![]() ![]() There are enough viable yeast cells in a sachet of US-05 for direct pitching like this to cause no issues at all. There is no need to stir the yeast into the wort. ![]() This is as simple as opening the sachet and sprinkling the yeast over the surface. There is no recommendation to build a yeast starter so this procedure can be omitted. When it comes to pitching a dry yeast such as Safale US-05 it cannot be simpler.įermentis are quite clear in their instructions that the yeast can either be pitched directly onto the wort or rehydrated first and the resulting slurry pitched. ![]() Pale Ale, IPA, porter, stout, wheat beer, brown ale, amber and beer styles that may promote malt or hop character over yeast character are all suitable for pitching with Safale US-05 Pitching US-05 US-05 is still useful for all kinds of beers, any beer style where the malt and hops need to be accentuated and take centre stage. The Chico yeast is the house strain for Sierra Nevada Brewery and the success of Sierra Nevada Pale Ale meant the yeast found favour in every American style pale ale produced worldwide. Safale US-05 is almost synonymous with American beers of all styles but particularly pale, hoppy beers. Yeast Cell Count: > 69,000,000,000 (69 billion) per 11.5g sachet Safale US-05 Beer Styles Key Figures For Safale US-05įermentation Temperature: ideally 18-28☌ (64-82☏) This is good for active fermentation when you want the yeast roused in the wort but means that clearing the beer will take more time. This means it will take longer for the yeast to settle out if suspension. The flocculation or sedimentation of Safale US-05 is medium. US-05 has a relatively high level of attenuation compared to Safale S-04 for example with upto 82% of the sugars in solution being metabolised by the yeast.Ī higher attenuation results in a drier and less sweet beer. The attenuation refers to the level of sugars fermented into alcohol. This allows malt and yeast to dominate the flavour of the finished beer. ![]() Safale US-05 produces fewer or less flavourful esters than other yeast strains resulting in a more neutral flavour. This results in clean and crisp beers.Įsters are a product of fermentation, chemical compounds that make up a large part of the flavour contributed by the yeast. This particular yeast strain is synonymous with hoppy American style beers which require a crisp finish and allow the hop profile to shine Neutral YeastĪs mentioned before Safale US-05 is touted as a neutral yeast. This results in clean, crisp tasting beers. This can be done with success for lagers, too, by starting the lag phase at 72 to 75° F (22 to 24° C) and lowering the fermentation temperature to 50 to 55° F (10 to 13° C).Safale US-05 is billed as one of the most neutral fermenting yeasts producing low esters. Some brewers begin the lag phase for ales at 72 to 75° F (22 to 24° C), and complete the fermentation at 68° F (20° C). However, the rapidity of growth during this time will affect flavors later in fermentation. Yeast do not create esters until they first make an appreciable amount of alcohols. The yeast produce minimal ethanol at this stage, so ester formation is not a concern. Other than these precursors, yeast produce minimal flavor compounds during the lag phase. This will help the yeast utilize some of these fermentation compounds and will result in a cleaner beer. If you are going to pitch the yeast warm, be prepared to warm the beer back up to the same temperature or higher near the end of fermentation. While it may not create off-flavors directly, it can increase some precursors, like alpha acetolactate, which is the precursor for diacetyl. ![]()
