Chewable Coffee Cubes: Caffeine in a Cube

If you’ve ever needed a quick caffeine hit but didn’t have time to brew—or just hate waiting in line at the coffee shop—you’re not alone. What if your caffeine could travel with you, require no mug, no water, and no wait? Enter chewable coffee cubes: solid, flavorful, and ready the moment you pop one in your mouth.

Each Go Cube delivers 50mg of caffeine—the equivalent of about half a standard cup of coffee—along with 10mg of vitamin B6 and 100mg of L-theanine, an amino acid found in green tea. That’s all in a vegan, gumdrop-textured cube with six grams of sugar and three flavor options: Pure Drip, Latte, and Mocha.

What Are Go Cubes?

Go Cubes are a shelf-stable, chewable coffee alternative designed to deliver both stimulation and focus. Unlike liquid coffee, these cubes combine caffeine with functional ingredients meant to support mental performance. Each piece has the texture of a fruit-flavored gumdrop and comes in three café-inspired flavors: Pure Drip (black coffee taste), Latte (milky note), and Mocha (chocolatey coffee blend).

The key ingredients per cube include:

• 50mg caffeine (about half a standard cup of brewed coffee)
• 10mg Vitamin B6 (supports cognitive function)
• 100mg L-theanine (found naturally in green tea, helps balance caffeine jitters)
• ~6g sugar (per cube)

How Go Cubes Work

Go Cubes were created to offer a faster, more convenient caffeine experience without sacrificing the functional benefits of well-rounded stimulation. The inclusion of L-theanine alongside caffeine is a common tactic in nootropics: L-theanine helps mitigate the anxiety or crash that can come with straight caffeine, leading to a smoother, more focused energy boost.

Vitamin B6 contributes to neurotransmitter function, further aiding mental clarity. Together with the moderate caffeine dose, the formula is aimed at improving both alertness and memory performance—without requiring a coffee maker, a barista, or even a straw.

The Business Behind the Cube

Go Cubes were developed by Brandt and Woo, who launched the product through a crowdfunding campaign that raised nearly $40,000. The international launch offers the cubes in packs of four, with six packs available for $20.70. That breaks down to roughly $1.73 per serving—or about what you’d pay for a basic cup of drip coffee, and significantly less than most café prices.

Each four-cube pack offers the equivalent of about two cups of coffee, depending on how you chew. At $20.70 for six packs (24 cubes total), the per-unit cost stays low for frequent users seeking a grab-and-go stimulant.

Flavors and Texture

The cubes mimic the experience of chewing a sweet, slightly tangy gumdrop—but with functional purpose. The three available flavors are designed to reflect familiar coffee experiences:

• Pure Drip: A straightforward black coffee taste
• Latte: A smoother, milky-style flavor
• Mocha: A chocolate-coffee combination

With a soft, chewable texture similar to candy, they dissolve steadily in the mouth and deliver caffeine and active compounds through both saliva absorption and ingestion.
