Sensory Description:

A pillowy haze veils this IPA, offering a soft golden hue with a glowing, opaque body. The aroma is explosive with notes of ripe mango, fresh-squeezed orange juice, and hints of passionfruit, suggesting a generous late-stage dry-hop. On the palate, Flatiron Fog is lush and mouth-coating, with soft carbonation and no harsh bitterness. The use of oats and wheat provides a silky texture, while the yeast contributes tropical esters and light stone fruit notes. Despite its juicy character, a subtle dankness lingers in the background, offering complexity and balance.
