Can you use this like a normal coffee in the morning? A few spoons into a mug, pour water in and drink??** A: Hi, this is ground whole bean coffee rather than instant coffee so it needs to be brewed and filtered. This coffee will not dissolve in water. What you are describing is Instant Coffee. This is where someone has already brewed the coffee, evaporated the water and put the left over granules in a jar. If brewing coffee is too time consuming, you might be interested in the single-serve bags we are bringing out later in the year. **Q: Whch one of these is the coarse grind? As labelled differently to website** A: Hi Shaun. This is a medium grind, suitable for most coffee makers. Unfortunately we aren't able to offer the same variety of grind types here. **Q: How suitable is this for cold brew?** A: Works fine as cold brew, considering how strong the coffee is its pretty smooth. Will be even smoother as a cold brew, good luck though as it will be a lot of caffeine 😉 **Q: On your website i can choose between fine, medium and coarse grinds but here it's only beans or ground. if i buy ground from here, which one do i get?** A: This coffee is a medium grind and is suitable for most coffee makers. But for best results we would advise against using this grind type in a good quality espresso machine as it will be slightly too coarse. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Strong and tastes great *by M***S on Reviewed in the United Kingdom on 10 September 2020* I ordered this as a last minute thing as I ran out of my usual ground coffee. It arrived next day delivery (09/09/20) and I had my first cup this morning (10/09/20).I can safely say I will be making this my new usual. The taste was a lot more subtle and smooth than what I'd bought before and the kick it gave me as my morning get up and go lasted right through till midday.A company and coffee I would recommend to everyone! ### ⭐⭐⭐⭐ 4.0 out of 5 stars Activates your bowels and gives you energy, taste is so and so. *by L***U on Reviewed in the United Kingdom on 6 July 2020* Taste: Opposite of Arabica. Not bitter, more towards an Alkaline flavor if it's lightly filtered. If you have a strong filter, the taste is almost non existent which can be a good thing.Jitters: Have not experienced them yet and i've had up to 2 strongly brewed cups.Energy: Regardless of brewing method, this coffee does wake me up. And i'm one of those people who is chronically tired. This coffee does it for me.Bowels: This coffee consistently and abnormally activated my bowels several times a day the first week i had it. On the second week it activate my bowels ~ once a day, 2 times max. Very nice cleansing effect.-If brewed incorrectly, will have almost no taste. It will still give you a normal level of energy. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Strong, good quality and easy to drink! *by L***N on Reviewed in the United Kingdom on 16 April 2020* Really enjoyed this coffee. It’s strong and has a good flavour. not bitter or acidic at all. I’m a coffee and caffeine but but I find a couple of cups of this keeps me rocking for a full day. Taste could be just a wee bit more complex but really no complaints... will likely buy again. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/70454142-maximum-charge-super-strong-coffee-from-robusta-beans-medium-roast](https://www.desertcart.co.uk/products/70454142-maximum-charge-super-strong-coffee-from-robusta-beans-medium-roast) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-20*
