(BI) - There's no reason to pay $100 — or even $35 — for a bottle of wine.

In fact, unless you're looking out for one specific, pricey bottle of wine, you probably shouldn't be shelling out more than $25.

"There is a value curve that is at its peak between $15 and $25 a bottle," said Devon Broglie, a master sommelier who serves as the wine buyer at Whole Foods. "In that price point is where you get an honest, genuine expression of what a great variety is supposed to taste like, from the region of the world that it comes from, made by an actual person."

Broglie says you can find excellent wines at even lower prices — one of his personal favorites is the $8 Autoritas Pinot Noir.

However, finding the gems under $15 can be hit-or-miss. So, take $15 as a good starting point if you want to figure out what wine made from a certain type of grape or from a certain region of the world is supposed to taste like.

On the other end of the spectrum is wines above $25, Broglie's point of diminishing returns.
