Our family have been tang consumers for years. we take 2 qts. of orange juice and combine with 2 qts. of orange tang in gallon jug. tastes great the addition of vitamins added to the mix. we buy the12.3 oz. container that makes 8 qts. the new tang is 1 lb.4ozs. makes 6 qts. only contains calcium, vitamin c. what's the deal. what changed and why?ingredients seem to be listed the same calcium went up more ground up rocks for filler? more sugar, was there artificial sugar in it before and was not listed?in a world of products that have been shrinking in size only to cost same. I just have to ask what's going on. not sure if we are going to purchase any more.....
