The unique three-phase aeration and oxygenation system provide up to twice as much aroma and flavour compared to serving from a bottle or traditional decanter. The included stainless steel filter removes sediment and the mouth-blown double-walled glass globe and twister guide the wine into the crystal clear decanter using a highly efficient process of oxygenation. Set includes a double-walled glass aerator, a 750ml blown glass decanter and a stainless steel sediment filter.
