Union Hand-Roasted Revelation Espresso Review

Union Hand-Roasted have been a benchmark for UK specialty coffee since before “specialty” was a common term here. Founded in East London in 2001, they were sourcing directly from farms and paying above-market prices a decade before it became fashionable. The Revelation is their flagship espresso blend, and it’s a stoater.

The Blend Profile

Revelation combines Colombian and Ethiopian beans, a classic pairing that balances structured sweetness (Colombia) with fruit complexity and florality (Ethiopia). Roasted to a medium development that sits lighter than most commercial espresso blends while remaining approachable for a range of extraction styles.

It’s a blend designed for specialty espresso drinkers who want complexity without the harshness of darker roasts.

Aroma

Out of the grinder: blood orange, dark berry, a hint of floral rose. This is not a chocolate-and-nuts espresso aroma. It’s more vivid and complex, closer to a fruit-forward filter coffee in character. That might sound challenging, but it’s genuinely appealing.

Pulling the Shot

This is where the Revelation rewards attention. It’s less forgiving than darker blends. Extraction parameters matter. At 93°C, 27 seconds, 1:2 ratio:

A beautiful espresso. The blood orange character is upfront and bright, the milk chocolate provides body and sweetness to balance, and there’s a dark berry (blackcurrant) note on the finish. The crema is persistent and orange-tinted, a classic indicator of good extraction on an Ethiopian-influenced blend.

Go slightly too short (under-extract): overly bright and acidic. Too long: the sweetness pushes into slightly bitter territory. There’s a narrower sweet spot here than with a dark blend, but once you’ve found it, it’s exceptional.

Temperature: 92–93°C works best. Higher temperatures exaggerate the acidity; lower mutes the complexity.

As a Milk Drink

Revelation is primarily designed as a straight espresso, but it handles milk surprisingly well. The blood orange character turns into a marmalade note in a flat white, more interesting than the typical chocolate-and-caramel result you’d get from a commercial blend. A properly made flat white with Revelation is a genuinely exciting drink.

Compared to Union’s Bright Note

The Revelation is a completely different beast from Union’s Bright Note Filter. Revelation rewards espresso technique; Bright Note is designed for filter and supermarket convenience. If you’re buying from Union specifically for espresso, Revelation is the one.

Value

£10.00 for 200g (£5.00/100g) is fair for this quality level. It’s available on Amazon UK for convenience and on Union’s website directly. Direct is preferable for freshness.

Who It’s Best For

• Experienced espresso drinkers comfortable dialling in parameters
• Anyone who finds standard espresso blends boring
• Flat white drinkers wanting something more interesting than typical café-style espresso
• People stepping up from beginner specialty coffee to something more nuanced

Not for: complete espresso beginners or those who want a set-and-forget blend. Look at Union’s Bright Note (for filter) or Rave Black Edition (forgiving espresso) instead.

Verdict

One of the best espresso blends available from a widely distributed UK roaster. The fruit complexity is genuine and the balance between orange character, chocolate body, and berry finish is expertly executed. It requires a bit more attention than a dark blend but rewards that attention generously.

Rating: 4.4/5
