DIY Finnish Long Drink (Lonkero): The Ultimate Guide to Making Your Own!

Lonkero, also known as Finnish Long Drink, is a refreshing and iconic beverage that holds a special place in Finnish culture. Traditionally, it’s a mix of gin and grapefruit soda, but its simplicity belies its satisfyingly tart and bubbly character. If you’re craving a taste of Finland but can’t easily find it in stores, don’t worry! This comprehensive guide will walk you through everything you need to know to create your own delicious and authentic Finnish Long Drink at home.

What is Lonkero? A Brief History

The story of Lonkero begins with the 1952 Summer Olympics held in Helsinki. Hartwall, a Finnish beverage company, was tasked with creating a pre-mixed drink that could be easily served to the large influx of tourists. The result was Gin Long Drink, a concoction of gin and grapefruit soda, served in a long glass (hence the name “long drink” or “lonkero” in Finnish).

The drink was an instant hit, both with tourists and locals. After the Olympics, Hartwall continued to produce Lonkero, and it quickly became a staple in Finnish bars and restaurants. Today, Lonkero is more than just a drink; it’s a symbol of Finnish identity and summer relaxation.

Why Make Your Own Lonkero?

While commercially produced Lonkero is available in some countries, it’s not always easy to find. Even when you do find it, the taste might differ from the original Finnish recipe. Here are a few compelling reasons to make your own:

* **Authenticity:** You can control the ingredients and ratios to create a Lonkero that tastes just like the real thing.
* **Customization:** Experiment with different gins and grapefruit sodas to find your perfect flavor combination.
* **Cost-Effective:** Making your own Lonkero can be more affordable than buying pre-mixed versions, especially if you plan on enjoying it regularly.
* **Fun and Easy:** The recipe is simple and straightforward, making it a fun and rewarding project for any home bartender.
* **Impress Your Friends:** Introduce your friends to this unique and delicious drink and impress them with your newfound cocktail-making skills.

Essential Ingredients for DIY Lonkero

To make authentic Lonkero, you’ll need the following ingredients:

* **Gin:** The base of Lonkero is gin. London Dry Gin is the most traditional choice, as its dry and juniper-forward flavor profile complements the tartness of the grapefruit soda. However, you can experiment with other types of gin, such as New Western or floral gins, to create a more unique flavor.
* **Grapefruit Soda:** This is the key ingredient that gives Lonkero its signature tart and bubbly taste. Look for a high-quality grapefruit soda that is not overly sweet. Examples of good choices include:
* **Hartwall Original Long Drink Grapefruit Soda (if available):** This is the authentic Finnish soda used in the original Lonkero recipe. If you can find it, it’s the best option for achieving the true Finnish flavor.
* **Fentimans Pink Grapefruit Tonic Water:** This tonic water offers a unique twist with a slightly bitter and floral undertone, adding complexity to your Lonkero.
* **Schweppes Pink Grapefruit Soda:** Widely available, it provides a good balance of sweetness and grapefruit flavor. However, be mindful of its higher sugar content compared to other options.
* **Jarritos Toronja (Grapefruit):** A Mexican grapefruit soda known for its natural flavors and less sweetness.
* **Other Grapefruit Sodas:** If you can’t find any of the above, look for a grapefruit soda with a strong grapefruit flavor and minimal artificial sweeteners. Avoid sodas that are overly sweet or have a pronounced artificial taste.
* **Lemon or Lime Wedge (Optional):** A squeeze of fresh lemon or lime juice can add an extra layer of tartness and complexity to your Lonkero.
* **Ice:** Essential for chilling your drink and keeping it refreshing.

Equipment You’ll Need

* **Highball Glass:** A tall glass is the traditional serving vessel for Lonkero.
* **Jigger or Measuring Spoons:** For accurately measuring the gin and grapefruit soda.
* **Bar Spoon:** For gently stirring the drink.
* **Citrus Juicer (Optional):** If you plan on adding fresh lemon or lime juice.

