Moss turns 39 on January 16 and The Kills guitarist Hince is putting his best foot forward to make the birthday special for her, reported Sun online.
"Jamie has been busy sorting out lots of special treats for Kate's birthday, including a trip for them to visit several wine-tasting lodges in the Napa Valley," a source said.
"He is a huge fan of California and loves the rolling countryside in the region when the sun shines."
The couple, who got married over a year ago, might also indulge in painting and spas.
"It will not be just drinking, though. Jamie also wants them to make use of the local spas and to do some painting with local artists," the source added.
