Storage and handling factors can greatly impact the quality of our milk products. If stored under proper conditions (between 33 and 40°F), we guarantee its freshness up to the sell-by date if unopened. Our pasteurized milk products are best when consumed within 5-7 days and our ultra-pasteurized products are freshest-tasting within 7 days of opening. It is easy (though not always pleasant) to identify spoilage in a dairy product. If it looks, smells, and tastes OK, it is probably OK to consume, within the above timeframes.
