Energy drink: caffeine and marketing for a young audience

The growing success of energy drinks—beverages high in stimulant substances and increasingly popular among teenagers and even younger consumers—appears to be driven largely by marketing. On the one hand, there is an appealing promise for this target audience (more energy, more focus, better performance); on the other, the ability to embed themselves in familiar contexts and languages: sports, gaming, music, nightlife, studying. It is no coincidence that the European Parliament Research Service describes the global energy drink market as rapidly expanding and links its spread to consistent positioning around performance and attention.
This growth brings with it two consequences that are highly relevant for those working in the beverage industry. The first is technical: formulations and formats have become more varied, and production must sustain high volumes while maintaining very consistent sensory standards. The second is reputational and regulatory: public scrutiny—especially regarding consumption during adolescence—is high.

What are energy drinks and what are they made of?

Taking a closer look, energy drinks are far less mysterious than their pop-culture aura suggests. They are non-alcoholic beverages formulated to deliver a noticeable stimulating effect, and they do so by relying on an ingredient we have known for centuries: caffeine. Around it revolves a constellation of components that can vary from brand to brand, but always trace back to the same idea of easy energy: sugars or sweeteners, flavourings, B vitamins, sometimes taurine, and plant-based ingredients such as guaraná or maté.
The key figure for understanding the category is caffeine concentration. Many energy drinks sold in Europe sit at around 32 mg of caffeine per 100 ml—an amount that, in a standard 250 ml can, typically comes to about 80 mg of caffeine. This order of magnitude explains why consumers feel the “hit”, and it also explains why European rules require clear on-pack information above a certain threshold. In the European Union, for beverages other than tea and coffee with a caffeine content above 150 mg per litre, the label must carry the warning “High caffeine content. Not recommended for children and pregnant or breast-feeding women”, followed by the caffeine content expressed in mg per 100 ml, in the same field of vision as the name of the beverage.
Alongside caffeine, sugar is the other defining pillar, with two main variations. On one side are the classic formulations, where sugar contributes to taste, body, and overall palatability. On the other, the sugar-free or low-sugar segment has been growing for years, preserving the promise of stimulation through sweeteners and a drier, more restrained sensory profile. In its study on consumption among minors, the European Parliament also draws attention to the fact that many cans can contain significant amounts of sugar per serving—making the issue particularly sensitive when consumption becomes frequent or shifts towards younger age groups.
Then there is taurine, probably the best-known ingredient to the general public after caffeine. Taurine is a sulphur-containing organic compound, naturally present in many animal tissues, often described as an “atypical” amino acid because it is not incorporated into protein structures. In the body, it contributes to important physiological functions, including the formation of bile salts, the regulation of fluid balance in cells, and certain processes in the nervous and muscular systems. In energy drinks it is added as a functional ingredient, but it is not a stimulant like caffeine.

Market, marketing and target audiences: how a category’s success is built

The heart of the energy drink phenomenon lies not only in the formula, but in the staging, the context, the value system. In other words, the can works because it tells a story. For years, the category has built a coherent ecosystem made up of sponsorships, events, athletes, creators, and a visual language that evokes speed, challenge, endurance, and adrenaline.
The result is that, even when the overall market share remains relatively small compared to the wider universe of non-alcoholic beverages, the cultural impact is enormous. Producer organisations estimate that in the EU, energy drinks will still represent a niche in 2025, at roughly 1% to 2.5% of the soft drinks market. And yet, globally, the trajectory is that of an expanding category, with estimates placing the worldwide market at very high levels and projections still pointing to significant growth. This snapshot captures the product’s dual nature: it does not lead in volume, but it leads in visibility, premiumisation, and speed of innovation.
The target audience has changed, too—or rather, it has broadened. The “extreme” narrative still exists, but today it coexists with a more everyday kind of consumption linked to work shifts, driving, studying, recreational training, and urban life. To capture this variety, companies have multiplied their variants: sugar-free options, increasingly sophisticated flavours, limited editions, different formats, and even high-concentration versions such as energy shots—products with higher concentrations of caffeine and taurine per serving than traditional drinks.
Around this commercial drive, however, the issue of responsibility inevitably grows. Attention to minors is central: consumption among adolescents is high, and in Europe the political debate is increasingly geared towards discussing restrictions or limits on access, with different approaches across countries. In the meantime, the industry is also moving on the ground of self-regulation, as shown by the UNESDA code on promotion and labelling, which reiterates the European threshold of 150 mg/l and sets out a framework of voluntary marketing rules. This is an area where the line between reputation and regulation is thin: communication choices often anticipate, or seek to prevent, regulatory pressure.
