They start off normal, then get SO FREAKING HAPPY. Thanks, wine!

Anyone who's ever tasted the sweet nectar of wine knows that it makes everything better. One sip of that fermented grape water, and suddenly you don't owe $30K to the IRS. Your apartment isn't infested with spiders. It's okay that U2 keeps coming on your Pandora station.

Often, the instant delight that wine brings isn't afraid to show itself on your face, a happy little phenomenon that Brazilian photographer Marcos Alberti captured in this life-affirming photo series that shows just how much wine improves one's mood.

Alberti told Telegraph UK, “There is a saying about wine that I really like and it's something like this, ‘The first glass of wine is all about the food, the second glass is about love and the third glass is about mayhem.’ I really wanted to see for myself if that affirmation was in fact true."

He adds: “I started this project because if you search for alcohol on the internet you only can find bad stuff about it. I wanted to show the good side of it – of course, between friends who are drinking responsibly in a good environment. It's like portraits during happy hour.”

Alberti snapped shots of friends when they had drunk one, two and three glasses of wine and these are the amazing results. Go Chianti yourself.
