Expanding its modest selection of teas, Portola Coffee Lab introduces a craft tea house, Seventh Tea Bar at the OC Mart Mix in Costa Mesa. The concept’s name is derived from the traditional Chinese belief that tea is the seventh of the seven necessities. With more than 30 unblended single-estate teas brewed with various methods, Seventh Tea Bar delivers an experience as rich as its sister coffee concepts, Portola Coffee Lab and Theorem slow bar. Owners Jeff and Christa Duggan focus on a unique and thoughtful selection of unblended teas spanning the globe. Offerings also include iced teas on tap and fruit and herb-infused custom creations. Seventh offers various traditional tea services for individuals or groups, complete with Chef-inspired tea sandwiches, scones and pastries. 3313 Hyland Avenue, Costa Mesa, 949.284.0596. seventhtea.com