The Classic Lonkero Recipe: Step-by-Step Instructions

This recipe creates a classic Lonkero that captures the authentic Finnish flavor. Follow these steps for the perfect result:

**Ingredients:**

* 1.5 oz (45 ml) London Dry Gin
* 4 oz (120 ml) Grapefruit Soda (Hartwall Original Long Drink Grapefruit Soda preferred)
* Lemon or Lime wedge (optional)
* Ice

**Instructions:**

1. **Chill Your Glass:** Place your highball glass in the freezer for a few minutes to chill it. This will help keep your Lonkero cold for longer.

5. **Stir Gently:** Use a bar spoon to gently stir the drink until the gin and grapefruit soda are well combined. Avoid over-stirring, as this can cause the drink to lose its carbonation.
6. **Garnish (Optional):** Squeeze a lemon or lime wedge over the drink and drop it into the glass.
7. **Serve Immediately:** Enjoy your homemade Finnish Long Drink!

Variations and Customizations

The classic Lonkero recipe is a great starting point, but feel free to experiment and customize it to your liking. Here are a few ideas:

* **Adjust the Gin-to-Soda Ratio:** Some people prefer a stronger or weaker drink. Adjust the amount of gin and grapefruit soda to find your perfect balance. Start with the classic ratio and then experiment with increasing or decreasing the gin or soda by 0.5 oz (15 ml) increments.
* **Try Different Gins:** Experiment with different types of gin, such as New Western or floral gins, to create a more unique flavor. For example:
* **New Western Gin:** These gins have less juniper and more citrus or floral notes. They can add a softer, more aromatic flavor to your Lonkero.
* **Floral Gin:** These gins have a pronounced floral aroma and flavor. They can add a delicate and sophisticated touch to your Lonkero.
* **Barrel-Aged Gin:** These gins are aged in oak barrels, which gives them a warm, spicy flavor. They can add a unique depth and complexity to your Lonkero.
* **Add Fresh Fruit:** Muddle a few fresh berries, such as raspberries or strawberries, in the bottom of the glass before adding the ice and other ingredients. This will add a fruity sweetness and aroma to your Lonkero.
* **Spice It Up:** Add a dash of bitters, such as Angostura or orange bitters, for a more complex flavor. Start with just a dash or two, as bitters can be quite potent.
* **Make It Sparkling:** Add a splash of sparkling wine or Prosecco for a bubbly and celebratory Lonkero. This is a great option for parties or special occasions.
* **Herbal Infusion:** Infuse your gin with herbs like rosemary or thyme for a unique aromatic twist. Simply add a sprig of the herb to your gin bottle and let it sit for a few days before using it to make your Lonkero.
* **Frozen Lonkero:** Blend all the ingredients with ice for a refreshing frozen Lonkero, perfect for hot summer days.

Tips for Making the Best Lonkero

* **Use High-Quality Ingredients:** The quality of your ingredients will directly impact the taste of your Lonkero. Choose a good-quality gin and a grapefruit soda with a strong, natural flavor.
* **Don’t Over-Stir:** Over-stirring can cause the drink to lose its carbonation. Stir gently just until the ingredients are combined.
* **Serve Ice Cold:** Lonkero is best served ice cold. Chill your glass and use plenty of ice.
* **Experiment with Garnishes:** While a lemon or lime wedge is the traditional garnish, feel free to experiment with other options, such as a grapefruit slice, a sprig of rosemary, or a few fresh berries.
* **Taste and Adjust:** The most important tip is to taste your Lonkero and adjust the ingredients to your liking. Don’t be afraid to experiment until you find your perfect recipe.

