Degree hour

The industry term for this is “time temperature exposure”, which we express in degree hours. One degree hour equates to 1 hour x 1°C. For every 500 degree hours, one day of vase life is lost. At an average room temperature of 20°C, this means that one day of vase life is lost in approximately 24 hours.

The industry benchmark states that no more than 1 day of vase life need be lost in the supply chain, from harvest to shop floor.

A short throughput time and the lowest possible storage temperature in the chain are a guarantee of long vase life. Therefore, it is important for the industry to keep the vase life lost to a minimum. This requires the chain to be monitored, so that processes and transport and storage methods can be adjusted where necessary.
