St. Patrick’s Day is all about green beer, shots of whiskey, and Guinness-fueled parties, but have you ever wondered how a holiday for Ireland’s patron saint turned into one of the biggest drinking days of the year?

The truth is, the way we celebrate St. Patrick’s Day has more to do with Irish-American culture than with the actual traditions from Ireland. This holiday’s journey shows the complicated connection between Ireland, its people around the world, and the drinking customs that have evolved over time.

Let’s dive into the surprising and fun history of March 17.


1. Dry St. Patrick’s Days Until the 1960s!

You might be shocked to learn that for much of Ireland’s history, St. Patrick’s Day was actually a dry holiday.

So, How Did That Happen?

  • St. Patrick’s Day is a Catholic feast day, and for years, it was a serious religious day in Ireland.
  • From 1903 to 1961, Irish law said all pubs had to close on March 17, so what is now the biggest drinking day was completely alcohol-free in its home country!
  • The only places serving drinks? Hotels, meaning packed bars in hotels while regular pubs stayed closed.

When Did This Change?

The 1960s brought a cultural shift in Ireland. As the country modernized, they lifted the pub ban in 1961. Ever since, St. Patrick’s Day turned into a major drinking occasion in Ireland and around the world.


2. Why Guinness is the St. Paddy’s King

You can’t mention St. Patrick’s Day drinking without talking about Guinness, the go-to drink for March 17.

How Much Guinness is Drank on St. Patrick’s Day?

  • About 13 million pints of Guinness are consumed globally on March 17, which is double what they sell on a normal day.
  • In the U.S. alone, over 3 million pints are poured, making it one of the biggest beer days of the year.

Why is Guinness the Drink of St. Patrick’s Day?

  • Guinness started brewing back in 1759 at St. James’s Gate Brewery in Dublin. By the 19th century, it had become Ireland’s favorite beer.
  • With millions of Irish immigrants in the U.S., they brought their love for Guinness with them.
  • Irish pubs in America used Guinness to celebrate their heritage, and as the celebrations grew with parades and pub crawls, Guinness became the unofficial drink of the holiday.

Today, even those who don’t usually drink Guinness tend to order a pint on March 17, keeping this centuries-old Irish beer at the heart of the festivities.


3. Green Beer? Thanks, American Dentist!

While purists stick to Guinness, green beer is more of an American twist that’s been around for over a century.

Who Came Up with Green Beer?

  • Green beer wasn’t a thing in Ireland; it originated in New York City in 1914.
  • Dr. Thomas Curtin, who was a coroner and part-time doctor, dyed beer green for a St. Patrick’s Day party in the Bronx.
  • His secret? A laundry whitener with blue dye – not the most appetizing mix!

How Did Green Beer Get Popular?

  • The trend took off in Irish-American communities, and by the 1950s, bars across the U.S. were using food coloring to make their beer green.
  • It became a big part of St. Patrick’s Day, especially in places like Chicago, where they even dye the Chicago River green to celebrate the holiday.

While many bartenders might not be fans of green beer, it’s still a fun tradition for millions who celebrate St. Paddy’s Day.


4. Whiskey and St. Patrick’s Day: A Classic Combo

While beer takes the spotlight, Irish whiskey is also a key player in St. Patrick’s Day.

The “Drowning the Shamrock” Ritual

  • There’s an old Irish custom of dropping a shamrock into the last drink of the night, toasting to good luck, and then tossing it over your shoulder.
  • This “drowning the shamrock” tradition goes back centuries and is one of the few St. Patrick’s Day customs that actually started in Ireland.

The Role of Irish Whiskey Today

  • Brands like Jameson, Bushmills, and Tullamore D.E.W. have made whiskey a favorite drink for March 17.
  • Nowadays, whiskey shots and Irish coffee are as common as Guinness, making whiskey a staple in St. Patrick’s Day celebrations.

Final Thoughts: What St. Patrick’s Day Drinking Is Really About

Even though today it’s seen as a day of indulgence, the drinking traditions of St. Patrick’s Day are tied to Irish immigration, American creativity, and the holiday’s ever-changing identity.

So here’s the quick scoop:

  • ✅ St. Patrick’s Day drinking started in America, not Ireland.
  • ✅ Guinness became the “king of St. Paddy’s” thanks to Irish immigrants.
  • ✅ Green beer? That was invented by an eager dentist in the U.S.
  • ✅ Authentic touches like Irish whiskey and the “drowning the shamrock” tradition still keep the spirit alive.
