From a crowler into a thermal mug where I couldn’t see it all that well. Tart, citrusy hops and a light body. It’s a little punchy, not a chugging beer. Great sipping IPA.

From the crowler, it pours a hazy light amber color with a nice white head that slowly reduces and leaves lacing. The nose gets a citrus scent, very fresh seeming. The mouth gets a citrusy tartness, which you feel in your cheeks, followed by a pleasant citrusy maltiness. They call it a flagship beer and I agree.

Pours a hazy golden with soapy white head. Mango and pineapple on the nose. I think often with mosaic forward IPAs, you get a lot of dole pineapple. You know, in that pure sweetness kind of way. This has more of a fresh pineapple character so with much of that sweet tropical character with a touch of tang to placate the palate. There's also a touch of barky dryness on the finish which gives this IPA more depth. This is a delicious and well done IPA.

L: Had this on-tap at Final Gravity's taproom, poured into a snifter glass. Had a bright, golden yellow color and a pretty cloudy consistency. There was a half inch of foamy, somewhat long-lasting head. Average lacing.
S: A very nice aroma of citrus fruit, tropical fruit, malt, and hops.
T: Tasted of a small amount of malt (mostly in the finish; very faint), a good shot of tropical fruit (mango and passionfruit), a moderate amount of hops (not overdone, though), and some citrus fruit as well (orange and lemon). A decently sweet, only slightly bitter flavor. It's incredibly well-balanced and flavorful. Pretty tasty.
F: A good amount of carbonation with a smooth finish. Medium-bodied.
O: An extremely well-made IPA. Drinkable.
