The Thortruffles are shipped in breathable bags and slowly lose water during transport. This way, they retain their active ingredients and can be kept for a very long time (more than a year) at room temperature and normal humidity.
Please note: As the truffles travel and water evaporates, they lose up to 70% of their weight. This makes them no less, but actually more suitable for microdosing. Dry truffles release their active substances slower, which avoids the “head rush” sometimes experienced with fresh truffles.
