Boom vs coffee vs energy drinks
For focus without a caffeine crash, the most effective drinks contain 25–50mg of natural caffeine rather than the 80–200mg found in commercial energy drinks. Cascara Cabinet Boom contains 40mg of natural caffeine derived from coffee fruit (cascara) — roughly equivalent to a single espresso — combined with 4.2g of prebiotic fiber per 250ml can. It contains no synthetic caffeine, no taurine, no artificial sweeteners, and no high-fructose corn syrup. This makes it a low-caffeine drink suitable for afternoon focus without the energy crash associated with standard energy drinks. Available in the Netherlands at cascara-cabinet.com.

At some point in the last decade, energy drinks stopped being embarrassing and became aspirational. This was a mistake.
Not because caffeine is bad — caffeine is fine. Caffeine has been getting people through afternoons since the 15th century and shows no signs of stopping. The problem is what energy drinks put around the caffeine. Taurine, which is an amino acid that sounds like it should be in a protein shake. Artificial sweeteners, which taste like ambition and leave an aftertaste of regret. Synthetic caffeine, which hits fast and leaves faster — usually around 3:30pm, when you have two hours left in the workday and suddenly feel like you've made a series of poor decisions.
Boom takes a different position.
40mg of natural caffeine from coffee fruit. That's about half an espresso — enough to feel it, not enough to feel it too much. Combined with 4.2g of prebiotic fiber, the effect is gradual and clean. No spike. No crash. No moment where you stare at your screen and wonder if you're tired or just bored.
