After landing Runway XX in ZZZ1; the flight attendants reported a 'smell' in the cabin. I continued taxing to the gate. Thinking the smell was from a normal source; engine exhaust; brakes; tires...  The APU bleed was opened to discount the engine bleed. The taxi in was of minimum time. After shut down was complete; I contacted the cabin the smell was then described as a 'dirty sock'. I had the flight attendant open an aft door; after verifying it was disarmed; and a cockpit window was opened to increase air flow through the cabin. The light passenger load was deplaned in minimum time. Maintenance was contacted and Smoke; Odor and Fumes Report was compiled with and sent to maintenance control via duty pilot due to IT issues.Short taxies to a gate are a high threat phase. I was focused on getting the plane to the gate safely. [Reporter suggested] accurate communication between cabin and cockpit crewmembers [during fume events].
A321 Captain reported a fumes event during taxi-in. Aircraft was turned over to Maintenance for inspection.
