Tempra Tantrumis a new line of four tempranillo-based wines introduced by Underdog Wine Merchants. The line was created by a sixth-generation vintner from the Osborne family, Rocío Osborne. The wines are produced in Spain’s Tierra de Castilla region and include a cabernet sauvignon, merlot, shiraz and grenache, all blended with the tempranillo grape. The line is crafted to focus on the fruitiness of the grapes, according to the company.
