Blake Shelton and Gwen Stefani are making the most of their holiday season!
One day after taking in a football game in Arizona, the cute couple were spotted wine tasting in Buellton, California.
A source tells ET that Shelton and Stefani went on a half-hour guided wine tour at Mosby Winery, along with another couple.

The Voice co-stars enjoyed a selection of the winery's Italian offerings, including a Pinot Grigio. The source shared that the couple were "delightful" to the staff and "seemed very happy together."
The Winery later shared a photo of Stefani standing with manager Louise Smith, along with a message of gratitude for the couple's visit.
"Mosby Winery had the distinct privilege of hosting Gwen Stefani & Blake Shelton along with 2 of their friends today! What an absolute treat!" the Winery's Facebook post read. "They were so wonderful, sweet & just great people... Thank you so much for visiting & I hope to see you again!"
One fellow wine-taster also snapped a pic of the 39-year-old country crooner at the winery, which they shared to Instagram.

Meanwhile, Shelton's ex, Miranda Lambert, seems to have moved on as well. A source recently told ET that the 32-year-old GRAMMY winner is dating 27-year-old singer Anderson East.
Lambert also shook things up on Christmas Eve when she began following Stefani on Twitter, just in time to catch some of the 46-year-old No Doubt singer's PDA-filled pics with Lambert's ex.
