I just retrieved four pounds of aged Nightcap which has been stored carefully for the past four years. I bought it while it was still available in bulk. The aroma from the sealed outer container is unbelievably wonderful. I have never cellared pipe tobacco before. Should I break it down into smaller jars for immediate use and continued ageing? I there any advantage to opening well-sealed bulk containers if the first seems fine, or should I let well enough alone?
