Japanese manufacturer Yama makes heat-resistant, glass vacuum brewers that operate on the same principals as the Bodum and Cona models. According to Maria Troy of Sweet Maria’s Coffee, Yama’s U.S. distributors, “with the Yama brewer - if you substitute the Cona glass filter drainer for the cloth filter that comes with the Yama - you have an inexpensive, all-glass stovetop brewer.” Therefore, the Yama’s are elegant and cost-effective and can be easily modified into a machine that would cost much more. The Yama models are available in different sizes and can be used on the stove or on the kitchen table with their optional butane burner!
