Lemonade is a carbonated soft drink based on water, sugar and flavourings. The term derives from the French limonade, which in turn goes back to the Italian limonata – both originally referred to lemon water. Today, lemonade refers to an entire category of soft drinks characterised by sweetness, acidity and carbonation.
What defines lemonade
Classic lemonade consists of four basic components: water, sugar or sweetener, acid (usually citric acid) and carbonation. Flavourings are added to determine the character, ranging from lemon and orange to artificial flavour profiles. In Germany, the Fruit Juice Ordinance stipulates that lemonade sold with a fruit designation must contain a certain minimum fruit content. Lemonade must contain at least three percent lemon juice, while orangeade requires at least four percent.
The sugar content typically ranges from eight to twelve percent, which equates to about 80 to 120 grams per litre. This is significantly higher than in most fruit juices. The carbonation provides the tingling mouthfeel and enhances the flavours. Without carbonation, it is not considered lemonade but syrup or juice.
Homemade vs. industrial lemonade
Behind the bar, we differentiate between industrially produced lemonade from a bottle and homemade lemonade. Homemade versions are usually based on fresh citrus or fruit juice, simple syrup and soda water. They taste fresher, less sweet and allow precise flavour control. The effort is manageable: juice the fruit, mix with syrup, top up with soda.
Industrial lemonades rely on concentrates, flavourings and often colourants. They are shelf-stable, consistent in taste and cost-effective to procure. In the bar, we mainly use them as fillers in highballs or when guests request a specific brand. For high-quality drinks, many bars now opt for house-made lemonades or premium products from small producers that use real ingredients.
Lemonade at the bar
In practice, lemonade serves two roles: as a standalone drink and as an ingredient. As a filler, it extends spirits in highballs and long drinks – gin with lemonade, rum with cola (which is technically also a lemonade), vodka with orangeade. It contributes sweetness, carbonation and aroma, making drinks more approachable.
Some classic cocktails use lemonade as a component. The Tom Collins, for example, is essentially a Gin Sour topped up with soda water to become a lemonade. If you substitute commercial lemonade for the soda, you end up with a different drink – sweeter and less balanced. This distinction is important: soda water is neutral, lemonade is sweetened and flavoured.
With homemade lemonades, we can incorporate herbs, spices or unusual fruits. Ginger lemonade, rhubarb lemonade or cucumber lemonade are examples that work as non-alcoholic options or mixers for creative drinks. The advantage: full control over sweetness and acidity.
Common misconceptions
Many confuse lemonade with soft drink – not entirely wrong, but imprecise. Soft drink is the umbrella term for all non-alcoholic refreshments, while lemonade is a subcategory. Cola, Tonic Water and Ginger Ale are technically lemonades, but are usually treated separately.
Another misconception: lemonade is always artificial. This holds true for many supermarket products, but not all. There are high-quality lemonades made with real juice and without flavourings. Conversely, homemade does not automatically mean healthier – even house-made lemonade contains a lot of sugar.
Some believe lemonade must always be yellow. This stems from the lemon reference in the name, but lemonade comes in all colours and flavours. Raspberry lemonade is red, woodruff lemonade is green. The colour says nothing about quality; often, it comes from colourants.

Frequently asked questions
Can I replace lemonade with soda water?
No, not directly. Soda water is neutral and unsweetened; lemonade brings sugar and flavour. If you substitute soda for lemonade, you’ll need to add sweetness and flavour separately to maintain balance.
How long does homemade lemonade keep?
In the refrigerator, about three to four days if made with fresh juice. Without preservatives, it begins to oxidise and loses freshness. It’s best to prepare only the amount you need in the near term.
Is Tonic Water a lemonade?
Technically yes, practically it’s treated separately. Tonic Water contains quinine, giving it a bitter taste, and is almost exclusively used as a mixer. In drink theory, it belongs to the lemonade family, but in the bar it has its own category.
Why does draught lemonade taste different?
Because it is mixed directly at the tap from syrup and soda water. The mixing ratio can vary, the carbonation is often stronger and the temperature colder. The result is technically lemonade, but tastes different from bottled lemonade.
