Feed your fermentation with FermFed DAP Free by CellarScience®. The 100% natural formulation of FermFed DAP Free is derived from the autolysis of very specific yeast strains naturally high in free amino acids, sterols, mannoproteins, zinc, magnesium, and niacin, along with vitamins B1, B2, B5, B6, and B12 for a complete yeast health regimen.  As the name suggests, this unique formulation does not contain the traditional inorganic diammonium phosphate, but does provide organically derived nitrogen. How Much Do I Add and When? The recommendation that covers most fermentations is to add 1.5 gram per gallon of FermFed DAP Free at the onset of fermentation and then add 1 gram per gallon of FermFed after 1/3 sugar depletion. Mix the nutrients in a small slurry of water and add to the fermentation.  Read more below if you are interested in measuring YAN (Yeast Available Nitrogen) and adjusting your nutrient schedule accordingly.   The Science of How it Works The different components of FermFed DAP Free work in different ways to feed and protect your yeast.   The complex and organic nitrogen in FermFed DAP Free helps eliminate excessive yeast growth in the initial phases, reducing fermentation heat spikes at the start of fermentation. Included sterols make the yeast membrane more resistant to alcohol and to high temperatures.  The collection of B-vitamins along with zinc and magnesium are essential for enzymatic activity, alcohol tolerance, and yeast health.  Mannoproteins help avoid the aromatic stripping during the fermentation by binding esters and terpenes and not allowing them to be driven off by CO2.  The included yeast hull components act as receptors to bind up fatty acids that can accumulate and cause stuck fermentations. Advanced - Adjusting Your Nutrient Schedule Based on YAN (Yeast Available Nitrogen) In addition to the nutrients provided by FermFed or FermFed DAP Free, yeast need a certain level of nitrogen to perform adequately. If deprived of nitrogen, yeast are more likely to produce off flavors, most notably hydrogen sulfide. When added at the rate of 1 gram per gallon, FermFed provides 38ppm of YAN while FermFed DAP Free adds 20ppm when added at the rate of 1.5 gram per gallon.    How much YAN do you need? Acceptable levels range from 175 to 300ppm.  YAN levels in grapes vary, with grapes from warmer climates often having less. The best practice is to measure your grapes using a commercial wine lab or the Vinmetrica YAN Test Kit along with a Vinmetrica Meter. If you know your YAN the following is a good general guide: 175ppm or above = FermFed DAP Free @ onset + FermFed DAP Free @ 1/3 completion (adds 40ppm YAN) 150ppm or above = FermFed DAP Free @ onset + FermFed @ 1/3 completion (adds 58ppm YAN) 125ppm or above = FermFed @ onset + FermFed @ 1/3 completion (adds 72ppm YAN) Below 125ppm = FermFed @ onset + FermFed @ 1/3 completion + extra DAP    For a full yeast nutritional plan, use FermStart when rehydrating your yeast, use FermFed DAP Free at the onset of fermentation, and use FermFed after 1/3 sugar depletion.

An essential ingredient in winemaking.   Sodium Metabisulfite, (often referred to as SO2, sulfites meta, or meta-bi) has several uses in winemaking. It is used at the crush, to help control the spoilage bacteria and indigenous yeast that may already be present on the fruit or the equipment. The amount used is enough to stop most of the unwanted organisms but not enough to hinder a cultured yeast, which has a higher tolerance to sulfites. This effectively “wipes the slate clean” for the cultured yeast to step in and rapidly colonize the must.   Sulfites also help to inhibit the enzymatic browning of musts and finished wines. During storage and in the bottle, sulfites at the proper levels will protect a wine by continuing to inhibit spoilage organisms, as well as by scavenging oxygen.   Campden tablets are Sodium Metabisulfite in an easier to measure format. Adds 75 ppm of sulfites at the rate of one tablet per gallon. These must be fully ground-up prior to use. Potassium Meta-bi in powder form, AD495 or AD500, is much easier to use if you have a scale and does not add sodium to your wine.   It is possible the sodium could contribute a very small salty flavor. Especially when making white wine it is preferable to add potassium over sodium since added potassium can later help with cold stabilization.   For more information refer to our MoreManuals! on Red or White Winemaking or one of the winemaking books that we offer for a complete explanation on how to properly manage sulfites.

This product replaces our TAN140 - Tannin Plus Enological tannins offer the winemaker the possibility to add refined, highly-bindable tannin to your wine at any stage during the process. Benefits can include increased structure and mouthfeel, color stabilization, stability, anti-oxidative qualities, and overall complexity. Tannins can reduce vegetal/herbaceous characteristics and perceived astringency. We offer four types of oenolgical tannins, two for use during fermentation, and two for use during the aging phase. Aging Tannins Tannin Riche Extra is a preparation of 100% American oak tannin that has been lightly toasted to impart a soft, aromatic character while enhancing the structure and organoleptic complexity of a wine. Tannin Riche Extra is a great tool for imparting hints of coconut, a heightened vanillin oak character and a smooth finish to your wines. Although designed for fine-tuning a wine, Tannin Riche Extra still maintains the regular properties associated with the use of tannins such as helping with clarification, stability, oxidation, and aging. Works well in conjunction with low doses of other tannins (i.e: Tannin Complex & FT Blanc Soft). To Use: Dissolve the tannin in 10 times its weight in warm water (95F/35C). Add to the wine during a punch-down or pump-over for good mixing. Addition of Tannin Plus should be made a minimum of three weeks before bottling. Recommended dosage: 0.2-0.4 g/gal A rough approximate of weight is 3/4 tsp = 1 gram. 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.

