Keystone Pretzel Bakery is known for its delicious variety of pretzel products, but it is important to note that, as of my last knowledge update, they do not specifically advertise gluten-free pretzels. The bakery specializes in traditional pretzels made with wheat flour, which means they are not suitable for those with gluten sensitivities or celiac disease. However, many customers enjoy the diverse selection of products offered, which may include other snacks or baked goods that could meet different dietary needs. For the latest information regarding the product line, including any potential updates or new offerings, it may be beneficial to visit the official website or check their current product listings. This will provide the most accurate and up-to-date details regarding dietary options available at Keystone Pretzel Bakery.
