  • Erlenmeyer Flask - 2000 ml

    Erlenmeyer Flask (2000 ml)

    65 reviews

    The perfect container for rehydrating yeast or mixing up additions. Erlenmeyer flasks allow you to swirl your yeast or acid, tannins, nutrients, etc. into solution. The clear glass allows you to see when the solution is fully mixed. In the lab world, these are known as "Student Grade" Made from Borosilicate glass, it can be rapidly heated or cooled without the risk of cracking. Recommended Process for Use of Flask: Double Boiler Method It is important for your safety to heat water in the flask with a heat source that distributes heat evenly. Our manufacturer has confirmed that direct heat to the glass can break down its integrity and break if the heat source doesn't distribute evenly.  Morebeer! recommends using the "double boiler method."  This process involves using a boiling water bath on the outside of the flask to heat up the water inside the flask.  All you need is a kettle 3 gallons or larger.  This process is much safer and efficient. If the flask should break or boil over, your kettle will be there to collect the contents, thus keeping your stove clean and keeping you away from potential harm.   Features Massive 2L (2000ML) Capacity Made from Borosilicate Glass Fantastic price for a flask of this size Produced for MoreWine!

  • Hanna Digital Refractometer (HI 96811)

    Hanna Digital Refractometer (HI 96811)

    13 reviews

    The HI96811 is a rugged, portable digital refractometer designed for sugar measurement of juice and must. The HI96811 reports sugar content as % Brix and has a high accuracy of ±0.2%. The operation of the meter is simplified with only two buttons: one button is to calibrate with distilled or deionized water and the other to take a measurement. All readings are automatically compensated for temperature variations according to the ICUMSA Methods Book standard and displayed within a 1.5 second response time. The sealed flint glass prism and stainless steel well are easy to clean. Just wipe with a soft cloth in preparation for the next sample. Sample size as small as 2 metric drops (100 μl) Sealed stainless steel well with high-grade optical prism made of flint glass Fast 1.5 second response time for temperature compensated readings The HI96811 Digital Refractometer converts the refractive index of a juice or must sample to % Brix. This conversion is based on the tables found in the ICUMSA Methods Book (International Commission for Uniform Methods of Sugar Analysis) that documents the changes in the refractive index with temperature for a percent by weight sucrose solution. Since the majority of sugar in grape juice and must is fructose and glucose instead of sucrose, the reading is sometimes referred to as “Apparent Brix”. Typical grapes at harvest will be between 19-24% Brix or degrees Brix (°Bx). The HI96811 is an easy-to-use tool for winemakers for measuring sugar in grapes or must, in the field or in the lab. Designed for winemaking sugar analysis Temperature Compensation algorithms based on sucrose solution 0 to 50% Brix range with an accuracy of +/- 0.2% Brix Making a Standard % Brix (Sucrose) Solution To make a Brix Solution, follow the procedure below: Place container (such as a glass vial or dropper bottle that has a cover) on an analytical balance. Tare the balance. Weigh out X grams of high purity sucrose (CAS #: 57-50-1) directly into a beaker. Add distilled or deionized water to the beaker so the total weight of the solution is 100g. Note: Solutions above 65% may need to be vigorously stirred or shaken and heated in a water bath to roughly 40°C (104°F). Remove solution when sucrose has dissolved and allow to cool before use. Refractive Index The HI96811 takes measurements based on a sample’s refractive index. The refractive index is a measurement of how light behaves as it passes through the sample. Depending on the sample’s composition, the light will refract and reflect differently. By measuring this activity with a linear image sensor, the sample’s refractive index can be assessed and used to determine its physical properties such as concentration and density. In addition to the linear image sensor, the HI96811 uses an LED light, prism and lens to make measurement possible. Variations in temperature will affect the accuracy of refractometry readings, so the use of temperature compensation is highly recommended for reliable results. The HI96811 contains a built-in temperature sensor and is programmed with temperature compensation algorithms in accordance with the ICUMSA Methods Book Standard for a percent by weight sucrose solution. Features-at-a-glance One-point calibration - Calibrate with distilled or deionized water Small sample size - Sample size can be as small as 2 metric drops (100 μl) Quick, accurate results - Readings are displayed in approximately 1.5 seconds Dual-level LCD - The dual-level LCD displays % Brix and temperature readings simultaneously Battery indicators - Battery percent level remaining at startup and low battery indicator Automatic shut-off - To conserve battery life the meter shuts off automatically after three minutes of non-use Stainless steel sample well - Easy to clean and corrosion-resistant IP65 water-resistant protection - Water resistant ABS plastic casing designed to perform under laboratory and field conditions.

    The New EasyDens by Anton Paar

    27 reviews

    The EasyDens from Anton Paar was developed as a digital gravity/alcohol tester for small commercial breweries, but this product is just as useful in the winemaking process—from measuring and tracking the sugar content of grapes in the field to measuring alcohol levels at the end of fermentation. With only a small sample being needed, the EasyDens eliminates the need to fill up a hydrometer jar or using a refractometer and spread sheet to determine your test results. A tiny 2 ml sample is all that you need for an accurate Brix reading. Alcohol % can also be tracked at any point during fermentation. The unit hooks up to your smartphone via Bluetooth and stores various fermentation "profiles" enabling you to track fermentation progress, alcohol levels, and help know when it's time to bottle your wine! Brix Measurements Range: -10 °Brix to 80 °Brix Accuracy: 0.3 °Brix Resolution: 0.1 °Brix In order to get accurate measurements, please note your sample will need to have the solids filtered out and degassed prior to taking measurements.

