Caffeine System

80 mg

Total caffeine – one espresso equivalent in 250ml

32 mg/100ml

Concentration – Within the regulatory limits of soft drinks.

45 min

Peak plasma concentration after ingestion

5 hr

Half-life – crash arrives at hour 10

First contact : Carbonation accelerates gastric absorption. Citric acid drops gastric pH, increasing caffeine solubility before it reaches the small intestine — delivering faster onset than capsule caffeine.
10 min : Caffeine enters the bloodstream. Heart rate rises slightly. Adenosine receptors begin to block — drowsiness signaling suppressed at the synaptic level.
30 min : Taurine crosses the blood-brain barrier alongside caffeine. Norepinephrine and dopamine release increases. B-vitamins now bioavailable for ATP synthesis cofactor roles.
45 min : peak. Full caffeine plasma concentration. Adenosine fully blocked, liver enzyme activity elevated, working memory and reaction time at maximum benefit window.
5–6 hour half-life : Caffeine concentration halved. Adenosine receptors recovering — rebound fatigue begins as adenosine catches up to blocked receptors. The crash is physiologically inevitable.

Carbonation Balance

3.7 vol

The absorption rate is accelerated by the midpoint between sparkling water (2.5) and cola (4.2).

3.1 pH

Sharp acidity is facilitated by citric acid. Enhances carbonation and conceals excessive richness.

4.7bar

Pressurised at a temperature of 4 C. To optimise sensory anticipation prior to the initial intake, the opening pressure is specifically calibrated.

2.8 g/L

Sugar (or sweetener system) has a strong impact on the perception of carbonation. High sweetness can mask the sharpness..

Flavor Engineering

Taurine Synergy

1000mg taurine softens caffeine’s bitter edge via slight salinity. Its neuromodulatory effect contributes to the drink’s taste profile.

Sucrose + Glucose Split

27g total in a near 1:1 ratio. Sucrose provides body and sustained sweetness, glucose delivers an immediate onset, avoiding a cloying finish.

B-Vitamin Top Note

Niacin, B6, and B12 contribute a faint yeasty-umami note associated with a functional profile.

Citric Acid Arc

Peaks sharply at 2 seconds, decays by 4s. This sensory arc associates citric onset with alertness as a learned stimulus-response loop.
