- Hand-picked beans — only ripe berries selected by skilled harvesters
- Medium-dark roast — full-bodied and smooth, with tasting notes of cherry, almond, and caramel
- Rainforest Alliance Certified beans from estate farms
- Sustainable processing — washed and mechanically dried via established techniques
- Whole bean format — grind fresh at home for optimal flavour and full control over grind size
What It Is
This is The Mentalist in whole bean format — Bulletproof®'s medium-dark roast option. It uses the same estate-sourced Arabica beans as the Original Bulletproof Coffee, taken to a longer roast for a fuller body and darker flavour profile. No added ingredients — just coffee.
The medium-dark roast sits between the Original (medium) and French Kick (dark) — if you prefer a bolder coffee than the Original but not as intense as the darker French Kick, The Mentalist is the middle option.
If you prefer ready-to-brew convenience, the same coffee is also available in pre-ground format.
Sourcing
Where the beans come from: Bulletproof sources beans from estate farms in Guatemala and Colombia on a six-month rotation — beans roasted between June and December come from a Guatemalan estate; beans roasted between December and June come from a Colombian estate. This pattern applies across all Bulletproof coffee roasts.
How the beans are picked: Hand-picked by experienced coffee harvesters who select only perfectly ripe berries.
How the beans are processed: Beans are sustainably washed and mechanically dried before being roasted to a medium-dark profile.

Brewing Notes
Whole beans give you full control over grind size:
- Espresso — fine grind (the medium-dark roast suits espresso especially well)
- Moka pot / AeroPress — fine-to-medium grind
- Drip / pour-over / syphon — medium grind
- French press — coarse grind, 4-minute steep
- Cold brew — coarse grind, 12–24 hour steep
The medium-dark roast profile works particularly well in espresso and moka pot brewing where the fuller body carries through milk. Grind just before brewing for the freshest flavour.
The Bulletproof Coffee Recipe
"Bulletproof Coffee" is a popular preparation method that combines brewed coffee with grass-fed butter (or ghee) and MCT oil. It originated as a high-fat breakfast option for people on ketogenic or low-carb dietary patterns who want to skip a traditional carbohydrate-based breakfast.
Bulletproof Coffee Preparation
- Grind 2 cups worth of beans (medium grind for drip, fine for espresso)
- Brew 2 cups of coffee using the method of your choice
- Combine with 2 tablespoons of unsalted grass-fed butter (or grass-fed ghee for a dairy-free option)
- Add 2 tablespoons of MCT oil (such as Primal Warrior C8 MCT Oil or Bulletproof Brain Octane)
- Blend in a high-speed blender (or use an Aerolatte® frother) until a creamy head of foam forms
- Pour and drink while hot
The medium-dark roast profile of The Mentalist gives Bulletproof Coffee a fuller, richer body compared with the Original.
Packaging Notes
Whole beans stay fresher for longer than pre-ground coffee because the intact bean protects volatile aromatic compounds from oxidation. To extend freshness further, this product is packaged in a nitrogen-flushed bag with a one-way degassing valve — the nitrogen displaces oxygen at packaging, and the valve lets CO2 from the beans escape without letting oxygen in. Bags stay fresh at room temperature for several weeks once received. For longer storage, unopened bags can be frozen (place tape over the degassing valve first to prevent moisture infiltration).
Good to Know
How is this different from the Original Bulletproof Coffee?
Same estate-sourced beans and processing, but roasted longer to reach a medium-dark profile. The result is a fuller-bodied cup with darker flavour notes (cherry, almond, caramel) instead of the Original’s brighter fruit-and-spice profile (cinnamon, plum, orange).
Which roast should I pick?
If you like a smooth, balanced cup with brighter notes, go with the Original (medium roast). If you like a fuller-bodied cup that carries through milk-based drinks, The Mentalist (this product) is a good pick. If you want something darker and more intense, try French Kick (dark roast). If you want to try all three, the 3-Roast Variety Pack has one bag of each.
How much caffeine is in a cup?
Coffee caffeine varies with brewing method and water-to-coffee ratio. A typical cup of brewed drip coffee (240mL) made from this coffee contains roughly 80–120mg of caffeine. Australian dietary guidelines recommend adults limit caffeine intake to no more than 400mg per day from all sources combined.
Do I have to make Bulletproof Coffee with it?
No. These are regular coffee beans. Make coffee however you normally do — espresso, drip, French press, or however you like. The Bulletproof Coffee recipe (with butter and MCT oil) is one popular option but not the only way to use it.
