Not sure what bung is right for you? We got your back! Get all the Breathable Bungs with this complete set. Includes: Breathable Carboy Bung Breathable Universal Bung Breathable Barrel Bung Breathable Bung for Glass Carboys A breathable Silicone stopper that acts as both a stopper and an airlock. Unique design allows CO2 pressure to escape but keeps Oxygen and airborne contamination out. This quickly became our stopper of choice for wine, and is a popular style used by numerous commercial wineries. Also has great application for beer ferments: It will create a vacuum if fermenting wort cools (as opposed to pulling water in from your traditional airlock.) Airtight seal is great for extended fermented lager when CO2 production is still present but very slight. Fits 3, 5, 6 & 6.5 gallon glass carboys, 1 gallon bottles, growlers, and 500 mL flasks. Replaces Stopper Sizes #6, #6.5, #7, #8 Stopper Measurements: 0.94" x 1.48" (24 mm x 37.5 mm) Universal Breathable Bung This CellarScience Bung has a ridge to keep it from getting sucked in and self-sealing vent holes to let air out but not in. They have a gentle taper, so they don’t slip out during use. They are also very easy to clean and sanitize. This a perfect fit for a 1.5” TC ferrules, Fermonsters, and Vintage Shop Plastic carboys. Replaces Stopper Sizes #8, #9. #10 Stopper Measurements: 1.36" x 1.89" (34.5 mm x 48 mm) Breathable Barrel Bung We recently discovered this premium breathable silicone barrel bung and were immediately impressed with its robust design and features. To start with, the ridge really helps make bung removal effortless. The bung acts as an airlock and allows the release of CO2 while maintaining a seal against oxygen coming in. This makes the bung ideal for alcoholic or malolactic fermentation in barrels or tanks. Fits 30- and 60-gallon barrels as well as the hole in the lid of most Variable Volume tanks! Also fits perfectly in a 2" tri-clamp ferrule Replaces Stopper Sizes #10 , #11, #12 Stopper Measurements: 1.65" x 2.19" (42 mm x 55.5 mm) The flapper stopper protrudes roughly 2.5" from the stopper

The ideal yeast for producing a very neutral, clean base for hard seltzers, canned cocktails, further distillation, etc. Works with malt or sugar fermentations Includes nutrients and pH buffers to keep fermentation humming to finish Able to handle high levels of ethanol and osmotic pressure Ferments clean up to 80°F ​Our motto is to Empower Your Creative Vision. Origin is a unique style of yeast used to create a neutral alcoholic base that acts as the Origin upon which you layer other flavors. Perfect for Hard Seltzers, Canned Cocktails, and whatever else you can dream up. Also great for neutral washes designed for distillation and tough to ferment honey-based mead fermentations. Works on both sugar, honey, and malt-based fermentations. The secret sauce is a very neutral, high alcohol tolerant yeast combined with nutrients and pH buffers. The non-urea-based nutrients help the yeast in simple sugar mediums naturally low in nutrients. pH buffers ensure a high enough pH to allow the yeast to run to completion in even the toughest of situations. The yeast strain used in Origin is a very low producer of H2S and fruity esters resulting in a clean final product. Origin stays clean at higher fermentation temperatures up to 80°F. Origin could technically be called a Turbo Yeast being packed with nutrients. However, we don't like that association as many turbo Yeasts are not selected and assembled for quality and flavor but rather price and speed. Turbo Yeasts also do not include pH buffers. Origin will work with all commonly used sugars, including sucrose, dextrose, and liquid invert sugar. When fermenting wort from malted barley, use our Brutzyme Glucoamylase Enzyme to break down α-1,4 and α-1,6 glycosidic linkages of starch, dextrins, and oligosaccharides for a drier, more fully attenuated final product. Pilot batches should always be performed to find the optimum final product for your further vision. Directions: Add 10 to 20 g per gal (2.5 to 5 g per liter) directly into your fermentation with no hydration required. Ferment between 65 to 80°F (18-27°C). We recommend starting with a dosage of 15 g per gal (4 g per liter) and adjusting as desired in future batches.
