This is the same additives as the WINTER FEEDING ADDITIVES.  

We recommend adding these additives to your fall and spring 1:1 sugar water and to your winter-bee-kind refills. These additives contain everything needed. DO NOT ADD any additional items to your sugar water once you've added these additives.  Add 1 tsp of each vial to 1:1 sugar water and the same for 1 winter-bee-kind refill. 

There is enough to make 5 quarts of 1:1 sugar water and to refill  5 Winter-Bee-Kinds.
