The term 'Strong Porter' is a type of beer that is dark and robust in flavor. It is a combination of a porter and a STOUT, which are both dark beers. The term 'STOUT' is often used to describe a strong porter, as it has a higher alcohol content than a regular porter. Strong porters are usually brewed with roasted malts, giving them a deep, rich flavor. They are also known for their smoothness and full body.
