  • Molasses additions

    Hi all,

    About to brew a sweet potato Porter, and would like to add molasses to give it a little more character and get the OG up as I have a severely undersized MLT. I haven't been able to find much info regarding which type of molasses and a good but safe % to add. I've never used any type before but I think I've narrowed it down to the sweet/medium/bakers grade, but know I'm looking for amount per bbl. Brewing on a 7 bbl system. Any recommendations or experiences greatly appreciated!

    I've used it in Porters, Amber ale, and even in an APA. For porter, I used about 7.5# per bbl and wished I had bumped it up to 10#/bbl, Amber used about 5#/bbl and liked the rum-like subtle character, APA was about 1#/bbl and added a slight mineral character and dryness with a little bit of vanilla. I have also used dark brown sugar in Porter and Saison in about the same rates as above.

      Thanks for the reply Todd,

      Which grades have you used? I've heard of mineraly/metallic issues when using blackstrap.

        Some years ago when brewing in a brew pub, I used 6 gallons of blackstrap in a 10bbl batch of brown ale (grains were 400# pale ale malt, 20# chocolate). It had a notable molasses/irony flavor, but very pleasant... you could compare it to the effect you get from a good Irish dry stout. It was a very popular beer in the pub and I am considering making it again at my current brewery.
