At the center of a big, round table sits a lazy susan bearing tiny, elegant white dishes. Each holds a mound of intriguing dried leaves that look as though they’ve been emptied from an alchemist’s vial. Over the course of the evening, everyone around the table will watch, smell, and taste as the power of those leaves is awakened through hot water and the deep knowledge shared by Roberta, Experience Tea’s owner. A certified tea specialist, she leads classes on a vast range of tea topics, exploring everything from health benefits to proper steeping techniques to the etiquette of Chinese tea ceremonies or British-tea hot tubs. Within a warmly lit storefront lined by painted brick walls and a veritable library of tea varieties, students can also learn how to create their own signature brew in blending workshops. Even customers who stop in for a pouch of loose-leaf are likely to end up indulging in a rich sensory experience as Roberta offers them a sample and shares tasting notes.
