Cast Iron Coffee Roasters coffee review

What Cast Iron Coffee Roasters sells, what it costs against the rest of the market, and who should buy it.

Updated 3 September 2026Written by the We Try Coffee team

Cast Iron Coffee Roasters sells 13 coffees in the UK and the cheapest comes out at 59p a cup, which is less than most of the whole bean coffee we track. Cheap coffee is easy to find and hard to trust, so the useful question is not whether it is cheap. It is what the range actually contains, and whether the bag doing the heavy lifting is the one you would want.

Short answer

Delicate and fruit-forward rather than strong, for below the going rate.

Cheaper than 61% of the whole bean coffee we track

What kind of roaster this is

Cast Iron Coffee Roasters sells whole bean in the UK, and we track 13 of their coffees, in 1kg and 340g.

Expect blends here rather than named farms: 100% of the classified range is blended. The trade is a familiar one. You give up the story on the label and you get a cup that does not drift between orders. The buying reaches 7 countries across the range, which is a wide book for a brand this size. The roasting spans 3 of our five levels, so there is a genuine choice to make inside the range rather than one house style applied to everything. Bags come in both small and kilo sizes, and the gap between them per kilo is usually the largest saving available anywhere on this page.

What Cast Iron Coffee Roasters coffee costs

The range runs from 59p to £2.25 a cup across 13 products. That is a 3.8× spread inside a single brand, which is why "is Cast Iron Coffee Roasters expensive" is the wrong question; the right one is which bag you pick. The cheapest is Unity in the 1kg, and the dearest is Andy Llanos in the 1kg.

Bags themselves run £15.00 to £125.00. Ignore that column. A bigger bag costs more and almost always costs less per cup, which is the only number that follows you home.

The one to buy

If you buy one thing from Cast Iron Coffee Roasters, buy Unity. At 59p a cup it comes in around 7% under the median for whole bean coffee, and that is measured against every brand in our catalogue rather than against Cast Iron Coffee Roasters's own list prices. Nothing else in the range gets close on that test.

What that costs over a year

How much coffee do you drink?
  • Cast Iron Coffee Roasters£0.58 per cup£427
  • Typical whole bean£0.63 per cup, our median£460

At 2 cups a day, Cast Iron Coffee Roasters costs £33 less a year than the typical whole bean coffee we track. That is the same coffee habit, bought better.

How Cast Iron Coffee Roasters tastes

We have not tasted Cast Iron Coffee Roasters, so we are not going to invent a tasting note. A flavour score we did not earn would be worth less than none, and this section would be the easiest place on the site to quietly make one up. What we can show you is measured: where every coffee in the range sits on our own five-point roast scale, and which origins go into it. Roast is the strongest single predictor of whether a cup arrives bright and fruity or dark and chocolatey, so it is the closest honest answer to what this brand is like to drink.

How Cast Iron Coffee Roasters roasts

Every coffee standardised onto our own five-point scale rather than the roaster's. Read these as tendencies: origin, process and how you brew all move the cup.

Who it suits

  • People who found something they like and want it to taste the same next year, which is what a blend is for.
  • Anyone whose real comparison is supermarket own-brand, judged per cup rather than by the label.
  • People who want to choose their own roast rather than take the roaster's word for it, since the range covers 3 of our five levels.

Is it good value?

Our test is simple, and it is the same one we apply to everything: cost per cup against the median for the same format. Cast Iron Coffee Roasters lands around the middle. It is not the cheapest way to a cup of coffee, and the money above the median buys convenience and consistency rather than a smaller bill. Whether that is a fair trade is genuinely your call, not ours.
