For unopened roasted beans, check the stated date, intact seal and supplier storage instructions. The pack design and documented product specification matter more than an unsupported promise that beans will remain fresh for years.
After opening, protect beans from air, moisture, heat and light. The
National Coffee Association’s storage guide explains these freshness factors. Keep the container closed and choose a quantity that suits how quickly you brew.
A roast date or valve helps describe the product and pack; it does not replace the stated shelf life or prove that a damaged bag has been stored correctly.
