Robust Porter

Robust Porters are very dark to black. Hop aroma is very low to medium. They have a roast malt flavor, often reminiscent of cocoa, but no roast barley flavor. Caramel and other malty sweetness is in harmony with a sharp bitterness of black malt without a highly burnt/charcoal flavor. Hop flavor is very low to medium. Hop bitterness is medium to high. Diacetyl is acceptable at very low levels. Fruity esters should be evident, balanced with all other characters. Body is medium to full.
