Wine is one of Virginia's biggest industries.
As summer is ending, it's an important time of year for Winemakers in the Valley, it's now time to harvest those grapes.
Before they harvest the grapes are tested for sugar and pH levels, or their testing the acidity.
Lee Hartman is the winemaker at Bluestone Vineyards in Bridgewater.
He says they're still trying to see how much damage the late frost in May has affected their crop this year.
Hartman says, "It's going to be hard to tell until we bring in our harvest this year, but I'd say in some varietals at least half."
Hartman says some grapes bounce back easier than others.
The late frost and cooler weather has done more than just put the grapes in jeopardy, it delayed their harvest quite a bit.
Summer rain helps the grapes grow but it's not all beneficial.
Hartman says, "The rain will increase berry weight so that will bring us more fruit in, at the same time it can water it down."
When it rains during the wine harvest you can tell by the color difference in the wine. Their 2011 Cabernet Franc is a little bit lighter in color than in 2012. That's because Tropical Storm Lee came through the area in 2011 dumping quite a bit of rain. But even when it rains during a harvest, it doesn't mean it's going to be a bad wine.
Rain during the harvest means much more work, either rushing to pick the grapes, or also during the wine making process. Sometimes instead of rushing to pick the grapes, they may wait and let the grapes dry out, and let them stay on the vines longer.
Wine harvesting is already several weeks behind. After a cold spring and rainy summer, vineyards are hoping for drier weather.
Hartman says, "Hopefully we don't get a lot of rain this year, we're hoping for fewer tropical storms and hurricanes"
"We check the weather about 5 times a day I think, just like every farmer does."
Several local wineries have started harvesting some grapes, but they say most are still at least a week or more from being ready.
