## Questions & Answers

**Q: I don’t understand all this plunger stuff.  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

### ⭐⭐⭐⭐⭐ Great flavour with added bonus of big caffeine kick
*by A***R on 18 July 2018*

Best tasting coffee that I've ever had.I usually find coffees too bitter to be enjoyable, but thought I'd give Cannonball a try and I am so glad that I did. It has a really smooth, rich flavour without being bitter at all, love it. The big caffeine kick is definitely an added bonus and gets me moving in the morning.

### ⭐⭐⭐⭐ Very strong, tastes OK.
*by S***J on 27 October 2018*

A very strong coffee, I have a pretty decent Caffeine tolerance but one cup a day is definitely more then enough.I am rating it a 4 as a didn't feel the taste was all its cracked up to be according to their marketing campaign.

### ⭐⭐⭐⭐⭐ Strong and tastes great
*by M***S 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!
