## Description

Lean Caffeine High Caffeine Coffee Beans – World’s Strongest Coffee – Mycotoxin & Heavy Metal Free – Whole Bean Coffee High Caffeine - UK Clean & Low Acid Dark Roast Strong Coffee - 908g (1 Pack) : desertcart.co.uk: Grocery

Review: Great Espresso with satisfaction of no chemicals - Great taste. Makes an extremely good espresso, rich but not bitter. ( I use a sage barista machine) …. No complaints from the americano drinkers either. Love that it’s mycotoxin & chemical free (obviously can’t test this theory ) but I seem to have less sluggish reaction to this … I’m a repeat buyer 👍🏼
Review: Clean caffeine with no adverse side effects - Beautiful tasting coffee. As long as your grinder is dialled in correctly you'll get a really smooth, quality shot with crema. With the toxins removed there are no headaches or similar that you get from regular beans. Furthermore - extra caffeine means extra alert and I don't use any other beans now. Personally I feel it's great value for money and no matter how you take your coffee you will not be disappointed with this exceptional bean

## Questions & Answers

**Q: Can you put these beans in a perculator or  do thet need to be crushed beforehand?**
A: Hello. Yes they would need to be ground before hand then follow the percolator instructions. Thanks.

**Q: What mg is this coffee per cup?**
A: Hi. It’s 2.35g of caffeine per 100g. So depending on how strong you make your coffee will determine the grams of caffeine per cup. Normal range is 10-13g of coffee beans per coffee. If we take 10g it would be 0.235g of caffeine per cup. 
It’s super strong. I can only have one single espresso of this a day. It’s like those espressos you get in Italy!
Hope this helps. 
Jamie

**Q: Can I use this in a percolator?**
A: Some of my customers have used with great success in one of those Moka pots (stove top percolator):

1.5 tablespoons packed tight
200ml of water

Let it boil through to the top, but remove from the stove before its starts gurgling and sputtering the remnants of any remaining coffee… you don’t really want that stuff mixed with your drink.

I then fill a mug with what was boiled and top off the cup with another 100ml of boiling water or so

**Q: Are all of your coffee beans Dark roast? I would like to buy some but require light - medium roast.**
A: We do a medium roast for our Decaf coffee. But all our caffeinated are darker roast
