From the brewery:

Sonoma encapsulates what we love at Track. A refreshing, sessionable, hazy pale ale to be shared, which shows our love for hops & the pursuit of pale perfection. With a simple malt base & hopped generously with Mosaic, Centennial & Citra it bursts forth with resinous notes of sticky mandarin and grapefruit. It finishes crisp & clean with a soft, pithy bitterness.
