In Rheinfelden you'll find the Feldschlösschen brewery, 18km east of Basel and housed in a 19th-century building with a name that means "little castle in the field" – an accurate tag. Two-hour tours (in German) with beer tastings can be arranged. The brewery is a 10-minute walk from Rheinfelden train station.
Call ahead to see if you can tag along with an existing group (per person Sfr20).
