In celebration of its 20th anniversary, Stone Brewing Co. released a limited-edition celebratory double IPA: Stone 20th Anniversary Citracado IPA, which is brewed with avocado flower honey and Citra hops, the company says. The craft beer also is a part of the brewer’s new Stone Anniversary IPA Collection four-pack, which also includes the Stone 5th Anniversary IPA, Stone 10th Anniversary IPA and Stone 15th Anniversary Escondidian Imperial Black IPA, it says. Designed to thank its craft beer supporters, the throwback anniversary four-pack rolled out in select markets nationwide this month. “We’re excited to close in on two full decades of high-quality brewing,” Stone Chief Executive Officer and Co-Founder Greg Koch said in a statement. “… Fans will be able to relive a bit of Stone history with some of our most beloved Stone Anniversary Ales. This is the first time we’ve rebrewed these IPAs since their debut, and we’re thrilled to provide this very unique opportunity for our fans to relive the past with us.”
