The ISAR is our best-known beer mug shape, most notably due to the global popularity of Oktoberfests. Oktoberfest organisers, however, opt for our glass not only because of its shape, but also because of its weight. Using IS technology, it is possible to make the glass about 50 % lighter than by using press technology. This mug is also known as the “Augenkanne” in many places. Its flat, round dimples give the body greater stability and a more appealing appearance. ISAR beer mugs are available in four sizes from the 4 cl spirits glass to the 1 l tankard.
