After 23 years in business, Schlafly Beer is celebrating by brewing a beer that takes both its name and main ingredient from the traditional anniversary gift of that year, Topaz.

To commemorate the occasion, the St. Louis, Mo.-based brewery has released Imperial Topaz IPA, an IPA that is brewed with hops from Tasmania, Australia.

“This Imperial IPA is a light amber color, has a bold but elegant citrus flavor and delicious aroma,” said James Ottolini, Schlafly Beer brewmaster, in a post on the brewery’s website. “We discovered the Topaz hop from a grower on the island of Tasmania, Australia, who supplies the hops for our much loved Tasmanian IPA. When I realized that the gemstone for the 23rd is Imperial Topaz, this became a perfect fit.”

According to the brewery, Imperial Topaz is packaged in 750ml bottles and is now available on draft and in bottles at The Schlafly Tap Room in St. Louis and Schlafly Bottleworks in Maplewood, Mo. In addition, a very limited number of bottles will hit Schlafly’s distribution footprint.
