Hydrosols

Controlled-Temperature Storage at the End

One the hydrosols arrive, get them to a cool storage as fast as possible. I have found that a constant-temperature environment that fluctuates no more than two or three degrees Celsius in either direction is as important as the baseline temperature. Ideally, hydrosols should be stored in an area that is kept around ten to thirteen degrees Celsius. 

This is slightly warmer than most refrigerators, but refrigeration certainly does them no harm and is the easiest method of temperature control for smaller quantities. A cold room is the perfect option for large amounts, and if you are considering handling hundreds of litres per year, this option is worth investigating. Cold rooms protect your investment and protect your customers.