  • Acid Reagent for MT693 - 230mL (Hanna# HI 84500-60)

    Hanna Acid Reagent for Titrator - 230mL (Hanna# HI 84500-60)

    The HI84500-60 is a 230 mL bottle of acid reagent required for both low and high range determinations of sulfur dioxide in wine using the HI84500 Sulfur Dioxide Mini Titrator for Wine Analysis. The acid reagent is used to lower the pH value of the sample prior to performing a titration. With 5 mL of reagent required per test, there is enough acid reagent for approximately 46 tests. Pre-measured solution Clearly marked expiration date and lot number Air tight bottle with tamper-proof seal to ensure quality The HI84500-60 acid reagent is necessary to lower the pH of the wine sample before a titration can be performed for either free or total sulfur dioxide. The adjustment of the wine sample with 5 mL of the acidic reagent ensures the sample is at the correct pH. The addition of HI84500-62 stabilizing powder is also added prior to performing the titration. The HI3148B ORP electrode is used to detect the endpoint for both the low (1.0 to 40.0 ppm of SO2) and high (30 to 400 ppm of SO2) ranges. The HI84500 can be used with all wines, including red, which are difficult to test using traditional methods due to the difficulty to observe a distinctive color change when the endpoint is reached.   The HI84500 determines the free and total sulfur dioxide concentration in wine using the Ripper method. Excess iodide is added to the wine sample and reacts with the iodate titrant to produce iodine:   IO3- + 5I- + 6H+ → 3I2 + 3H2O   The iodine produced reacts with sulfur dioxide in the wine according to the redox reaction below:   H2SO3 + I2 → H2SO4 + 2HI   Replacement reagents required to operate the HI84500 include:     Low Range - 1.0 to 40.0 ppm SO2 High Range - 30 to 400 ppm SO2 Pump calibration standard HI84500-55 HI84500-55 Titrant solution HI84500-50 HI84500-51 Acid reagent HI84500-60 HI84500-60 Alkaline reagent (Total SO2) HI84500-61 HI84500-61 Stabilizer powder packets HI84500-62 HI84500-62 Requires only 5mL per test Pre-measured solution with clearly marked expiration date and lot numbers in a tamper proof bottle, can be utilized for all wines including red.

  • Stabilizer Packets for MT693 - 100ct (Hanna# HI 84500-62)

    Stabilizer Powder Packets for Sulfur Dioxide Mini Titrator - 100 Packets (Hanna# HI84500-62)

    The HI84500-62 are packets of stabilizer reagent required for determination of sulfur dioxide in wine using the HI84500 Sulfur Dioxide Mini Titrator for Wine Analysis. The HI84500 mini titrator uses two different titrant solutions that contain different concentrations of potassium iodate to measure a wide range of sulfur dioxide concentration in wine. Both low and high range measurements require the addition of HI84500-62 stabilizer powder to convert iodate into iodine, which in turn reacts with sulfur dioxide. The HI84500-62 powder is packaged into single use packets that are emptied into the sample prior to performing the titration. Pre-measured packets Clearly marked expiration date and lot number The HI84500-62 stabilizer powder packets are necessary to convert the iodate titrant into iodine. The iodine then reacts with sulfur dioxide and the HI3148B ORP electrode is used to detect the endpoint for both the low (1.0 to 40.0 ppm of SO2) and high (30 to 400 ppm of SO2) ranges. The decision by Hanna to use the HI84500-62 stabilizer powder packets and iodate titrant in place of a iodine titrant is due to shelf stability. Iodate offers much greater shelf stability than iodine. By using stabilizer packets the titrant solutions remain stable for longer periods of time.The HI84500 can be used with all wines, including red, which are difficult to test using traditional methods due to the difficulty to observe a distinctive color change when the endpoint is reached.   The HI84500 determines the free and total sulfur dioxide concentration in wine using the Ripper method.

Throughout the entire winemaking process it's important to test our wines to make sure they are healthy and are progressing as we would like. MoreWine! highly recommends testing wine for the following:

  • TA testing measures the amount of total acids in the wine or must.
  • pH testing gives you an idea of how the wines acidity will be perceived when we drink it. A pH measurement is done using a special meter that measures the relative balance of the acidity as it relates to the buffers (mostly Potassium) naturally found in a wine or must.
  • Sugar testing is done to measure the amount of sugar in a wine or must. This amount is important to know because wines that contain residual sugar (not "dry") need to be stabilized before being bottled or you may have spoilage and re-fermentation problems later in the wines' life.
  • SO2 testing is a critical tool to being able to properly protect your wine from oxidation and spoilage organisms. SO2 levels should be properly maintained throughout the entire ageing period right up until the wine is bottled. (Complete information on SO2 management can be found in our SO2 Management Paper!)
  • Malolactic Chromatography testing is used to monitor the completion (or presence of) of malolactic fermentation in the wine. Any wine that has residual malic acid is considered unstable and will need to be stabilized correctly before being bottled or you run the risk of possible renewed fermentation after the wine is in the bottle which spoils the wine.
  • Temperature testing is important at all stages of winemaking: from helping make sure fermentation temperatures don't get too hot, to maintaining the recommended ageing/storage temperatures that will ensure the best development of your wine!

Complete information on testing wine can be found in our Red Winemaking manual, our White Winemaking Manual and in the MoreWine! MoreManuals section of our website!
