Don't let that interesting guy intimidate you. Your bagel pizza was just as intriguing as whatever he had for lunch. There's no reason you can't enjoy the same beer he does. Dos Equis was first brewed in Mexico in 1890. It remained within the country's borders for almost 100 years before finally crossing into the US. Because it was founded by a German immigrant, Dos Equis combines traditional beer styles with a Mexican influence for something truly unique.
