I have a house porter that I love but was thinking of adding some Munich malt? Anyone have an opinion on if and how much? This is the malt bill that I’m pretty happy with as it is. Just like to experiment.
11lb. 2row pale
1lb crystal 40
1lb Chocolate malt
8oz flaked barley
4oz black patent malt
1oz roasted barley
I can’t really comment on the Munich addition, other than to say: it’s your beer, make the way you like. Regarding the grain bill, I’m a bit of a traditionalist and porters happen to be one of my favorite styles. I have found the additions Brown Malt to the grain bill really adds that nice roasted flavor in a porter. I typically add about 8 oz. in a Brown Porter and a bit more in a Robust Porter. Works really well IMO.
I personally like Munich Malt and I substitute it for lower crystal malt regularly. It all depends on what you are seeking. Sub it in your recipe at say a pounder so with a pound or so less of the 2 row or just add it in at the amount you feel comfortable with - it’s your batch and I am sure you will find it drinkable, if not terribly different.
If I use regular pale malt as the base I normally add some munich but I prefer using maris otter as a base in which case I leave it out. For my tastes pale + munich is a close approximation of maris otter and adding munich to maris otter puts the beer a little out of balance.
However, if you’re happy with your current recipe then why change it?
I throw 2 lbs (18.6%) into my porter and it gives it a little extra something I think. My recipe isn’t wildly different from yours either, so I think it would work quite nicely.
