Winemaking is full of options. One of the decisions that you will make during the process is: What additives, if any, should you add to your wine? While everyone has a different preference of taste, mouthfeel, color, etc., we have all of the additives you will need to impact those characteristics. Below are numerous different additives to add during the crush.
Wine Making Crush Additives

Potassium Metabisulfite
Potassium Metabisulfite, (often referred to as "SO2", "sulfites" "meta", or "meta-bi") has several uses in winemaking. At the crush, sulfites are generally used to help control the spoilage bacteria and indigenous yeast that may already be present both on the fruit and in the winery (i.e. on the picking bins, processing equipment, tanks, tubing, etc). The amount generally used is enough to inhibit most of the unwanted organisms but not enough to hinder a cultured yeast, which has a higher tolerance to sulfites than most of the indigenous organisms do. This inhibition effectively "wipes the slate clean" for the cultured yeast to step in and rapidly colonize the must so that it can effectively dominate the subsequent fermentation. In addition, sulfites also help to inhibit the enzymatic browning of both musts and finished wines so that all of their delicate complexities can be preserved. Later, during storage and in the bottle, sulfites at the proper levels will further protect a wine by continuing to inhibit spoilage organisms, as well as by scavenging oxygen. Note that the exact amount needed to effectively do the job is determined by the pH of the wine. 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. In addition, it's important to keep in mind that free SO2 levels fall faster in wood cooperage than in glass or stainless, so if you are using a barrel you will most likely need to manage sulfite levels more closely. The most common form of Metabisulfite is as a powder which is fixed with potassium or sodium. 1/4 tsp of Potassium Metabisulfite adds 50ppm to 5 gallons of must. Old Metabisulfite loses potency with time and should be replaced every year to assure that you are getting correct levels. You can use old Metabisulfite to make solutions for sanitizing equipment.

Lallemand Opti Red | For Color | Body | Tannin Integration
OptiRED – Lallemand Yeast Derivative for Color, Body & Tannin Integration in Red Wines Enhances early formation of polysaccharide–polyphenol complexes for more intense, stable color Rounds and smooths tannins to reduce harshness and astringency Builds fuller body and improved mouthfeel without altering varietal expression Can be used at the start or during fermentation for flexible control over tannin structure Outperforms generic inactivated yeast products by delivering high‑molecular‑weight mannoproteins via MEX™ processing OptiRED is a tailored inactivated yeast derivative produced by Lallemand using an innovative MEX™ method that makes high-molecular-weight polysaccharides immediately available in the must. When introduced early during maceration or alcohol fermentation, these compounds complex with freshly released anthocyanins and tannins, protecting color integrity and creating softer, more integrated tannin profiles. The result is a red wine with enhanced intensity, smoother palate, improved structural balance, and longer-term color stability—without over‑manipulating varietal character. This effect is particularly noticeable in light‑ to medium‑bodied reds or in vintages with lower phenolic maturity. Protocol Suspend the recommended dose in 10× its weight of clean must or water. Stir thoroughly to ensure full dispersion, then add at one of these points: • At the beginning of maceration or alcoholic fermentation for enhanced color protection and tannin integration • Toward the end of fermentation to smooth out persistent harshness without affecting initial extraction. Usage Rates Recommended dosage: 20–40 g per hectoliter = 0.2–0.4 g per liter = 0.76–1.5 g per gallon For standard use, 30 g/hL (0.3 g/L or ~1.14 g/gal) provides excellent balance between color enhancement and mouthfeel refinement. For home users a rough approximate of weight is 1 tsp = 2.6 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.

Lallzyme EX | Fermentation Enzyme for Early Drinking Red Wines
Specially formulated enzyme preparation for improved color intensity and stability, greater mouthfeel, and enhanced fruity, floral, spicy flavors in wine. Used primarily in red wines for the aforementioned reasons, it can also be used in white wines for increased extraction (however we recommend Lallzyme C-Max for whites because it helps the solids settle out as well). Based on the activity of a blend of cellulases, hemicellulases, and pectinases, this preparation aids in the extraction, then stabilization of water soluble phenols found in cells of grape skins. A dry, granular product requiring no special storage conditions prior to use. We have used this enzyme on our wine here at MoreWine and found the difference to be nothing short of amazing. Currently only available at MoreWine in this size! To use dissolve Lallzyme EX into a sufficient amount of water (usual ration is 1:100) and add to must with your other additions prior to the onset of fermentation. Dosage is 0.1g Lallzyme per gallon of must. Store dry enzyme at room temperature, around 25 C° (77 F°). Once rehydrated use within a few hours.

