In my opinion, February and October are the best months for the wineries in California – in terms of the beautiful photo opps.  February, thanks to the yellow mustard plants covering entire fields – the color contrast most welcoming against the bare blackened vines. October is harvest season, when the grapes are robust and deep variations of purple, and maroon, some even tranquil shades of green – intertwined with the changing Autumn colors of the leaves. So, naturally you have to plan a trip to California to see unique and some of the  most beautiful wineries: Sunstone Winery
