To pre mix a half gallon (64 oz) add 6 oz of Black Scottie Chai with 58 oz milk (6+58=64 oz).
Tip: Pre-Mark the side of a 64 oz mixing pitcher with a permanent felt pen at 6 oz. Simply fill the pither with Black Scottie Chai up to the 6 oz line and then top off with milk. You can steam the pre-mixed product without hurting the taste.
