A multifarious but rarely nefarious array of local wineries, restaurants, artisans, crafters, and entertainers fortifies the stomping grounds at the Grape Harvest Festival, the oldest fete of its kind in California. But the main attraction is, without a doubt, the myriad buckets of squishy, sweet violet spheres waiting for aspirant tap dancers and resentful vegetable farmers to engage in one of the few remaining traditional grape stomps open to the public. Once you've finished gleefully purpling your heels, you'll get to taste the fermented fruits of local labor and celebrate the Rancho Cucamonga community’s vineyard heritage by sampling sips and nibbles from fine neighboring eateries, with each bite soundtracked by live music and other performances populating the various festival stages. Meanwhile, palates preferring motor oil to wine can salivate over the careful craftsmanship and luscious vroom-vrooms of the fest’s Saturday motorcycle rally and Sunday car show, which showcase a wide sampling of motos, including wine-powered Harleys and the rare ’82 vintage Ford Zinfandel. And with more than 100 arts and crafts options, the artsy-flatulentsy of any age can both make and take home handcrafted treasures.
