Today's Pascua Pit Stop heads to a place where many West Michiganders go when heading out on a road trip -- Traverse City!

Mari Vineyards is the first northern Michigan winery with an extensive underground barrel aging area. When you pull up, you'll see the outside of the caverns that are at a depth of at least 10 feet below ground.

Temperatures are consistently between 55 and 60°F and a humidity over 70 percent, both of which are considered ideal for winemaking.

Meanwhile, the wine caves, which reside beneath the winery between 12-27 feet below ground level, are aligned with the summer solstice so that the sun rises in the center of the "summer solstice" passage.

Owner, Marty Lagina purposely designed the wine caves to bring in the light of the summer solstice.

The oculus, which is the center of the wine caves, boasts a circular opening at the center of its domed ceiling. The design allows light to shine down from above ground. At the focal point is a large compass rose which points at the suns position during the solstice.
