It produces a dry, crisp finish that lets hop character speak for itself, with very low ester production and minimal diacetyl.\u003c\/p\u003e \u003cp\u003e\u003cb\u003eBest Suited To\u003c\/b\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eAmerican Pale Ale, West Coast IPA, American IPA\u003c\/li\u003e \u003cli\u003eAmerican Amber, American Wheat, Cream Ale, Blonde Ale\u003c\/li\u003e \u003cli\u003eAny ale style where a clean, neutral fermentation profile is the goal\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 15–24°C (optimal 18–22°C)\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eAttenuation:\u003c\/strong\u003e 73–77%\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eFlocculation:\u003c\/strong\u003e Medium\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eAlcohol tolerance:\u003c\/strong\u003e Up to 11% ABV\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003ePitching rate:\u003c\/strong\u003e 50–80g per 100L (1 sachet per 23L)\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cb\u003eWhen to Choose US-05\u003c\/b\u003e\u003c\/p\u003e \u003cp\u003eChoose US-05 over S-04 when you want a drier, cleaner finish and your recipe is American rather than English in character. S-04 leaves more body and clears faster; US-05 ferments more completely and is more neutral.\u003c\/p\u003e \u003cp\u003eChoose US-05 over M44 when you want a more forgiving, faster-starting fermentation. M44 attenuates higher and flocculates better, but has a 24–48 hour lag phase that catches beginners off guard. US-05 gets going quickly and is more reliable for first-time brewers.\u003c\/p\u003e \u003cp\u003e\u003cb\u003ePractical Notes\u003c\/b\u003e\u003c\/p\u003e \u003cp\u003ePitch directly onto wort at fermentation temperature, or rehydrate in 10x its weight in 27°C water for 15 minutes. Direct pitching is fine at standard gravity.\u003c\/p\u003e \u003cp\u003eRehydration matters above 1.060. If your original gravity is pushing past that, rehydrate first — it improves cell viability and reduces fermentation stress at higher gravities.\u003c\/p\u003e \u003cp\u003eFerment at 18–22°C for the cleanest result. Above 23°C you will start picking up light fruity notes that detract from the neutral profile.\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":"Fermentis","offers":[{"title":"Default Title","offer_id":41994500472909,"sku":"25016","price":9.5,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0635\/8306\/0045\/files\/saf-ale-yeast-us-05-11g.jpg?v=1785301964","url":"https:\/\/www.australianhomebrewing.com.au\/products\/saf-ale-yeast-us-05-11g","provider":"Australian Home Brewing","version":"1.0","type":"link"}
