I am currently making a batch of wine and have always just drank it after i make it. Soon i will be getting married and was thinking I will take a bottle and save it for 20 years for our anniversary. I wanted to know if it was a good idea to place my bottle in a pvc pipe capped on both sides and burry it 4 feet in the ground underneath of a boulder with a marker under it of some sort. Any cons to this idea that anyone might have would be much appreciated because i can't see any.. Dark 50-55 all year round.. unmoving. lemme know what you all think.
