What is the history of the layered beer cocktail?

​The "black and tan" beer cocktail, typically made by layering a pale ale (often Bass Ale) with a dark stout (commonly Guinness), has become a well-known drink in modern bars, especially in the United States and the United Kingdom. However, its roots and usage in the 18th century were notably different from its contemporary presentation.

Beer Blending
In the 18th century, beer blending was common in Britain and Ireland, but the specific term "black and tan" and the popularized modern version were not yet in use. Instead, patrons and publicans frequently mixed various types of beers, ales, and porters to adjust flavor, strength, and freshness. This practice stemmed from the inconsistent quality of beer and the desire to customize drinks to taste.

Drinks like "three-threads" or "half-and-half" were typical mixtures that might include a young ale, an older, more mature ale, and a porter. These blends eventually contributed to the invention of porter itself in the early 18th century, which was a pre-mixed version of such combinations.


Origins and Early Layered Beers
The concept of a layered beer drink, with the visual contrast seen in today’s black and tan, was less of a focus in the 18th century. The layered effect requires precise pouring techniques and beers with specific gravities, which were not typically emphasized or standardized at the time.

Therefore, while mixing beers was indeed a common and practical practice in the 18th century, the specific cocktail known as a "black and tan," especially in its aesthetic presentation, did not emerge until much later, likely in the late 19th or early 20th century.


The term "Black and Tan" originally referred to the contrasting colors of the two beers, but it later became associated with a controversial paramilitary force in Ireland, making the name politically sensitive in some regions.

Other Classic Layered Beers
Aside from the Black and Tan, several other layered beer cocktails emerged over time, such as:
Half and Half – Similar to a Black and Tan, but typically using a lighter lager instead of pale ale.
Black Velvet – A mix of stout and sparkling wine, originating in Victorian England to mourn the death of Prince Albert in 1861.
Snakebite – A blend of beer and cider, sometimes layered, that became popular in British pubs in the 20th century.

The Science of Layering Beers The key to a successful layered beer cocktail is the difference in specific gravity (or density) between the two beers. Light-colored beers with a higher density, such as pale ales or lagers, sit at the bottom, while lower density nitro-stouts (ie. Guinness Draught) float on top when poured correctly over the back of a a layering tool or spoon. This technique creates the signature divided look of layered beer drinks.  See our Instructions Page for more details.

Modern Variations and Popularity Layered beer cocktails have gained renewed popularity in craft beer culture, with bartenders and beer enthusiasts experimenting with new combinations. Some modern variations include seasonal or themed versions, such as adding green food dye to a Black and Tan for St. Patrick's Day or using flavored stouts for a unique twist.

The tradition of layered beer cocktails remains a fun and visually appealing way to enjoy different beer styles in a single glass while honoring a long-standing pub tradition. 🍻

Have you tried Guinness Zero (Non-Alcoholic)?

I recently received an email from Daniel. He has been following our blog for a while. He said that he has been mostly sober for 4 years now but still enjoys the taste of a black & tan. For this he's been using Guinness Zero Draught instead of the regular Guinness Draught.

He's found that NA Guinness & Blue Moon work the best.  Below are photos of his drinks from the past year.  He said "It has been fun trying various NA beers. I realize I am a very small subset of an already small niche of beer drinkers, but thought you might be interested to see that even teetotalers like me can still enjoy a good brew."

​Thanks for the email Daniel!

What? Green beer?

Yes! There are green layered beers, especially for St. Patrick’s Day. The most common way to create them is by adding green food coloring to the lighter layer of a traditional layered beer cocktail, such as a Black and Tan or a Half and Half (Guinness and Harp).
Here are a few examples of green layered beers:
  1. Green and Black (Green Half & Half) – A twist on the classic Half and Half, where Harp Lager (or another pale lager) is dyed green before layering Guinness on top.
  2. Green and Gold – A combination of a green-colored pale ale or lager and a darker amber or red ale layered on top.
  3. Emerald Stout – Green-dyed cider or wheat beer on the bottom with a stout like Guinness on top.
The key to achieving a clean layer is using beers with different densities, just like a traditional Black and Tan. Have you ever tried making one?

How to Make a Black and Tan Layered Beer with Green Food Dye for St. Patrick’s Day

2/20/2025

St. Patrick’s Day is all about celebrating Irish culture with good company, great food, and of course, festive drinks! One classic beer combination that stands out is the Black and Tan—a beautifully layered mix of a pale beer and a dark stout. This year, why not take the festivity up a notch by adding a splash of green to the mix? Here’s how to make a St. Patrick’s Day-inspired Black and Tan with green food dye.

What You’ll Need:
- A light beer (such as a pale ale, lager, or pilsner)
- A dark stout (traditionally Guinness, but any stout will work)
- Green food coloring
- A layering tool (preferably a Perfect Black and Tan layering tool for better layering)
- A pint glass

Step-by-Step Instructions:
1. Prepare the Green Base
Start by filling your pint glass about halfway with your light beer. Add 1-2 drops of green food coloring to the beer and gently stir until the color is evenly mixed.
2. Layer the Stout
The key to a perfect Black and Tan is layering. Place the layering tool over the glass and slowly pour the stout over the tool. This technique helps the stout settle on top of the green beer rather than mixing with it. The lower density of the stout will naturally keep it floating above the heavier bottom beer, creating a distinct two-tone effect.
3. Admire Your Creation
Once the pour is complete, you should see a striking contrast between the dark stout and the vibrant green base. Let the colors settle for a moment before taking a sip.

Tips for the Perfect Black and Tan:
- Add the dye slowly to get just the right amount of green color. Some dyes may be more concentrated than others.
- Pour the stout slowly to maintain a clean separation between the layers.
- If you don’t have a layering tool, you can use a Guinness spoon or even a steady hand with a gentle pour.
- The lighter the beer, the more vivid the green color will appear.
- Serve in a clear pint glass to fully appreciate the festive effect.

​This St. Patrick’s Day, impress your guests with this festive twist on a classic drink. Cheers to good times and great beer—Sláinte

Sharing Some Black and Tan Beers Before St. Patrick's Day

Below are some layered beer pictures that I've posted on Instagram but thought I would share here. I've separated the pictures into Guinness on Top and Dark on Bottom.
GUINNESS ON TOP COMBINATIONS:
The first picture with Guinness over a Legal Draft Smash & Grab IPA worked out really well. Excellent black and tan layer separation and the cloudy nature of the IPA makes the overall look even better.
DARK ON BOTTOM COMBINATIONS:
Check out the Stella on Stella combo with their new Midnight Lager layering under the classic.

The Impossible: A Seven Layer Beer!!

Dave from Minnesota sent me this picture of a 7 layer beer. This is amazing.

He told me that this was the culmination of much "research" and the "Perfect Black & Tan" tool. Dave told me that "Surprisingly, the seven layer came together with only one small "test" between two of the lighter beers. That being said, there were a lot of two, three and four layered past combos that made the seven layer happen. Besides drinking it, the best part was that the layers stayed in tact while drinking, and got thinner and thinner until it was gone. "

Thanks for the picture Dave. You are the beer layering king!
