Making Beer Green Without Food Coloring ~ Here Is How You Do It ~

Green Beer

Beer is one of those drinks that you can enjoy during a holiday or celebration. Speaking of celebration, St. Patrick’s Day is just around the corner.

For many festive planners, the last point usually involves a grocery trip to load up beers and all festive paraphernalia.

It is also good timing to find ingredients that will turn your beer green, following the festival’s green theme.

How do you make beer green without food coloring? Pour wheatgrass juice, spirulina powder, or matcha powder into your beer glass. Then you can pour beer on top, and you will end up having different variations of green color in your beers.

In today’s post, you will find ways to turn your classic beer into one of those festive green beers that work at every St. Patrick’s celebration.

Natural Coloring for Beer

As mentioned above, St. Patrick’s is one of those festivities where beer is the centerpiece. It is all about beer, and what a way to stick with the color theme than to have a green beer?

But this time, no more food coloring. Kick-off your celebration in style with creative ways to turn your beer into a green drink. 

Wheatgrass Juice

Wheatgrass juice is the best coloring that you can try, as it is a beautifully bright yellow-green. It looks similar to the result you will get using artificial food coloring and it dyes your beer pretty evenly.

The good thing about this food coloring method is that it does not make your beer cloudy, and the wheatgrass juice dissolves properly.

It is the most pronounced but not the bad kind of way in terms of flavor. If you have never tried wheatgrass before, it tastes exactly like what you’d think—a little grassy.

Just use a small amount, so it does not overpower the beer. It can add a grassy undertone to the overall flavor of your beer.

You can pretty much get a juice bar in your local supermarket, or another option is to use wheatgrass to make your own juice.

Many supermarkets sell them either pre-cut or in pots, and they are usually in the product section.

To use wheatgrass juice in your beer, pour 1 tablespoon of wheatgrass in the bottom of your beer glass.

Then pour your beer over the top and add some more wheatgrass juice a bit at a time until you reach the desired color.

Spirulina Powder

Spirulina powder can leave you with more of a teal or hunter green color, regardless of how much you use.

It is potent stuff for coloring, so a little goes a long way. It dyes your beer in a darker hue, and it dyes the top well too.

For flavor, you can expect some taste, which takes some getting used to. This is because spirulina is a type of algae, which means it has a slightly fishy and metallic taste.

With just small doses and a strong beer, it is not bad, but if you add too much spirulina, you will be pouring your green in the sink.

As with wheatgrass juice, you can get it at your local grocery store but if you want a particular location, try the healthy local food store.

There will probably be a bulk spices section there, and chances are, you will see a teal green powder labeled as spirulina.

As mentioned, you do not need a lot, so use smaller doses like a half teaspoon per beer.

If you are mixing it with your beer, you can put ½ teaspoon of spirulina in a small bowl, or you can pour it directly into the bottom of your beer glass.

Add a few tablespoons of beer and then, using a small whisk, whisk the powder until it is completely dissolved.

Finally, you can add the remainder of your beer. At this point, you can see your beer turning darker green.

Matcha Powder

Matcha powder is the last food coloring in this article, and you can expect it to create a deep olive green color.

This is not the bright Irish green you are looking for, but it is still on the green side. However, it can cloud your beer a little, and sometimes it does not mix perfectly well.

You should use matcha powder if you want the least impact on flavor. If you have never had matcha-flavored food before, it is a powdered green tea, and a lot of people love this taste.

If you are still curious about what it really tastes like, it has a bit of a vegetable taste like spinach but not overpoweringly so.

If you add it to a beer that has a flavor, you won’t really taste it at all. 

Matcha powder has been getting popular on social media, and you can get it everywhere, including online and in your local grocery stores.

Matcha powder can be found in some tea shops as well, so if you are looking for one, you might find it there.

To mix it with your beer, 1 teaspoon of matcha powder in a small bowl, or you can put it directly in the bottom of your beer glass.

Then add a few tablespoons of the beer and whisk them properly until they are dissolved. This can take a while, so you need patience on this one. Afterward, you can pour it in your beer and enjoy!


There are plenty of ways to colorize your beer depending on how you want it to taste. These are the most common natural food colorings for you to try, as they deliver in terms of coloring.

Speaking of coloring, you also need to consider the taste. Your beer might be green, but it could also be undrinkable, so choose wisely.
