I will soon be moving to another region of the country, and I have always wanted to make a time capsule. Why not combine the two? My grandparents live about an hour away and have a house that is partially/mostly underground. I plan on making a concrete sealed time capsule and putting a few items inside for 25-30 years.
My question is two fold: First, any recipe suggestions for a show mead that will really benefit for this long type of aging? Something really nice. Second, what kind of container and closure would be best? I was thinking a wine bottle with a synthetic cork sealed in heavy wax. I want to store away two bottles, one just a still mead and the other exactly the same but with a single oak cube from some nice oak trees on the property.
