manual The SC-300 analyzer gives accurate SO2, pH and TA values. Kit includes everything to perform about 50 sulfite tests and 30 TA tests: both electrodes, all reagents, pipettes, syringe and beaker. A Quick Overview – Wine Analysis Procedures with the SC-300: Easy SO2 Test Attach SO2 electrode, press the power button, change to SO2 mode and press enter. Draw up 5 mL of titrant into the syringe and place 25 mL of wine in beaker. Add ~2 mL of the acidifier and ~2 mL of the reactant to wine. Place and hold the SO2 electrode in the wine sample and swirl beaker. Add titrant from syringe dropwise until 15 second long endpoint signal reached. Multiply the titration volume by 20, the SO2 conversion factor, results in ppm Free SO2. Simple pH Test Attach the pH electrode, set aside storage solution, rinse with DI water and blot gently with a paper towel. Press the power button then press the ‘Mode’ button and switch the SC-200 into ‘Cal’ mode. Calibrate using the pH 4 and pH 7 reference standards provided. Put the SC-200 in pH mode. Take 5 mL sample of wine, place in a beaker. Take a pH reading. Accurate TA Test For TA test, withdraw 5 mL of the TA Titrant with the syringe. Take 5 mL wine sample and add ~15 mL of deionized water. Put SC-200 into TA mode, place clean pH electrode gently in solution. Add TA Titrant from the syringe dropwise until the endpoint is reached indicated with the visual and audible signals. Record the volume (in mL) of titrant used. Multiply the titrantion volume by 2, the TA conversion factor, results in g/L Tartaric Acid. Vinmetrica Troubleshooting Guide

Ascorbic acid is a quick-acting and powerful antioxidant that is used in white winemaking to protect against light and short aerations, such as racking and bottling. It works by rapidly converting dissolved oxygen into hydrogen peroxide before it has a chance to react with oxidative enzymes and cause browning. However, this hydrogen peroxide itself needs to be removed from the wine in order to avoid the very phenomenon that was trying to be avoided in the first place, namely oxidizing the wine. The answer lies in always making sure that the free SO2 levels are correct, both before the ascorbic addition is to be made and after. (Note that "Titrettes" are not accurate enough for this, and that a more precise means of determing free SO2 is needed, such as an Aeration-Oxidation set-up). Addition rate is around 50 mg/l (ppm) as long as the free SO2 is maintained at 30 mg/l (ppm). A rough approximate of weight is 1 tsp = 3.2 grams. We highly recommend using a scale to weigh the product for an accurate dose. We do not recommend relying on these rough conversions for accurate dosage rates.
