This must rate as one of the most anti-social carp bait smells of the lot, but boy does it attract carp! Notably found in rancid butter and extracted through the process of hydrolysis, this N-Butyric is a totally natural organic acid that comes part and parcel with an acrid taste, a slightly sweet aftertaste - not suggesting you try it - and a sickly smell that practically defies belief. Enhances the year-round attraction qualities of practically any bait. 20ml bottle.
Use either on its own at up to 2ml (48 drops) per 500g mix or at half that level with the flavour or essential oil of your choice. Many top anglers incorporate N-Butyric Acid in virtually every bait they use.
