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. Due to its strong concentration a 50ml bottle is enough to prepare up to 12kg of boilies. 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.
