FOR WINE, BEER & MEAD-MAKING - Fermaid O is a highly efficient yeast nutrient and rich source of more natural nitrogen. It’s used to achieve steady wine fermentations by compensating for deficiencies in nitrogen and micronutrients in the must...
HOW IT WORKS - Fermaid O aids yeast in producing less heat during fermentation compared to nutrients containing DAP. This minimizes heat spikes, resulting in fewer negative sulfur compounds and off-flavors in the wine. Additionally, it enhances ripe fruit...
EFFICIENT YEAST NUTRIENT - Fermaid O is an updated version of Fermaid K, notable for its absence of more natural nitrogen such as Diammonium phosphate (DAP) or ammonia salts. The more natural nitrogen it provides makes it easier for wine yeast to digest...
SUGGESTED USAGE - Recommended dosage is 1.5 grams per gallon of wine. Best if added in 2 doses: half at the end of the lag phase, and the other half once the sugar content is depleted by 1 ⁄ 3 of original gravity, calculated with a hydrometer. Before...
DRY YEAST – Create your best traditional wines with Lalvin K1-V1116 Wine Yeast. This strain is used to ferment grape wines or fruit wines, and is especially well-suited for making aromatic red, white, or sparkling wines.
QUALITY – This strain is a great choice for juices that are neutral or lack complexity on their own. This resilient yeast strain performs well in difficult fermentation conditions and extreme temperatures. K1-1V116’s alcohol tolerance allows you to...
QUICK FERMENTATION – This yeast strain has a short lag phase, meaning that fermentation is quick to start. Lalvin K1-V1116 Wine Yeast is known for producing high levels of floral esters. This strain performs best in a fermentation temperature range of...
HOME FERMENT INGREDIENTS – To begin fermentation, rehydrate yeast in 50 mL of water at a temperature of 95-98.6ºF. Gently stir to dissolve, then wait 20 minutes and add to the wine must. This packet of active dry yeast ferments a 1 to 6 gallon batch of...

Lalvin Bourgovin RC212 yeast was selected by the Bureau Interprofessionnel des Vins de Bourgogne, and was developed for red wines with color and structure
Main Material: The main components of yeast extract include polypeptides, amino acids, flavor-enhancing nucleotides, B vitamins, and trace elements
High-Tech Bioprocessing: Yeast extract is produced using modern high-tech biological techniques such as autolysis, enzymolysis, separation, and concentration. During this process, the proteins and nucleic acids within the yeast cells are degraded and...
Storage & Grade: This yeast extract powder should be stored at a temperature range of 2-30℃ to maintain its stability and optimal performance. It meets the FMB Grade standard, giving reliability and suitability for use in laboratory culturing, sample...
Widely Used: This culture medium is suitable for laboratory sample cultivation, molecular biology experiments, as well as basic teaching and research experiments

How to Choose the Best Winemaking Yeasts & Cultures
Understanding Yeast Types
Home winemaking yeasts can be broadly categorized by their origin and intended use. Wine yeasts are specifically cultivated for winemaking and offer predictable fermentation characteristics. They are classified by their tolerance to alcohol, temperature range, and their ability to produce or inhibit certain flavor compounds. For instance, some yeasts are known for producing fruity esters, while others are better suited for robust red wines.
Key Factors to Consider
Fermentation Characteristics: Look for yeasts that align with your desired wine style. Some yeasts are robust and can ferment quickly, while others offer slower, more controlled fermentations that can develop complex flavors.
Alcohol Tolerance: Ensure the yeast strain can handle the target alcohol by volume (ABV) of your wine. Higher alcohol tolerance is necessary for wines aiming for 12% ABV or more.
Flavor Profile: Yeast significantly influences the aroma and taste. Some strains enhance fruity notes, while others contribute to spicy or earthy characteristics. Research the specific flavor contributions of each strain.
Nutrient Requirements: Certain yeasts may require specific nutrients to ferment optimally. Check if the yeast packaging includes nutrient recommendations or if you need to purchase them separately.
Storage and Handling
Proper storage is essential to maintain yeast viability. Most winemaking yeasts are sold in dried form and should be stored in a cool, dry place, ideally refrigerated, to preserve their activity. Always check the expiration date before use. When ready to pitch, rehydrate the yeast according to the manufacturer's instructions, typically in warm water, to ensure a healthy and vigorous start to fermentation.
Frequently Asked Questions
What is the difference between wine yeast and bread yeast?
Wine yeast is specifically cultivated for winemaking, producing desirable alcohol levels and flavor profiles. Bread yeast, on the other hand, is designed for baking and can produce off-flavors and lower alcohol content in wine.
How do I know if my yeast is still active?
You can test yeast activity by rehydrating a small amount in warm water with a pinch of sugar. If it becomes foamy and bubbly within 15-30 minutes, it is active and ready for use.
Can I use the same yeast for red and white wines?
While some yeasts are versatile, specific strains are often recommended for red or white wines to best complement their unique characteristics. Using a strain suited for your wine type will yield superior results.
What is yeast nutrient and why is it important?
Yeast nutrient provides essential elements that yeast needs to ferment effectively, especially in fruit juices that may lack sufficient nitrogen. It helps ensure a complete and healthy fermentation, preventing stuck fermentation and off-flavors.
How long does winemaking yeast typically last?
When stored properly in a cool, dry place or refrigerated, unopened packets of dried wine yeast can last for 1-2 years. Once opened, it's best to use the yeast within a few months for optimal performance.
