The secret sauce behind a 147-year-old brew

Amsterdam's old Heineken brewery has been turning out its signature beer since 1864 when Gerard Adriaan Heineken founded Heineken & Co. Thus began a proud family tradition of brewing premium-quality beer that's proved extraordinarily popular with customers around the world.
