At nearly 40 million, the Corolla IS the best-selling nameplate - just not the biggest selling single design. And Asahi - a girl's blouse Japanese beer - from an Adelaidean, home of Australia's greatest beer (Coopers of course!)
Oettinger is the best selling beer in Germany (passing Krombacher in sales in 2005) because it's designed to be brewed cheaply. Oettinger only sells bottled beer, thus avoiding the 0.25 Euro can deposit fee in Germany. It's hardly ever available on tap in pubs and clubs, and is sold mostly in bottles by the crate in supermarkets and liquor shops in Germany. Oettinger doesn't advertise; there is only one 'Oettinger' brand, albeit in different styles, and there are no third-party wholesalers involved. Oettinger trucks deliver directly to stores.
Production is highly automated, although by law it still has to be made using the German Reinheitsgebot law - barley, hops, yeast and water only (Australian beers can have sugar, preservatives, additives, colours, and all sorts of crap added). However Oettinger is not regarded as high in quality as the more famous German beers. Oettinger boss Gunther Kollmar was quoted as saying (in the Der Spigel magazine, translated) :
"The term cheap beer is actually almost a disqualification. But it's only an attempt. Everything that is marketed well and market adjusted in Germany, is suddenly (called) cheap. Aldi is cheap, IKEA is cheap, the Bild Newspaper is cheap, Oettinger Beer is cheap. Nobody wants it. Yes, it's a gnat's piss! But everybody drinks it. (Our) success proves us right."
