Ales are brewed with a top-fermenting yeast that thrives at mid-range room temperatures. For this reason, ales are typically stored between 60° and 75° Fahrenheit during the fermentation stage. This type of yeast and the fermentation temperature tend to give ales a fruitier and spicier flavor than lagers. In general, ales are more robust and complex. Common styles of ale include pale ale, India pale ale, amber ale, porters, and stouts.
