Our commitment to quality Quinzi's have always strived to produce the highest quality products. This is reflected not only in the way we prepare our ingredients, but also in our practice of hand sorting, plus the packing of our sweets in high-density bags to protect them from moisture. Our commitment to quality has recently been recognised with Quinzi's Confectionery achieving HACCP quality endorsement. All this plus a 2-year shelf life which Quinzi's is prepared to back with a Guarantee. Hazard Analysis and Critical Control Point (HACCP) is an internationally recognised system for managing the risks associated with food and beverage safety. Designed to provide increased control during critical stages during food preparation, HACCP is a systematic method using the "Seven Principal System" for analysing and controlling food processes.
