Ask the vendors you purchased from. That's what I did. Some say yes absolutely for their liquids, others say does keep cool & dark. In my house I don't really have anywhere that is consistently under 60 degrees. I have some in the fridge and some in the coolest part of my house. One vendor did suggest a wine refrigerator. That would be neat! Apparently refrigeration can cause some of the flavor in the juices to separate or degrade. Some are apparently perishable. Just email your vendors and go with what they suggest. All my juices are mixed when I order them so I tend to trust what they are telling me. Hope this helps.
