The age of wine can be determined by measuring the trace amount of radioactive tritium. Tritium is formed by cosmic bombardment in the upper atmosphere, so naturally occurring water contains a small amount of the isotope. Once the water is in the bottle, the tritium diminishes by a first order radioactive decay with a half-life of 12.5 years. If a bottle of wine was found to have a tritium concentration that is 0.1000 that of freshly bottled wine, what is the age of the wine?
