Tried brewing a session stout that came out way too sweet for my taste. It has been kegged for a month and is still really sweet so I am thinking about boilling 2 quarts of starter wort with some additional hops to add to the beer in the keg. Anyone have an idea if this will help bring some balance to the taste of the beer? It is a 2.5 gallon test batch and I am using 1/2 oz of fuggle hops boilled for 50 minutes.
