Maltodextrin Brewing and Taste Test Experiment

The last time I brewed, I decided to do a slight experiment with my new recipe.
Look mom I made beer again
I brewed the same recipe for my new brown ale in consecutive weeks. (I can't resist not buying grain when I'm on that side of town.) The second time I brewed though, I decided to add in 1 oz of maltodextrin to the boil.
A fermenting away we go
I didn't do a new recipe post
Maltodextrin is a white powder that is used to slightly sweeten a (dry) finished beer in addition to improving the mouthfeel of the beverage. It's a tasteless powder that yeast cannot ferment. With the beer recipe I am using now, I'm predicting that it will affect the mouthfeel.

So how much does maltodextrin improve mouthfeel? It was time for a side-by-side taste test.
It's the vanilla extract taste test all over again
Obviously, one of these has had more time to bottle condition
The beer with the maltodextrin added had a slightly different taste than the one without. It felt softer on the mouth and had a smooth aftertaste. But the flavor profile felt different as if it were slightly diluted by the maltodextrin.

The brew without maltodextrin added had a more flavorful brown character in comparison. The aftertaste on this one lingered on the tongue for a bit longer. This one did not taste/feel as smooth as the one with maltodextrin.

So after the taste test, which beer was better? I do enjoy the brown character of this recipe, but after tasting the recipe with maltodextrin, I liked the smoothness too. I think that a balance between the two would be ideal going forward with this recipe. I'd likely tweak the recipe to use only 0.25 oz of Not Cocaine maltodextrin per gallon.

Who doesn't like 2 beers at once?

What did I learn from this? Maltodextrin is useful for creating a "smooth" beer. However, too much can cause bitter flavors imparted from specialty malts to fade away.

Next time I'll try substituting a different specialty malt in place of brown malt.
