Final answer:
The exact year Starbucks introduced espresso beverages is not provided, but coffeehouses have a rich history beginning in 17th-century Europe, with Starbucks representing the modern evolution of these establishments.
Step-by-step explanation:
The year that Starbucks introduced espresso beverages to customers is not explicitly stated in the provided materials, so it's not possible to provide a specific answer to that question. However, I can provide a brief historical context of coffeehouses and mention Starbucks as part of the modern coffee culture. Coffeehouses have a long tradition, dating back to the 17th century in Europe. For instance, they rose in popularity in London and Paris, with the first coffeehouse in Venice opening in 1645. They became centers for socializing and were at times scrutinized by authorities for stoking dissent. The first coffeehouse in Vienna opened thanks to Jerzy Franciszek Kulczycki, who brought his knowledge of coffee from his time as a prisoner of war in Turkey.
Starbucks, on the other hand, has become synonymous with modern coffee culture, offering a wide range of caffeine-infused drinks like espresso, plain brewed coffee, and other specialty beverages. The company became notable for popularizing certain types of coffee drinks and the experience associated with them.
