I found this under the FAQ section of the Smucker's site:
Q. Do I have to refrigerate Smucker's peanut butter?
A. The food items we produce are classified as non-perishable. Refrigeration is not necessary, although it does slow down the oil-separation process.
Q. Should I refrigerate your preserves, jellies, toppings, etc.?
A. The food items we produce are classified as non-perishable. Refrigeration is not necessary but recommended. Under normal conditions, unopened products should remain safe to eat indefinitely. However, over time the flavor and color of products will decline. Our products have a "best when purchased by" date on the back label.
Here is information about storing butter:
"We recommend that butter be refrigerated at 32º - 38ºF. Bring out only enough butter that you plan to use for each meal. After use, any remaining butter should be returned to the refrigerator immediately, making sure it is covered or re-wrapped, to insure freshness and flavor. Butter is very susceptible to picking up foreign odors and flavors and should always be stored away from highly aromatic food products. Heat and light speed undesirable chemical and physical changes in butter. If it is not refrigerated, or left out for prolonged periods, this could cause flavor changes, rancidity and mold growth."
"Store butter in the refrigerator for best quality. Butter should be stored in its original carton or a covered container. The butter keeper in the door of the refrigerator is NOT the best place to keep the butter as it is sometimes warmer than the rest of the refrigerator"
