It is a very low-flocculating yeast by design: hefeweizen is meant to be hazy, and the yeast in suspension carries the flavour.\u003c\/p\u003e \u003cp\u003e\u003cb\u003eBest Suited To\u003c\/b\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eBavarian Hefeweizen, Dunkelweizen, Weizenbock\u003c\/li\u003e \u003cli\u003eAmerican Wheat Beer where banana and clove character are wanted\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 18–30°C (temperature controls banana\/clove ratio)\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eAttenuation:\u003c\/strong\u003e 68–72%\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 M20\u003c\/b\u003e\u003c\/p\u003e \u003cp\u003eChoose M20 over M21 Belgian Wit when you are brewing hefeweizen rather than witbier. M20 leads with banana and clove; M21 is more citrus-forward and spicy. For authentic German wheat beer character, M20 is the correct strain.\u003c\/p\u003e \u003cp\u003e\u003cb\u003ePractical Notes\u003c\/b\u003e\u003c\/p\u003e \u003cp\u003eThe banana\/clove ratio is temperature-controlled. Ferment at 18–19°C for more clove character. Ferment at 22–25°C for more banana. A balanced result is typically achieved around 20°C. Decide which direction suits your recipe before you pitch.\u003c\/p\u003e \u003cp\u003eDo not cold crash or fine a hefeweizen made with M20. The yeast in suspension carries the flavour — a clear hefeweizen has lost its character. The haze is not a defect.\u003c\/p\u003e \u003cp\u003eDo not over-pitch. A slightly lower pitch rate than usual produces more ester expression in wheat styles.\u003c\/p\u003e \u003cp\u003eKeep refrigerated. Once opened, reseal and use within 7 days.\u003c\/p\u003e \u003cp\u003e\u003cem\u003eReviewed by the AHB Brewing Team — June 2026.\u003c\/em\u003e\u003c\/p\u003e","brand":"Mangrove Jack's","offers":[{"title":"Default Title","offer_id":41994559324237,"sku":"25005","price":9.5,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0635\/8306\/0045\/files\/25005.jpg?v=1754053055","url":"https:\/\/www.australianhomebrewing.com.au\/products\/mangrove-jacks-beer-yeast-bavarian-wheat-m20","provider":"Australian Home Brewing","version":"1.0","type":"link"}
