In the past few years, a surplus of grapes led to low prices for good quality wines. But industry experts are predicting the prices will increase by the summer and a shortage of grapes in California could last for several years.

In Indiana, an extremely warm March caused grape vines to sprout prematurely, making them vulnerable to April frosts.

Oliver Winery in Monroe County frantically fought Mother Nature, RTV6's Tanya Spencer reported.

Vineyard workers used frost fans and hired a helicopter to push warm air down to the ground.

If not for those efforts, Oliver Winery may have lost its entire crop. Instead, it estimates it only lost about 20 to 30 percent.

Some Hoosiers said they’d be willing to spend the extra cash if wine prices increase this summer.

"I usually don't buy wine often, but when I do, I'm willing to spend the extra money on it," wine drinker Taylor Moreau said.

"I actually might pay more to get my favorite,” said another wine lover.

The Indiana Wine Grape Council said it could be the end of May before it would be able to project how much prices would increase and that cabernet and zinfandel will likely increase the most.
