Sensory profile

Appearance

Aroma

Coffee, cocoa, toast and dark grain; esters and hops vary by substyle.

Flavour

Roasted malt from dry and bitter to sweet and chocolate-like.

Mouthfeel

Medium-light to full; nitrogen service may create a creamy texture.

Pale malt with roasted barley or dark malts, ale yeast and balancing hops.

History

Stout evolved from stronger porter in Britain. Irish dry stout, sweet stout, oatmeal stout and imperial stout later became distinct traditions.

How it is brewed

Roasted grain quantity and mash treatment control acridity. Water alkalinity can buffer acidic dark malts, while chloride and sulphate influence fullness and bitterness.
