Canned pumpkin puree is available in grocery stores all year from a variety of producers, including Libby's, Santiam, Pacific Foods and Farmers Market. There are more options during the autumn and winter seasons, including pumpkin puree, which is available at Costco and Trader Joe's stores.
Amazon.com is among the many online retailers that sell pumpkin puree in canned form. As of 2015, there are no commercially available, nationally distributed pumpkin purees available that are not canned or aseptically sealed. Freshly produced pumpkin puree does not have a sufficiently long shelf life to be a commercially viable product. Many companies that produce pumpkin puree, including Libby's, also produce canned pumpkin pie filling, which is a pumpkin puree with spices and other ingredients in the mixture.
