On Isla Teja at Km5 on the road to Niebla, you'll find the south's best large-scale brewery. Tours leave hourly from noon to 11pm (CH$10,000; November to March) and include a takeaway glass mug and a 300ml sampling of the Torobayo unfiltered, available only here, straight from the tank.
Unless you're a beer-history nut, the cost of the tour is better spent on sampling your way through the 10 or so beers on offer here, chased with hearty German fare that includes lots of pork chops, späetzle, sauerkraut and apple sauce. There isn't a German in sight, and it's nearly overflowing with tourists and tour buses, but you could do worse than drinking away an afternoon here. Bus 20 from Carampangue to Isla Teja (CH$550) can drop you off – a good idea even if you have wheels.
