{"product_id":"mangrove-jacks-beer-yeast-belgian-wit-m21","title":"Mangrove Jacks M21 Belgian Wit Yeast 10g","description":"\u003cp\u003eM21 produces the citrusy, spicy, softly hazy character of Belgian witbier. It pairs naturally with the traditional wit additions of coriander and dried orange peel, complementing rather than competing with them. Very low flocculation is a characteristic of the strain — the beer is meant to stay hazy.\u003c\/p\u003e \u003cp\u003e\u003cb\u003eBest Suited To\u003c\/b\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eBelgian Witbier (Bière Blanche)\u003c\/li\u003e \u003cli\u003eAmerican Wheat Beer with character\u003c\/li\u003e \u003cli\u003eLight Belgian ales\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cb\u003eSpecs\u003c\/b\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003e \u003cstrong\u003eFermentation temp:\u003c\/strong\u003e 17–23°C\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eAttenuation:\u003c\/strong\u003e 70–75%\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eFlocculation:\u003c\/strong\u003e Very Low (permanent haze — expected)\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eAlcohol tolerance:\u003c\/strong\u003e Up to 12% ABV\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003ePitching rate:\u003c\/strong\u003e 1 sachet per 23L at standard gravity\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cb\u003eWhen to Choose M21\u003c\/b\u003e\u003c\/p\u003e \u003cp\u003eChoose M21 over M20 Bavarian Wheat when your recipe is witbier rather than hefeweizen. M20 leads with banana and clove; M21 is more citrus-forward and spicy. The styles are related but the yeast character is distinct — use the correct yeast for the style.\u003c\/p\u003e \u003cp\u003e\u003cb\u003ePractical Notes\u003c\/b\u003e\u003c\/p\u003e \u003cp\u003eDo not fine or filter a witbier made with M21. The permanent haze is the yeast in suspension — it carries the citrus and spice flavour. Fining removes the character you brewed for.\u003c\/p\u003e \u003cp\u003eSwirl the bottle before pouring to resuspend the yeast sediment — this is the traditional way to serve witbier.\u003c\/p\u003e \u003cp\u003eFerment at 18–20°C for a balanced citrus-spice profile. Warmer fermentation pushes more ester expression.\u003c\/p\u003e \u003cp\u003eKeep refrigerated.
