Safale S-04 fermentation temp

[CousinAlan]

When s04 and us05 hit peak fermentation your going to ferment 10-15 degrees hotter than ambient temp. When using s04 I keep my beer between 62-65 degrees. 75 degrees is way too hot for any ale yeast. You might get lucky at that high of temp, but if you want to make consistently good tasting beer you must have control over fermentation temperature! Relying on ambient temp and hoping for the best is foolish.
