The DECANTUS uses 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. Wine travels faster through the DECANTUS without a whirlpool effect, because of the vertical planar insert. Reduces free sulphites an average of 56%* (see decantus.net). The froth from DECANTUS has finer bubbles giving smoother aeration
