This has to be considered one of the most socially carp-baiting smells of the lot, but boy does it attract carp!
Particularly present in rancid butter and extracted through the process of hydrolysis, this N-butyric acid is an entirely natural organic acid that combines a pungent flavor, a slightly sweet aftertaste—not that we suggest you try it—and an unpleasant odor that practically defies belief.
Use alone up to 2ml per 500g of blend or half that level with your favourite flavour or essential oil.
Many top anglers incorporate N-Butyric Acid into virtually every bait they use and, when paired with the flavour of Nature Identical Pineapple, it must surely be considered one of the greatest carp attractors ever.
