5. Wine Cellar
One of the benefits of immense wealth is being able to afford luxury products like fine wines. Wine is an expensive commodity because some bottles are very rare. The vintage also affects the cost because some years are better than others (via Decanter).
Mahomes and Brittney have their own wine cellar in their home. It’s a classy space with room for dozens of bottles. They have enough room for their favorites as well as exclusive bottles for special occasions. This is a lavish luxury but a fantastic one for Mahomes and his wife.
