A unique by-the-glass wine decanting system, the DECANTUS utilises the Bernoulli (a Swiss scientist) effect where the reduced pressure of a stream of fluid (wine) draws an air flow through diagonal thin tubes inside the DECANTUS. The wider opening on top and larger liquid capacity of the top reservoir bowl makes pouring into DECANTUS much easier than other aerators. Wine travels faster through the DECANTUS without a whirlpool effect, because of the vertical planar insert. The "froth" from DECANTUS has finer bubbles giving smoother aeration than any other aerator on the market. Includes base, pouch, and cleaning brush! A stainless steel strainer is also available to purchase separately if desired.
