Low FODMAP
Yes — Beer is low FODMAP in normal servings and is generally well tolerated by people with IBS.
Low-FODMAP serving
1 can/bottle (375-425 ml)
Becomes high FODMAP at
multiple beers (cumulative + carbonation)
A standard serving of regular beer is low-FODMAP despite being grain-based, as fermentation removes most fructans; limit to one as alcohol and carbonation are gut irritants.
Seen a different rating somewhere else?+
Usually it's a portion difference, not a disagreement. This page scores beer at a serving of 1 can/bottle (375-425 ml); at multiple beers (cumulative + carbonation) it belongs in the high band. A source quoting the larger serve will call it high, and one quoting the smaller will call it low — the same food, measured at two different amounts.
