As is posted in the Q&A section we answered that question this away:
WHAT ARE THE TEMPERATURE REQUIREMENTS FOR DRY AGING WITH UMAI DRY® TECHNOLOGY?
Dry age at temperature between 34-38F. Typical household refrigerators and restaurant coolers are designed to protect food items like fruits, vegetables, fish and meats from spoilage without freezing them. Please make sure that your refrigerator maintains temperature between 34-38 F to ensure proper aging and prevent spoilage. Ensure that the UMAi Dry® material is in contact with the beef and there are no air pockets inside the bag.
