Spaten is by far the least-known of the big six, and as a company is actually merged with Löwenbräu, though you’d never know it. Spaten’s claim to fame is that the company essentially invented Oktoberfestbier, the Märzen beer for the 1872 event. It was also the first brewery to make Pils beer in Munich and produces the Franziskaner Weissbier, often available abroad.
