Josh shares some of his favorite picks:

• Domaine Saint Pierre Brut NV. "It's a wildly fizzy, off-dry sparkler that's perfect for after a long day in the sun."

• Crossroads Sauvignon Blanc. "This New Zealand white has super-ripe tangerine and gooseberry flavors that wash across the palate. It leaves the mouth literally swimming in a sea of lip-smacking fruit."

• Hope Estate "Broke" Chardonnay. "This is a perfect wine for people who like rich, toasty, full-throttle Chardonnays. It's a big toasty, buttery wonder of a wine."

• Lookout Mountain Merlot. "It's like a ripe Cabernet Sauvignon minus mouthfuls of tannis. This Merlot is a silky and scented with hints of berry and cherry."

• Cooper Hill Pinot Gris. "This is a guilt-free Pinot Gris. It's a 100 percent organic white wine that's rich, citrusy and elegant."
