Great pretzel flavor, great pretzel crunch. Continuing the family tradition. In 1964 Mark Dieffenbach started making potato chips on his kitchen stove in Berks County Pennsylvania. A short time later he built his own kettle cookers, which the third generation of the Dieffenbach family is still using today, to bring you the best potato chips and pretzels from the finest hand selected ingredients. We are sure you will find our potato chips and pretzels to be the best you've ever tasted.
