Decaf Ground Coffee · Medium Roast · 340g Bag

Bulletproof® Decaffeinated Coffee (Ground) — 340g

A medium roast Arabica ground coffee with most of the caffeine removed. Same estate-sourced beans as the Original Bulletproof Coffee, decaffeinated using a water-based process that preserves the flavour profile.

340g bag · Hand-picked beans · Rainforest Alliance Certified · Nitrogen-flushed packaging with degassing valve for freshness.

Key Points

  • Decaffeinated coffee — the same beans as the Original Bulletproof Coffee, decaffeinated using a water-based process
  • Single-origin coffee — sourced from high-altitude estates in Guatemala (June–December roasting) and Colombia (December–June roasting)
  • Hand-picked beans — only ripe berries selected by skilled harvesters
  • Medium roast — retains the tasting profile of the original bean stock
  • Rainforest Alliance Certified beans from estate farms
  • Pre-ground to a medium grind — suited to drip, syphon, and pour-over brewing methods

What It Is

This is the Bulletproof Decaffeinated Coffee in pre-ground format. It uses the same estate-sourced Arabica beans as the Original Bulletproof Coffee, decaffeinated to remove most of the caffeine while preserving the flavour profile as much as possible.

No added vitamins, no added mushroom extracts, no added Coffeeberry® or other ingredients. The bag contains coffee.

This is the after-2pm coffee — suited to those who want to enjoy a hot coffee later in the day without disrupting sleep, or as a general option for those who limit caffeine intake. If you prefer to grind your own beans, the same coffee is also available in whole bean 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.

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 roasting.

How the beans are decaffeinated: Beans are decaffeinated using a water-based process that removes most of the caffeine while preserving the flavour profile.

Brewing Notes

The medium grind in this product is set up for:

  • Drip coffee makers — ideal grind
  • Syphon brewing — ideal grind
  • Pour over — works well
  • Moka pots — works well

For AeroPress, French press, cold brew, or Turkish coffee, the medium grind isn’t ideal — you’ll need to increase the brew time (typically 3+ minutes) to compensate. If you regularly use these methods, the whole-bean version may suit you better. Decaf coffee brews the same way as regular coffee — no adjustment needed for the decaffeination process.

The Bulletproof Coffee Recipe

"Bulletproof Coffee" is a popular preparation method that combines brewed coffee with grass-fed butter (or ghee) and MCT oil. The decaf version works exactly the same way, just without the caffeine hit — making it suited to afternoon or evening use if you still want the fat-fuelled drink but not the stimulant.

Bulletproof Coffee Preparation

  1. Brew 2 cups of coffee using the method of your choice
  2. Combine with 2 tablespoons of unsalted grass-fed butter (or grass-fed ghee for a dairy-free option)
  3. Add 2 tablespoons of MCT oil (such as Primal Warrior C8 MCT Oil or Bulletproof Brain Octane)
  4. Blend in a high-speed blender (or use an Aerolatte® frother) until a creamy head of foam forms
  5. Pour and drink while hot

The fats give the drink a creamy texture and a higher caloric content than plain coffee. Treat it as a meal rather than a beverage if using it as a breakfast replacement.

Packaging Notes

Pre-ground coffee tends to lose freshness faster than whole beans because the increased surface area accelerates oxidation. To extend freshness, 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

Is decaf really caffeine-free?

Decaf coffee is not completely caffeine-free. Standard decaffeination removes approximately 97–99% of the caffeine, leaving a small amount — typically around 2–5mg per cup, compared with 80–120mg in a regular cup. This is a small enough amount that most people find it doesn’t affect sleep or trigger caffeine sensitivity.

Does decaf taste different from regular coffee?

Water-based decaffeination processes preserve most of the flavour compounds, so quality decaf can taste very close to the equivalent regular coffee. Using the same estate-sourced beans as the Original Bulletproof Coffee, this decaf keeps a similar tasting profile with only subtle differences.

Why ground vs whole bean?

Whole beans stay fresher longer because the bean keeps the volatile aromatics inside until you grind. Pre-ground coffee is more convenient — no grinder needed, less noise. The trade-off is freshness vs convenience. If you have a grinder, whole beans give the freshest cup. If not, the ground version works.

Do I have to make Bulletproof Coffee with it?

No. This is regular decaf ground coffee. Make it however you normally make coffee. The Bulletproof Coffee recipe (with butter and MCT oil) is one popular option but not the only way to use it.

Zero regrets

Buying decaf usually feels like admitting defeat, but man up. Totally enjoyed it in the end. Just good decafe. It tastes like an honest, heavy roast, scratches the coffee itch completely, and lets you wind down without staring at the ceiling. Genuinely good brew.
