Van Den Eynde Supercup Black Groundbait 1kg bag Supercup is one of the longest-standing mixes in our range, first developed in the 1980s with the help of Belgian champion Jean Coolens after his double Supercup trophy win. It also played a part in the success of legendary English match angler Bob Nudd, who was crowned Best National Match Angler in 1986. This light brown groundbait has a versatile action, attracting both small and large fish such as roach and bream – making it a reliable choice all year round, in both summer and winter. Supercup can be used in different ways: - On its own, combined with maggots or casters - Mixed 1:1 with leam - As a surface lure to bring fish higher in the water It absorbs a lot of water, swelling considerably during preparation. Typically, 2 kg is moistened in three stages. Supercup can also be made heavier with Secret, Beet or Kastaar when conditions require.
