Safale US-04 from Fermentis is the best yeast for a wide variety of English ales. You can re-hydrate but it works very well simply sprinkled over the surface of the wort for a few minutes to reconstitute with plenty 02 and then stirred in. Very dependable dry yeast that you can use for practically any English-style beer. One packet is sufficient for 5-6 gallons. Dependable, difficult to screw up but does ferment aggressively. You’ll see what I mean!
Safale S-04 forms a very compact sediment at the end of the fermentation, helping to improve beer clarity and increase yields. This yeast is the BEAST, a VERY strong fermenter – Make sure you have plenty of head space in your fermenter and that your blowoff tube is ready!
