Mulling spices are gathered together in the Floating Basket and placed directly into any beverage (tea, coffee,wine etc.). You may use any spice i.e. nutmeg, cloves, cinnamon etc. Its tall hat makes it easy to remove the filter out of any hot beverage. The filter and the hat do not separate during this process. Once the brew is complete, the hat can simply be flipped over and used as a drip-off tray for the used  filter.