Help your yeast reach the end of fermentation safely while producing amazing flavors with FermFed by CellarScience®.  Yeast that are given FermFed have a higher likelihood of fermenting without issue while producing wines with more intense flavors and aromas.  FermFed is a complex nutrient blend of diammonium phosphate, thiamin, amino acids, sterols, pantothenic acid, mannoproteins, protective microelements derived from yeast hulls, and vitamins B2, B5, B6, & B12.  FermFed also contains the organic and inorganic nitrogen (DAP) that yeast need.     How Much Do I Add and When? The recommendation that covers most fermentations is to add 1 gram per gallon of FermFed DAP Free at the onset of fermentation and then add 1 gram per gallon of FermFed after 1/3 sugar depletion. Mix the nutrients in a small slurry of water and add to the fermentation.  Read more below if you are interested in measuring YAN (Yeast Available Nitrogen) and adjusting your nutrient schedule accordingly.     The Science of How it Works The different components of FermFed work in different ways to feed and protect your yeast.  Grape must/juice is often deficient in assimilable nitrogen. When yeast do not have enough nitrogen, they are more likely to produce hydrogen sulfide (rotten eggs). FermFed helps to eliminate this problem by providing enough nitrogen for most situations.    Yeast get weaker as they divide and multiply. They run the risk of not being able to properly finish fermentation as the alcohol content rises. Feeding them sterols help cells maintain membrane fluidity so that the yeast can properly function as alcohol and other harmful compounds in the fermentation conspire against them.   Mannoprotein molecules bind esters and terpenes and work as an anchor to keep them in solution so they are not driven off by CO2 during fermentation.  Pantothenic acid is added to help reduce the production of hydrogen sulfide.   Thiamine is important for yeast metabolism.  Vitamins B2, B5, B6, & B12 are important for general yeast health.    Advanced - Adjusting Your Nutrient Schedule Based on YAN (Yeast Available Nitrogen) In addition to the nutrients provided by FermFed or FermFed DAP Free, yeast need a certain level of nitrogen to perform adequately. If deprived of nitrogen, yeast are more likely to produce off flavors, most notably hydrogen sulfide. When added at the rate of 1 gram per gallon, FermFed provides 38ppm of YAN while FermFed DAP Free adds 20ppm.    How much YAN do you need? Acceptable levels range from 175 to 300ppm.  YAN levels in grapes vary, with grapes from warmer climates often having less. The best practice is to measure your grapes using a commercial wine lab or the Vinmetrica YAN Test Kit along with a Vinmetrica Meter. If you know your YAN the following is a good general guide: 175ppm or above = FermFed DAP Free @ onset + FermFed DAP Free @ 1/3 completion (adds 40ppm YAN) 150ppm or above = FermFed DAP Free @ onset + FermFed @ 1/3 completion (adds 58ppm YAN) 125ppm or above = FermFed @ onset + FermFed @ 1/3 completion (adds 72ppm YAN) Below 125ppm = FermFed @ onset + FermFed @ 1/3 completion + extra DAP    The best way for to test for YAN is using a lab or a home testing solution like this YAN kit from Vinmetrica. An acceptable level for YAN is between 200 to 350ppm FermFed provides 38ppm of Yan when added at the rate of 1 gram per gallon. The reason we don’t automatically use FermFed for a Stage 2 is that we don’t want to introduce excessive amounts of DAP into the wine if your yeast don’t need it.     For a full yeast nutritional plan, use FermStart when rehydrating your yeast, use FermFed DAP Free at the onset of fermentation, and use FermFed after 1/3 sugar depletion.

Wine Making Use Delvozyme (Lysozyme, Lysovin) for controlling lactic acid bacteria growth in your wine. Isolated from egg whites, this enzyme will degrade the cell wall of gram positive bacteria, but will not affect yeast or gram negative bacteria such as Acetobacter. Delvozyme can be used for both Red and White Wine Malo Fermentation. Dosage: To Delay Malolactic Fermentation: Red Wine - add to grapes at 100 - 200 ppm, or 0.38 - 0.76 grams per gallon. White Wine - Add to must at 200 - 300 ppm, or 0.76 - 1.14 grams per gallon. To Block Malolactic Fermentation: White Wine - Add to must or wine at 300 - 500 ppm, or 1.14 - 1.90 grams per gallon. Stabilizing wine after MLF is complete: Add to barrel during storage at 250 - 500 ppm, or 0.95 - 1.90 grams per gallon. When blending partial and complete MLF wines: Add immeditatley after blending at 300 - 500 ppm, or 1.14 - 1.90 grams per gallon, to reduce the risk of further malolactic fermentation (MLF). Within several days any lactic should expire. For sluggish or stuck yeast fermentation: Red Wine - Add at 150 - 400 ppm, or 0.57 - 1.52 grams per gallon. White Wine - add at 300 - 500 ppm, or 1.14 - 1.90 grams per gallon. Directions for use: You can make a 10% solution of Delvozyme in water (100 grams per liter of water). However we find the easiest method is to add the desired dry weight of Lysovin in 5x its weight of warm(tepid) water. Mix for one minute, allow this mixture to stand for 45 minutes and add to must, juice or wine while mixing well. Allow 24 - 48 hours for reaction to complete. **Note: 3tsp Delvozyme = 5g Beer Making Delvozyme can be used in beer making as well. Use either in the starter (recommended if you make starters) or when pitching (adding) the yeast to the wort, do not use over 140 F. Recommended dosages is 1 tsp per 5 gallons of wort. According to studies it has no effect on flavor or clarity. Storage: Should be stored at room temperatures in a dry environment, can be stored up to 5 years.
