Remember it’s October 21, 2015
Pepsi Perfect was a vitamin-enriched variety of Pepsi cola that was sold at the Cafe 80’s in 2015. It was sold in bottles that had a lid with a built-in straw. However, when Marty McFly had first seen the soft drinks container, he was perplexed as to how exactly he was supposed to open it.
Doc Brown had given Marty a $50 bill to purchase the soda.
