Quantum Coffee Roasters coffee review

What Quantum 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

Quantum Coffee Roasters asks 72p a cup at its cheapest, which is more than most ground coffee we list. Plenty of brands charge that and are worth it. The question is what you get for the difference, so here is the range, what it costs against everything else, and where we would put the money.

Short answer

A middle-of-the-road medium roast, black or white, at the going rate.

Cheaper than 48% of the ground coffee we track

What kind of roaster this is

Quantum Coffee Roasters sells whole bean and ground in the UK, and we track 37 of their coffees, in 900g, 250g, 225g and 125g.

89% of the Quantum Coffee Roasters range we can classify is blended. Blending has a bad name it does not deserve; it is how a roaster keeps a coffee tasting like itself when the harvest behind it changes, and it is the reason your regular bag is still your regular bag in January. The buying reaches 20 countries across the range, which is a wide book for a brand this size. The roasting spans 4 of our five levels, so there is a genuine choice to make inside the range rather than one house style applied to everything. Nothing here comes in a kilo bag. That keeps the coffee fresher in your cupboard and costs you the bulk discount, which is the trade you are making whether or not anyone points it out.

What Quantum Coffee Roasters coffee costs

The range runs from 70p to £2.88 a cup across 37 products. That is a 4.1× spread inside a single brand, which is why "is Quantum Coffee Roasters expensive" is the wrong question; the right one is which bag you pick. The cheapest is Brazil in the 900g, and the dearest is Yemen in the 125g.

Bags themselves run £10.00 to £64.00. 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

Brazil is the cheapest thing Quantum Coffee Roasters sells, at 70p a cup. We cannot yet set that against a market average for whole bean coffee, so treat it as the floor of the range rather than a verdict on value.

What that costs over a year

How much coffee do you drink?
  • Quantum Coffee Roasters£0.72 per cup£526
  • Typical ground£0.71 per cup, our median£516

At 2 cups a day, Quantum Coffee Roasters costs £10 more a year than the typical ground coffee we track. Worth knowing before you commit to a subscription.

How Quantum Coffee Roasters tastes

We have not tasted Quantum 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 Quantum 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.
  • Slow drinkers, and anyone who would rather buy little and often than watch a kilo go stale.
  • People who want to choose their own roast rather than take the roaster's word for it, since the range covers 4 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. Quantum 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.
