Any beer lover traveling to Italy has to sample a Peroni Red once.  No excuses. No opt outs.         

Not because Peroni Red is so damned good.  Peroni just happens to be Italy's signature brewer and Peroni Red its signature brew.          

Don't believe me?  Ask anyone in your own country to name an Italian brew.  If they can successfully do so, Peroni will come up over 80% of the time.  Peroni is the beer which, for whatever reason, got widely exported.  But not Peroni Red.  Although Peroni Red is THE Peroni within the Italian Republic and Italy's best selling brew, it's actually Peroni's Nastro Azzurro which is THE Peroni abroad.  

Peroni is Italy's oldest mainstream brewer, established in Lombardy in 1846 and relocated to Rome in 1846, and if we want to be realistic about it, the beer you're most likely to find in Italy, made with the most 'premium' of ingredients:  barley malt, corn, hop pellets, and hop extract.         

Abroad, Peroni enjoys a much more premium reputation than it actually possesses in its native land.  Peroni abroad is like McDonald's in Asia in the 1980's.        

If you have plenty of beers to choose from, I'd have to question why you'd regularly order a generic Peroni Red over the many more infinitely drinkable brands that really deserve premium reputations.  Unless you're studying Italian, that is.  To learn Italian properly, drinking a Peroni Red is de rigueur before, during, and after any Italian language lesson.
