Women-owned Siren Shrub Co. announced teaming up with award-winning Ruby Coffee Roasters to release its new coffee drink: Coffee Sparkling Shrub. The flavor, inspired by the Espresso Romano, is a combination of lemon juice and espresso, the company notes. The team at Siren Shrub Co. decided to swap in the apple cider vinegar mixer to naturally replicate the acidity of lemons, it says. The Siren Shrub Co. Coffee Sparkling Shrub boasts nutty notes of citrus and berry – with a little something extra, it adds. This limited edition collaboration is available to purchase online and in stores for $20.00 for four 12-ounce cans or as part of a four-pack sampler.
