Would it surprise you to learn that scientists at the University of Idaho have done extensive research on proper potato storage? We're talking a shelf life of up to three months in a properly outfitted pantry:
Above: A Pine Wood Potato Rack extends shelf life by allowing air circulation; it's 94€ from Manufactum.
Why is air circulation important? "Since potatoes are living organisms, they 'respire' or produce carbon dioxide, so allow some air circulation around your potatoes," researchers in Idaho recommend. And they should know; Idaho is the nation's top potato-producing state, with 14.3 billion pounds grown in 2012.
Above: The German-built potato rack will hold up to 110 pounds of potatoes. It is made of untreated pine; assembly is required.
Store potatoes in a cool dark pantry—preferable at a temperature of 45 degrees. At warmer temperatures, they will sprout sooner.
