Julie’s Organic, Eugene, Ore., said it is celebrating its 20th birthday with a limited-edition box design for its flagship product and consumer giveaways. The brand debuted the first nationally available organic ice cream in 1998, long before organic food would become a $45.2 billion industry, and four years before USDA organic standards were even established.

To honor the milestone, Julie’s vanilla ice cream sandwich — the company’s leading product and the best-selling organic novelty in the U.S. natural channel, according to SPINS — is showcasing a limited-edition commemorative 20th Anniversary box. The packaging features high-resolution photography and elements of purple and gold, highlighting the brand’s premium quality and sophisticated taste, the company said.

“Our fans seek out Julie’s because they know that our products don’t force them to choose between clean ingredients and great taste,” said Michelle Hunt, vice president of marketing at Julie’s Organic. “They know that with Julie’s they can have a treat made with clean and simple ingredients, and without the things they’re trying to avoid, like high fructose corn syrup, carrageenan and artificial sweeteners. We are grateful to our fans for 20 years of support.”

To honor fans’ loyalty and enthusiasm, Julie’s is inviting fans to celebrate their own birthdays with giveaways throughout the summer. The giveaways will be hosted on the brand’s Facebook and Instagram pages, and prizes will include free ice cream, limited-edition enamel pins and other exclusive gear, the company said.

In addition to its original ice cream sandwiches, Julie’s offers 11 pints, eight bars and three mini sandwiches. The brand’s products are all certified organic and come from cows not treated with the artificial growth hormone rBST or antibiotics, no artificial ingredients or high-fructose corn syrup, and no high-intensity sweeteners (such as erythritol) that are typically found in low-calorie ice creams.
