How Coffee Liqueur Is Made | The NORSE CODE Brewing Process
How Coffee Liqueur Is Made
Coffee liqueur is usually made by combining coffee, alcohol, sugar and water — but the quality of the final drink depends heavily on how the coffee is selected, brewed and blended.
At NORSE CODE, coffee liqueur is not treated as a sweet spirit with coffee flavour added afterwards. It begins with freshly brewed coffee and a brewing process developed by Gordon Howell, drawing on more than 30 years of experience across coffee, hospitality, training, judging, competition and beverage development.
This guide explains how coffee liqueur is made, why brewing method matters, and how the NORSE CODE process differs from many mainstream coffee liqueurs.
What Is Coffee Liqueur Made From?
Most coffee liqueurs contain four core elements:
- Coffee or coffee flavour
- Alcohol
- Sugar or syrup
- Water
That sounds simple, but there is a huge difference between a liqueur made with real brewed coffee and one made using concentrates, extracts or flavourings. The coffee source, extraction method, sugar balance and spirit integration all affect the final flavour.
Common Ways Coffee Liqueur Is Made
Different producers use different methods depending on cost, scale, flavour goals and production style.
1. Coffee Flavourings
Some coffee liqueurs rely heavily on flavourings rather than freshly brewed coffee. This can create a recognisable coffee note, but it often lacks the depth, aroma and complexity of real coffee.
2. Coffee Concentrates
Concentrates are widely used because they are convenient, consistent and easy to scale. The trade-off is that they can taste flat, processed or overly sweet once blended into alcohol and sugar.
3. Coffee Maceration
Maceration involves soaking coffee in alcohol. It can create intensity, but it may also extract bitterness, harsh roast notes or astringency if not controlled carefully.
4. Hot Brewing
Hot brewing can extract coffee efficiently and produce bold flavour. Used well, it can create body and intensity. Used poorly, it can pull through bitterness and harshness that become more noticeable in a liqueur.
5. Lower-Temperature Filter Brewing
NORSE CODE uses a controlled lower-temperature filter brewing process rather than simply using near-boiling water or cold-water immersion. This approach was developed by Gordon Howell specifically for coffee liqueur production.
The aim is not to extract the maximum possible amount from the coffee. The aim is to extract the right balance of flavour for a finished spirit.
The NORSE CODE Brewing Process
NORSE CODE starts with freshly brewed coffee, not artificial coffee flavouring. Gordon Howell developed the brewing approach to suit the needs of coffee liqueur rather than copying a brewing recipe designed for drinking coffee on its own.
Coffee brewed for a cup and coffee brewed for a spirit have different requirements. A filter coffee may taste excellent on its own, but once alcohol, sugar and dilution are introduced, bitterness, acidity, body and aroma behave differently.
That is why NORSE CODE uses a dedicated brewing method designed for balance, clarity and cocktail performance.
Why Brewing Temperature Matters
Brewing temperature affects how coffee extracts. It can influence:
- Bitterness
- Acidity
- Sweetness perception
- Body
- Aroma
- Aftertaste
- How the coffee integrates with alcohol
A common assumption is that stronger extraction always creates better coffee flavour. In coffee liqueur, that is not always true. Over-extraction can create bitterness and astringency that are magnified by alcohol.
The NORSE CODE process is designed to preserve coffee character while reducing the harsher notes that can make some coffee liqueurs taste burnt, bitter or overly heavy.
Developed By Gordon Howell
The NORSE CODE brewing process was developed by Gordon Howell, one of the UK’s most experienced coffee professionals.
Gordon’s background includes more than 30 years across coffee and hospitality, including UK Brewers Cup Champion, World Brewers Cup finalist, Coffee in Good Spirits competitor, coffee trainer, competition judge and co-founder of Tone Brewing Equipment.
That experience matters because coffee liqueur is not just about adding coffee flavour to alcohol. It is about understanding extraction, balance, sweetness, bitterness, texture and how coffee behaves in cocktails.

Why NORSE CODE Does Not Chase Maximum Extraction
In coffee, more extraction does not automatically mean better flavour. The wrong extraction can pull out bitterness, dryness and heavy roast notes.
For NORSE CODE, the goal is balance. The coffee needs to stand up in an Espresso Martini, layer properly in a Baby Guinness, and still taste clean when served simply over ice.
That requires a different approach from coffee brewed only for immediate drinking.
How The Coffee Is Blended Into Liqueur
Once the coffee element is prepared, it is blended with spirit, sugar and water to create the finished liqueur. This stage affects mouthfeel, sweetness, strength and cocktail performance.
Hel Above and Hel Below are built differently because they are designed for different jobs.
Hel Above
Hel Above is 22% ABV and designed for cocktails such as the Espresso Martini, where coffee intensity, structure and foam matter.
Hel Below
Hel Below is 16% ABV and designed with greater density for Baby Guinness serves, while still working well in Espresso Martinis and other coffee cocktails.
Why This Matters In The Glass
The brewing and blending process affects how a coffee liqueur performs in real serves.
A good coffee liqueur should deliver:
- Clear coffee flavour
- Balanced sweetness
- Clean finish
- Reliable cocktail performance
- Enough structure to stand up against other ingredients
- Consistency from batch to batch
That is why NORSE CODE focuses on brewing, not just flavouring. The coffee is not an afterthought — it is the foundation of the product.
Is NORSE CODE Cold Brew?
Not exactly. NORSE CODE is not made by simply steeping coffee in cold water for many hours like a traditional cold brew.
The better description is a controlled lower-temperature filter brewing process developed specifically for coffee liqueur. It uses filter brewing principles, but at a lower brewing temperature than conventional hot filter coffee.
This helps create a cleaner coffee profile with reduced harshness and better balance in the finished liqueur.
How Coffee Liqueur Should Taste
Many people are used to coffee liqueurs that taste mainly of sugar, caramel and generic coffee flavour. NORSE CODE takes a different approach.
The aim is for the coffee to remain recognisable, structured and balanced. Sweetness is important, but it should support the coffee rather than cover it.
That difference is especially noticeable in cocktails where the coffee liqueur is not hidden. In an Espresso Martini, Baby Guinness or simple serve over ice, the quality of the coffee and the brewing method become obvious.

Frequently Asked Questions
How is coffee liqueur made?
Coffee liqueur is usually made by combining coffee or coffee flavour with alcohol, sugar and water. The quality depends on the coffee used, the brewing or extraction method, the spirit base and the balance of sweetness.
Does NORSE CODE use real coffee?
Yes. NORSE CODE begins with freshly brewed coffee rather than relying on artificial coffee flavour alone.
Is NORSE CODE cold brew coffee liqueur?
Not in the traditional cold brew sense. NORSE CODE uses a controlled lower-temperature filter brewing process, developed specifically for coffee liqueur production.
Who developed the NORSE CODE brewing process?
The process was developed by Gordon Howell, drawing on more than 30 years of experience across coffee, hospitality, training, judging, competition and beverage development.
Why does brewing temperature matter in coffee liqueur?
Brewing temperature affects bitterness, acidity, body, aroma and how the coffee integrates with alcohol and sugar. The right extraction helps create a cleaner, more balanced liqueur.
What makes NORSE CODE different from mainstream coffee liqueurs?
NORSE CODE is built around freshly brewed coffee, a dedicated brewing process and cocktail performance. It is designed to showcase coffee character rather than simply adding generic coffee flavour to a sweet liqueur.
