The Rutledge Rita’s will not be under supervision this year. They will carry some non-kosher products.
Not all flavors are supervised by the OK. Please check each type for supervision. Mixed cases are sold, some bearing an OK and some do not. The non-supervised bottles may contain grape-juice.
It is very common for supermarkets to change the suppliers for their store brands. Being that some of the suppliers have kosher supervision and some do not, a product which you have been using may suddenly appear with the same label sans supervision. Sometimes old and new stock appear together on a shelf mixing supervised product with non-supervised product.
