A low-alcohol IPA designed for drinkability without sacrificing the hop-forward character that defines the style — typically 4.0–5.0% ABV with IPA-level bitterness and aroma relative to the reduced malt base. Pale gold to light amber, with bold American hop aroma and flavor carried by a light, crisp body. A defining category of the 2010s craft expansion.
In the glass
Origin
The session IPA grew out of a broader push for low-alcohol, full-flavored craft beer. Beginning in 2009, the writer Lew Bryson campaigned through his Session Beer Project for beers of about 4.5% ABV — flavorful enough to be interesting, modest enough to drink several in a sitting. The commercial breakthrough came from Founders Brewing of Grand Rapids, Michigan: brewmaster Jeremy Kosmicki developed All Day IPA to deliver IPA-level hop character at low strength, releasing it seasonally in 2010 and year-round in 2012 at 4.7% ABV. All Day IPA’s success demonstrated the format could work at scale, and other major craft breweries quickly followed with session-strength IPAs of their own.
Notes
The style overlaps with American pale ale and the older English tradition of session-strength ales. What sets a session IPA apart from a low-gravity pale ale is the hop-to-malt ratio — session IPAs push hop aroma and bitterness much higher than a pale ale at the same gravity. The category’s central challenge is delivering that big hop impression without the malt body to support it; the best examples taste structurally sound rather than thin or harsh.
