Based on various birdfeeds, milk proteins, high energy sources and water soluble fats, this really is a birdfeed bait with a difference. It has a strong, fruity flavour in the actual base mix giving the bait the ability to overcome what are generally termed 'bottom' smells such as weed and in particular silt. It can be used with any flavours or additives in the Mainline a range, and although aimed at the longer-term use, it will invariably catch from its first introduction due to its unique and remarkable smell. A slightly coarser mix than the Yellow Seed it still remains easy to work with and roll. For anglers that use ground bait for a carp fishing, Essential Opal mixed 50/50 with bread crumb will produce a lovely, fruity mix.