Tannin FT Rouge
This product replaces our TAN120 - Tannin VR Supra 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. How Fermentation Tannins Work Designed specifically for North American red wine fermentations, Scott'Tan FT Rouge is composed of exotic wood and chestnut tannins. These highly reactive tannins bind with anthocyanins (color compounds) in the first 3-4 days of fermentation. If sufficient natural tannins are not present in must, anthocyanins may precipitate, resulting in a loss of color. Using an enzyme like Lallzyme EX in conjunction with FT Rouge can enhance this binding of color. The continual bonding going on throughout the ferment will also improve the mid palate structure and help either significantly reduce or eliminate vegetal/herbaceous characters. Tannin additions at this early stage prove to be most efficient and are better integrated into the wine. Important!: If being used in conjunction with one another, tannins should be added 6-8 hours after the addition of the enzymes or you run the risk of having the tannins reacting with and removing the enzymes before they have had a chance to do their job!. To Use Sprinkle directly onto must and either mix well with your punch down tool or pump over to ensure thorough mixing. If adding to the wine post-fermentation we recommend allowing 3-6 weeks for full integration before racking, fining, filtering or bottling. Recommended dosage rate: 0.8-1.9 g/gal. Use at an initial rate of 1.3 gram per gallon during punch down/pump over. If you want additional tannin add at a rate of .25 g/gal. A rough approximate of weight is 1 tsp = 2.4 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. Unopened the shelf life is 5 years at 18ºC(65ºF).

Scottzyme KS | For Difficult Wines When Pec5L is Not Enough
cottzyme KS – High-Power Enzyme for Complex Pectin Breakdown in Red, White, and Problem Wines Breaks down complex, highly esterified pectins that standard pectinases cannot Enhances clarification, settling, and filterability in challenging juices and wines Boosts juice and wine yield by improving extraction from thick-skinned or high-pectin fruit Ideal for problem fermentations or hazy wines that resist fining and filtration Performs well at low temperatures and in a broad pH range Scottzyme KS is a specialized pectolytic enzyme designed to break down complex pectin structures found in high-pectin varietals and difficult ferments. While standard enzymes like PEC5L target simple soluble pectins, KS is formulated with enhanced side-chain cleaving activity that attacks esterified pectins and heavily branched structures. This makes it particularly effective on cultivars like Pinot Gris, Riesling, Gewürztraminer, Muscat, and in juice or wine where haze persists despite prior enzymatic treatment. KS improves clarification, tightens lees, increases press and wine yields, and boosts filtration efficiency—especially in wines that defy typical settling protocols. Comparison to Scottzyme PEC5L: Scottzyme PEC5L is a fast-acting general-purpose pectinase for typical clarification tasks, such as settling and flotation of white and rosé juices. It’s ideal for clean juice production from standard grapes and most fruit wines. In contrast, KS is the go-to choice when PEC5L isn’t enough—it’s stronger on stubborn, esterified pectins and delivers better results with problematic varieties or ferments that remain hazy even after PEC5L. While PEC5L is excellent for fast juice prep, KS excels in the most difficult cases, including post-fermentation haze and challenging press fractions. Protocol Dilute Scottzyme KS in 10 times its volume of chlorine-free water or juice. Add to must, juice, or wine and mix well. Suitable for use before or after fermentation. Do not add simultaneously with bentonite or high SO₂. Works effectively at 10–20°C. Usage Rates Recommended dosage: 1.5–4.0 mL per 1000 lb of fruit or 0.075–0.2 mL per gallon = approximately 0.02–0.05 mL per liter Use lower rates for moderate haze and extended contact time. Use higher rates in cold settling, high-pectin juices, or persistent post-fermentation hazes. Allow 4–24 hours of contact time depending on application.
