Premium Flavours are extraordinarily concentrated thus a very small amount like 4ml is enough to add to a 1kg boilie mix. Among the flavours, Premium represents the highest quality. We recommend using these oil-based products on waters where the temperature is above 8 oC. Premium flavours render boilie making very cost effective while using the best quality flavours. All SBS flavours are cook proof, meaning that following a 2 minute boiling period the boilies retain most of the flavour and fragrance matter.
