#68 Luck O' the Lily Coffee and Cream Milk Stout

Brew date: Feb. 22, 2018

Appearance: Caramel-colored head, nice clean black-brown color.

Aroma: A rich and sweet coffee aroma, some other roastiness. Brownies-in-the-oven, fresh-brewed coffee.

Taste: Good coffee flavor, with hints of chocolate. Not much body for a "milk" stout -- the lactose seems nowhere to be found in the mouth feel. Some astringent flavor at the end, but not off-putting like at tapping. The bitter roast at the end turns slightly sweet from lactose. Finishes fairly dry -- with the roast barley doing its thing.

Final Thoughts: Sort of missed the mark on this one. The flavor is on, but the mouth feel just isn't what it should be. Next time, mash in a few degrees warmer, pump up the lactose, and maybe even add more flaked barley. Also, consider dropping the pH a bit more during the mash to minimize astringency.

Next Time: Consider an English yeast strain or something that adds more character.
