Opal apples should start shipping in early December.

Yakima, Wash.-based FirstFruits Marketing will donate a portion of all Opal sales to charity through its Youth Make a Difference Initiative, according to a company news release.

Opals, a cross between golden delicious and topaz varieties, are sold exclusively in North America by FirstFruits.

This season’s crop will be marketed with the tagline, “Taste the difference, make a difference.”

Opals are expected to ship through April.

Through the Opal Youth Make a Difference Initiative, FirstFruits provides funding for small, grassroots organizations surrounding youth-led food and agricultural issues.

Fans of Opals can nominate worthy organizations that need support. Last season the Opal Youth Make a Difference Initiative provided funding for Katie’s Krops and five other projects.

“It is really inspiring to see the next generation striving to make a real difference in their communities on issues like hunger and healthy eating, the politics of food distribution, and the importance of community service,” Keith Mathews, FirstFruits’ chief executive officer, said in the release.
