Flat Brain Red IPA. A rich malt body delivers caramel and toffee flavors while bright Citra hops bring the flavors if nango, grapefuit and lychee. Smooth and complex with a crisp finish.

Pours a crystal clear ruby hued copper color with a foamy tan head that lingers and provides splotches of lacing. Beautiful red IPA.

The nose features mango, ripe grapefruit, and some floral hop aromas, and there’s a nice bit of caramalt as well. Very nice.

The taste is a nice blend of the mango, grapefruit, and floral hops in balance with the caramalt. This is really delicious.

The mouthfeel is medium and very crisp, on point for this exceptionally well executed Red IPA.

Pours a dark red color with a minimal head that lasts quite a while. Aroma of roasted malts with notes of bread. Taste is slightly spicy and a bit on the bitter side.
