Ideal for high nutrient-demand yeasts, it’s applied at the start and again at one-third sugar depletion, ensuring robust yeast health and accelerated fermentation. Compatible with Go-Ferm, it’s a must-have for professional and home brewers seeking consistent, high-quality results. ## Description Fermaid K is a blended yeast nutrient that supplies ammonia salts (DAP), free amino acids (organic nitrogen from deactivated yeast), sterols, unsaturated fatty acids, key nutrients (magnesium sulfate, thiamin, folic acid, niacin, biotin, calcium pantothenate) and inactive yeast. Add to must at the beginning of fermentation, and again at 1/3 sugar depletion for high nutrient requirement yeasts. Add at the rate of 1 grams per gallon. Fermaid K can be added directly to must, or if the fermentation is active, hydrate in water to avoid CO2 release and excessive foaming. Usage: 1 gram per gallon. Review: Super charge fermentation - Does an excellent job! I’ve added this Fermaid K to a couple gallons of must to brew Mead and in about 8 hours the fermentation took off in a supercharged style! I’ve attached a video of the active fermentation to prove it. At only 1 gram per gallon of must this stuff is definitely a “must”. Review: Great additive that does it's job well. - Straight up product with proven record. Fermaid K is what it is. This is the second time I've ordered this product and it's worked perfectly both times. ## Features - Complex yeast nutrient - 1 gram per gallon of must or juice - 80 g (2.8 oz) - Rehydrate in distilled water and add after 1/3 sugar depletion - Use with Go-Ferm for a complete yeast nutrition schedule ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B074DB7H5Z | | Best Sellers Rank | #258,399 in Grocery & Gourmet Food ( See Top 100 in Grocery & Gourmet Food ) #759 in Beer Brewing Ingredients | | Brand Name | CellarScience | | Container Type | Canister | | Customer Reviews | 4.7 4.7 out of 5 stars (268) | | Global Trade Identification Number | 00843200100190 | | Item Form | Powder | | Item Weight | 80 Grams | | Manufacturer | CellarScience | | Manufacturer Part Number | AD345B | | Material Features | Certified Organic | | Model Number | AD345B | | Number of Items | 1 | | UPC | 843200100190 | | Unit Count | 2.8 Ounce | ## Product Details - **Brand:** CellarScience - **Global Trade Identification Number:** 00843200100190 - **Item Form:** Powder - **Item Weight:** 80 Grams - **Manufacturer:** CellarScience - **Material Feature:** Certified Organic - **Number of Items:** 1 - **Package Information:** Canister - **UPC:** 843200100190 - **Unit Count:** 2.8 Ounce ## Images ![AD345B Fermaid K (80 g) - Image 1](https://m.media-amazon.com/images/I/41uabDBSxVL.jpg) ## Questions & Answers **Q: The description mentions organic nitrogen, does this mean this product could be called the 'O' version?** A: Fermaid O vs. Fermaid K has replaced the inorganic DAP (Diamonium phosphate) with an organic source. The manufacturer suggests it will result in lower heat output from the yeast, and lower levels of negative sulfur compounds. Straight DAP is like feeding your wine a "twinky" rather than a balanced diet. The organic compounds are consumed thus the "O" version you mention. I use it in whites, reds and fruits wines. Make the yeast happy and you'll make good wine. **Q: This works for meads? I make mead for celiac people, could i use this product?** A: Absolutely works for meades. In fact the staggered dose is the recommended method. **Q: Is this gluten free?** A: According to the manufacturer the product is Gluten free. **Q: How is this packaged? Small bag? small bottle?** A: Small bag, that you need to repackage into something after opening. i just used this and blended with go-ferm to make a blend ## Customer Reviews ### ⭐⭐⭐⭐⭐ Super charge fermentation *by C***S on December 6, 2020* Does an excellent job!
