Timmermans Flute beer glass. The world's oldest current operating lambic brewery, Timmermans, mainly produces sweet and cider-like fruit lambices. In recent times, however, they have begun to return to the more traditional lambics. This type of glass is designed for fruit lambices and rests on a stable stem. The body itself is slightly cup-shaped. The carpenter's logo is printed on the front of the glass. On the back there are 2 coronation lines, at 25 and 33 cl.
