Jay Curry holds a huge mirror from a very difficult venue. Liquid flavours used at the correct levels within a good quality food bait can make a big difference.
Liquid flavours play an important roll within the creation of a successful long term bait recipe for a number of reasons. They will not only help to give the finished bait it’s own unique taste profile, but also give it a distinctive ‘label’ that the carp will come to recognise through association. In other words, you will be educating them to eat the bait and recognise the 'taste' and 'smell' over a period of time.
Be careful not to get flavours confused with attractors though, because in terms of nutritional value, unlike liquid foods, they have little or no food value, however, for the reasons outlined above, they are a very important addition to any successful recipe.
