Who invented green beer?

Legend has it that the idea of green beer originated in America, not Ireland as you might expect. It’s said that Thomas H. Curtin, the owner of the Schnerer Club in New York, added a few drops of a laundry whitener called “Wash Blue” to beer to celebrate St. Patrick’s Day at a party in 1914.

However, because of the yellowish color of the beer, it turned a green hue instead. Thus, the tradition of the colorful drink was born, although now, we use non toxic food coloring!

Since then, this green colored brew has become synonymous with St. Patrick’s Day. There is even a Green Beer Day, which originated at Miami University in Ohio.

This unofficial holiday is celebrated on the Thursday before spring break at the University.

How to make green beer

Whether you’re hosting a St. Paddy’s Day party, or simply enjoying a cozy night in, special St. Patrick’s Day drinks are a fun way to get into the spirit of of the holiday.

Today, we’ll be making green beer. All you need to make it is your favorite light-colored beer, green food coloring, and a glass or mug.

Pour your beer into a mug, add a few drops of green food coloring, and gently stir until the color is evenly distributed. That’s it! In just moments, you’ll have a pint of green beer ready to enjoy.

What type of beer should I use?

When it comes to choosing the best type of beer for making this drink, light beers such as pilsners, lagers, or light ales work best. Their pale color allows the green dye to shine through brilliantly.

How much food coloring is needed?

A little goes a long way! Start with just a few drops of green food coloring per pint of beer and adjust according to your desired shade of green.

The amount depends on how green you want your beer to be! 1 drop in a 12 ounce glass of light beer will result in a very pale, lime-green color.

Three drops will give you a solid shamrock color. I used 2 drops with 12 ounces of beer to get this color:

More than this gives a darker pine-green shade. Remember, it’s easier to add more color than to take it away, so start conservatively.

Be sure to use liquid food coloring, not gel food coloring, which doesn’t mix as well in cold beer.

Here is the green beer recipe!

Place 1-2 drops of liquid food coloring into a glass or mug. Slowly pour 12 ounces of beer into the glass and gently stir to mix the food coloring throughout the beer.

If you want a darker green color, add more food coloring 1 drop at a time.

That’s all there is to it! You’ve got yourself a festive pint of green beer ready to enjoy for St. Patrick’s Day.
