It is a high-molecular-weight tannic acid product designed for brewers who want to reduce haze-active proteins, bind iron, and improve flavor stability as part of a controlled mash or kettle process.\u003c\/p\u003e\n\n\u003ch3\u003eWhat BrewTan B does\u003c\/h3\u003e\n\u003cp\u003eBrewTan B reacts with haze-sensitive proteins through adsorption and precipitation. In practical brewing terms, that means it can help reduce chill haze potential and support colloidal stability when it is used correctly. It also chelates iron, which can help limit oxidation pathways that damage beer flavor over time.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eGallotannin brewing additive for mash tun or kettle use\u003c\/li\u003e\n  \u003cli\u003eHelps reduce haze-forming protein load before fermentation\u003c\/li\u003e\n  \u003cli\u003eSupports flavor stability and shelf-life-focused brewing process control\u003c\/li\u003e\n  \u003cli\u003eCan be used as an iron chelator in the mash or as a kettle fining aid\u003c\/li\u003e\n  \u003cli\u003eUseful for brewers working on bright lagers, shelf-stable packaged beer, and process consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow to use BrewTan B\u003c\/h3\u003e\n\u003cp\u003eDose BrewTan B by weight with an accurate gram scale. Do not measure this product by spoon or volume. Slurry or dissolve it in warm brewing water first, then add it slowly while stirring so it disperses evenly and does not clump. Technical guidance from the manufacturer recommends adding BrewTan B solution to mash water before adding malt when using it at mashing-in.\u003c\/p\u003e\n\n\u003cp\u003eFor kettle use, add the BrewTan B slurry before other kettle finings such as Irish moss or Whirlfloc.

Use extra caution with hazy IPAs, wheat beers, and other intentionally cloudy styles. Standard dosing may reduce haze-active material that those beers rely on for appearance and texture.\u003c\/p\u003e\n\n\u003ch3\u003eProduct details\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct:\u003c\/strong\u003e BrewTan B, formerly Tanal B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e brewing gallotannin \/ tannic acid process aid\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCommon use:\u003c\/strong\u003e mash tun iron chelation, kettle fining, haze and flavor stability support\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eForm:\u003c\/strong\u003e light yellow granular powder\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChemical description:\u003c\/strong\u003e polygalloyl glucoses, hydrolysable tannic acid\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSizes:\u003c\/strong\u003e 1 oz and 1 lb\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eStorage and handling\u003c\/h3\u003e\n\u003cp\u003eKeep BrewTan B sealed, dry, and protected from moisture. Because the dosing range is small, use a scale that can measure accurately in fractions of a gram. Stainless steel equipment is preferred when preparing and using gallotannin solutions because dissolved iron can form dark complexes with tannic acid.\u003c\/p\u003e","brand":"Ajinomoto","offers":[{"title":"1 oz","offer_id":51490380480790,"sku":"additive-brewtan-b-1oz","price":9.99,"currency_code":"USD","in_stock":true},{"title":"1 lb","offer_id":51490380513558,"sku":"additive-brewtan-b-1lb","price":104.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0814\/4807\/5542\/files\/brewtan-b-tanal-b_gnjxzj.png?v=1782972620","url":"https:\/\/socalbrewingsupply.com\/products\/brewtan-b-tanal-b-beer-stabilizer","provider":"SoCal Brewing Supply","version":"1.0","type":"link"}