Finding the Right Grapefruit Soda Alternative

As mentioned, Hartwall Original Long Drink Grapefruit Soda is the gold standard. However, finding it outside of Finland can be challenging. Here’s a breakdown of alternatives and their characteristics:

* **Fentimans Pink Grapefruit Tonic Water:** Leans towards a more sophisticated, less sweet profile. It has a distinct tonic water bitterness that some may find adds complexity. It’s a good choice if you prefer less sugar and a more refined flavor.
* **Schweppes Pink Grapefruit Soda:** A more common and readily available option. It’s sweeter than Fentimans and has a more pronounced artificial flavor (though still acceptable). Adjust the gin ratio slightly to compensate for the sweetness.
* **Jarritos Toronja (Grapefruit):** A Mexican soda that uses real sugar and natural grapefruit flavor. It’s less sweet than many other grapefruit sodas, making it a closer substitute to the original Finnish soda. Look for it in Mexican grocery stores or online.
* **Making Your Own Grapefruit Soda:** For the truly adventurous, you can make your own grapefruit soda! This allows for complete control over the sweetness and ingredients. Recipes can be found online using fresh grapefruit juice, simple syrup, and carbonated water.

When choosing an alternative, consider your personal preference for sweetness and the availability of the product. Experimentation is key to finding the perfect substitute.

* **Grilled Meats:** Lonkero also pairs well with grilled meats, such as chicken, pork, or steak. The tartness of the drink complements the smoky flavors of the grill.

Beyond the Basics: Advanced Lonkero Techniques

For those who want to take their Lonkero game to the next level, here are some advanced techniques to consider:

* **Fat-Washed Gin:** Fat-washing is a technique where you infuse gin with a fat, such as coconut oil or bacon fat, to add flavor and texture. To fat-wash gin, melt the fat of your choice, combine it with the gin, and let it sit for a few hours. Then, freeze the mixture until the fat solidifies. Remove the solidified fat and strain the gin through a cheesecloth. The resulting gin will have a subtle flavor and a silky texture.
* **Sous Vide Infusion:** Sous vide is a cooking technique where food is sealed in a bag and cooked in a water bath at a precise temperature. You can use sous vide to infuse gin with herbs, spices, or fruits. Simply combine the gin and your chosen ingredients in a sous vide bag, seal it, and cook it in a water bath at the desired temperature for a few hours. This technique allows for precise control over the infusion process, resulting in a more consistent and flavorful gin.
* **Barrel Aging:** As mentioned earlier, barrel-aged gin can add a unique depth and complexity to Lonkero. If you have access to a small oak barrel, you can age your own gin at home. Simply pour the gin into the barrel and let it age for a few weeks or months, depending on the desired flavor. Be sure to monitor the gin closely, as it can become over-oaked if aged for too long.
* **Homemade Grapefruit Syrup:** Instead of using grapefruit soda, you can make your own grapefruit syrup and combine it with carbonated water for a truly homemade Lonkero. To make grapefruit syrup, combine equal parts grapefruit juice and sugar in a saucepan and heat until the sugar is dissolved. Simmer for a few minutes until the syrup thickens slightly. Let it cool and store in the refrigerator. When making your Lonkero, combine the gin with the grapefruit syrup and top with carbonated water.

Lonkero Cocktails: Expanding the Possibilities

While the classic Lonkero is delicious on its own, it can also be used as a base for other cocktails. Here are a few Lonkero cocktail ideas:

* **Lonkero Spritz:** Combine Lonkero with Prosecco and a splash of Aperol for a refreshing and bubbly aperitivo.
* **Lonkero Mule:** Combine Lonkero with ginger beer and lime juice for a Finnish twist on the classic Moscow Mule.
* **Lonkero Collins:** Combine Lonkero with lemon juice, simple syrup, and carbonated water for a refreshing and tart Collins cocktail.
* **Lonkero Sour:** Combine Lonkero with lemon juice, simple syrup, and egg white (optional) for a creamy and tart Sour cocktail.
* **Lonkero Negroni:** Substitute Lonkero for the sweet vermouth in a classic Negroni for a drier and more refreshing take on the cocktail.
