ProQ Cold Smoke Generator Review UK – Is It Worth Buying?

Cold smoking transforms meat, fish, and cheese without cooking them. The ProQ Cold Smoke Generator is one of the few devices that makes this accessible to home smokers without building a separate cold-smoke cabinet. If you're serious about expanding beyond hot smoking, it's worth understanding what it does—and what it doesn't.

What Is the ProQ Cold Smoke Generator?

The ProQ is a small drum filled with compressed wood dust. When lit, the dust smoulders slowly, producing dense, cool smoke. You attach it to your existing smoker via a tube, and the smoke drifts through your food without raising internal temperature. In theory, this means salmon, mackerel, and cheese stay raw while absorbing deep smoke flavour.

It's a passive system—no electricity, no temperature control. That simplicity is both its strength and its limitation.

How Setup Works

Installation is straightforward. The generator sits on the ground or a shelf below your smoker. A flexible steel tube (supplied) connects the outlet to your smoker's inlet, or you place it inside the smoking chamber. You fill the drum with wood dust, use the supplied firelighter to ignite the fuel, and let it smoulder for 30–60 minutes depending on the dust density and ambient temperature.

In summer, it works reliably. In autumn and winter, colder air slows the smoulder, sometimes extinguishing it entirely. You'll learn to shield it from wind or pre-warm the drum. It's fiddly, but not dealbreaker-level.

The cleaning is minimal—just empty ash when finished. The drum itself lasts years if you don't subject it to direct rain storage.

Wood Dust Quality Matters

Not all wood dust is equal. The standard Hickory and Apple dusts work, but many users find them produces inconsistent burns and clogging. Better results come from dedicated cold-smoke dust: brands like Bradley Smoker pucks (which you can break into dust) or sourcing premium hardwood dust from specialist smoke-supply shops.

Expect to experiment. Oak dust is reliable and produces less acrid smoke than some cheaper blends. Beech is mild. Avoid treated sawdust or softwoods—they taste sharp and can impart unwanted flavours.

What We Actually Tested

Over several months, the realistic outcomes were:

Fish: Atlantic salmon and mackerel smoked beautifully. The flesh stayed delicate, took colour quickly, and developed genuine smoke flavour by hour two. Not as thick as hot-smoked versions, but more subtle and truer to the ingredient.

Cheese: Cheddar and mature Gouda worked well. Soft cheeses like brie sweated and oozed, so hard cheeses only.

Meat: Bacon smoked cold is technically safe if finished properly, but it requires knowledge of cure depths and equilibrium curing. For home use, most people stick to pre-cured meats like ham.

Vegetables: Paprika, salt flakes, and even nuts took smoke cleanly, though the food needs to be dry beforehand.

Temperature control was the real constraint. In May through September, you could reliably keep your chamber below 25°C. Winter and early spring required ice packs or running early morning.

Real Strengths

The ProQ is cheap compared to building a separate cold-smoke chamber. It integrates with kit you already own. There's no electronics to fail. If you have a large drum smoker with controllable airflow, you can dial in fine, cool smoke delivery. And for occasional use—smoking a side of salmon for a dinner party—it's efficient and produces excellent results.

The learning curve is shallow. After two runs, most people understand the variables.

Genuine Limitations

The smoulder rate is weather-dependent. High humidity or cold winds can kill the burn. There's no thermostat, so you're managing temperature with ice and airflow control—doable, but not automatic. The drum takes up space, and the tube is an eyesore if permanence matters. And for large batches, it's slow: each 30–60 minute smoulder cycle yields moderate smoke, not the dense, rapid coating you get from a professional box.

Consistency is harder than hot smoking. Two identical runs can produce different results based on humidity, dust batch, and ambient temperature.

How It Compares to Alternatives

A cheap Bradley Smoker (American import) offers better temperature control and consistency but uses proprietary pucks and is less elegant in a UK garden. Building a separate insulated chamber gives you absolute control but costs £200–500 and requires carpentry.

The Smoking Gun (handheld, propane-powered) is portable but generates heat and gives very short smoke bursts—better for finishing a dish than batch-smoking. The ProQ wins on cost, simplicity, and total smoke volume per session.

For home use, the ProQ sits in the middle: cheaper and easier than a cabinet, more substantial than a gun, more consistent than improvised setups.

Verdict

The ProQ Cold Smoke Generator is worth buying if you already own a drum smoker, want to cold-smoke occasionally (2–4 times a month), and accept that results depend partly on weather and willingness to troubleshoot. It's not suitable if you need consistent, high-volume cold smoking or live in a very windy, damp climate where the smoulder won't stay lit.

For the £40–60 investment, it's one of the few legitimate routes into cold smoking without major outlay. Treat it as a learning tool first—understand the technique, find your preferred wood dust, dial in your temperature management. By month three, you'll know if it fits your smoking style or if a larger investment makes sense.
