CiderFest, an event now in its fourth year that celebrates the many uses of apples, will be held on Saturday, with day-long activities at several Island locations.

The Farmers Market will be one of the focal points for the day’s activities. There, from 10 a.m. to 2 p.m., the Island Fruit Club will press more than 1,000 pounds of locally grown apples, “selling the delicious results,” according to Ron Weston, one of the organizers. Apple crisp will also be offered.

Between 10 a.m. and 4 p.m. at the Vashon Senior Center, Vashon’s many different kinds of apples — the Island boasts more than 100 varieties — will be on display and available for sampling. Experts on fruit-growing will also be on hand to identify apple varieties, answer questions or offer advice.

And at the Land Trust Building, the fruit club will host presentations on several fruit-growing topics, from planning an orchard to maximizing pollination. Elizabeth Vogt, president of the club, says the group has worked to provide “an exciting lineup of speakers, designed to inform and enrich your own fruit-growing efforts.”

Then, from 4:30 to 6:30 p.m., Vashon Winery’s Ron Irvine will offer a hard cider tasting at Café Luna, featuring six different ciders from several Puget Sound cideries. Like wine, cider comes in a wide range of styles and flavors, Irvine notes. For $10, customers will be able to sample all six selections.

“Although this year’s CiderFest is smaller in scope than previously, it still promises to offer many tasty opportunities to sample the fruits of Island harvests,” Weston said.
