Cold Smoker vs Hot Smoker – Which Should You Buy for Home Use?

If you're considering taking up home smoking, the first decision you'll face is whether to invest in a cold smoker or a hot smoker. It's not a matter of one being better than the other—they're fundamentally different tools that do different jobs. Understanding what each can achieve will help you pick the right one for what you actually want to cook.

What Is a Cold Smoker?

A cold smoker generates smoke at a very low temperature—typically between 15°C and 30°C. The smoke is cooled and separated from the heat source before it reaches your food, which means you can infuse strong, rich smoke flavour without cooking or significantly changing the texture of what's inside.

Cold smokers like ProQ cold smoke generators work by drawing smoke from a separate combustion chamber into the main smoking chamber. This creates a gentle, billowing atmosphere rather than the sharp heat of a traditional smoker. The process is slow and requires patience—smoking can take anywhere from 6 to 24 hours depending on what you're smoking and how much flavour you want.

The key advantage is that your ingredients remain in their original state. A salmon fillet stays moist and tender. Cheese doesn't sweat or lose its structure. You're adding smoke flavour without fundamentally cooking the food.

What Is a Hot Smoker?

A hot smoker, on the other hand, cooks your food whilst smoking it. Temperatures inside the chamber typically range from 65°C to 95°C, and they can reach higher temperatures if you want to achieve more aggressive cooking. The smoke comes directly from the heat source—whether that's a firebox or charcoal chamber—so smoke and heat are integrated.

Full hot smoker cabinets (vertical offset smokers, drum smokers, or cabinet-style units) are the traditional choice for home smoking. They're versatile, faster, and the finished product is already cooked. You get hot-smoked salmon, crispy bacon, pulled pork, and all the familiar results of outdoor smoking.

Key Differences and What You Can Actually Make

Salmon: Cold smoking is the traditional method. You'll get sliceable, delicate smoked salmon that keeps for weeks in the fridge and has the pale, silky texture of deli counter offerings. Hot smoking produces fully cooked, flaky salmon that's excellent warm or at room temperature but has a different texture entirely and a shorter shelf life.

Bacon: Cold-smoked bacon starts with cured pork belly that you smoke without cooking, then fry or bake yourself. You get all the smoke flavour with total control over how you finish it. Hot-smoked bacon is rare at home because the meat would shrink and lose quality. If you're keen on making bacon, a cold smoker is the only sensible choice.

Cheese: One of the best arguments for owning a cold smoker. Cheddar, mozzarella, and hard cheeses can be cold-smoked for hours without melting or changing texture, creating a genuinely distinctive product. Hot smoking simply doesn't work for cheese—it will melt or sweat.

Pulled Pork: This is where hot smokers excel. A brisket or pork shoulder needs low-and-slow cooking (12 to 16 hours at around 110°C), and that cooking happens in the smoker itself. You can't make proper pulled pork in a cold smoker because the collagen needs heat to break down into gelatin. You'll get smoky, raw meat—not the goal.

Cost, Space, and Practicality

Cold smoke generators are relatively affordable and compact. ProQ units sit in the £200–400 range and take up minimal space. You can even use them with an existing charcoal bbq as the smoke chamber, provided you can keep the main chamber cool (which often means smoking at night or in winter in the UK).

Hot smoker cabinets are a bigger investment. Decent barrel or cabinet smokers start around £400–600 and can climb to £2,000 or more for premium offset designs. They're heavier, require a permanent or semi-permanent spot in your garden, and need proper ventilation. But they're more self-contained and easier to use if you're new to smoking.

Skill and Attention Required

Cold smoking demands discipline. You need to maintain precise temperatures, monitor smoke generation, and be patient. It's a technique you learn. Most people find it rewarding once they grasp the basics.

Hot smoking is more forgiving. You manage a firebox or charcoal chamber, aim for a stable temperature zone, and let time do the work. Dial it in reasonably and you'll get good results even on your first attempt.

Which Should You Buy?

Buy a cold smoker if:

• You want smoked salmon, bacon, or cheese as your primary smoking goal
• You have limited garden space
• You're willing to be patient and learn a technique
• You want your smoked goods to last longer in storage

Buy a hot smoker if:

• You want pulled pork, brisket, ribs, and cooked smoked poultry
• You prefer results quickly
• You want the classic barbecue-smoking experience
• You're new to smoking and want a gentler learning curve

The Honest Take

Most home smokers end up wanting both eventually. A hot smoker becomes your weekend centrepiece for entertaining and slow-cooked meat. A cold smoker becomes your secret weapon for making shop-quality smoked salmon or cheese that genuinely impresses. But if you can only start with one, pick based on what you actually want to eat in the next year. Buy the tool that matches your ambition, not the one you think you should want.
