20 Homemade Cold Smoker DIY Ideas Easy to Take On!

Cold smoking certainly seems a lot more alluring than hot smoking. Now I’m not trying to bad-mouth DIY hot smokers and the whole concept of hot smoking. Personally, I simply can’t enough of the hot, smoky essence of actual cooked meat. But then the flavors that cold smoking and only cold smoking infuse into food are just so heavenly.

The effort required for building a homemade cold smoker is a lot more complicated, no doubt about that. You have to fill a certain amount of space with enough smoke for a certain amount of hours. And the temperature during this time should be just right; the goal is to prevent the food from cooking and, at the same time, from spoiling as well.

But all this will only happen once you know how to build a cold smoker. So before I get into all the DIY cold smoker plans, let’s first get to know a little bit more about cold smoking.

Hot Smoking and Cold Smoking – What’s the Difference?

With cold smoking, flavors are infused into the food through the smoke. But with hot smoking, flavors are infused while the food is getting cooked.

But then it’s important for the temperature to be low and well-controlled if you want to cold smoke the right way. What cold smoking does is it preserves the food since smoke dries up moisture and activates bacteria-fighting properties. But for this to happen, 48 hours of cold smoking is necessary. After which, no refrigerator storage is required.

Hot smoking, on the other hand, cooks your food at a higher temperature. If what you really desire is a delicious smoky flavor, then hot smoking is better. Plus, it also leaves your meats with more juice and a more tender texture/taste.

What All Can Be Cold Smoked?

Firstly, if you’ve never cold smoked anything before, then it’s best to start small. Such as cold smoking cheese instead of choosing big items like salmon or salami. Cheese is certainly less of a risk than salmon or salami.

Just grow accustomed to the whole cold smoking technique first, keeping in mind safety risks of course. And once you’re confident enough to take on more, here’s a list of all the foods you can cold smoke…

Vegetables, nuts, tofu, hardboiled eggs, garlic, and olive oil.

The most popular ones being fish (smoked salmon) and sausage. But then these are high-risk options because of the chances of foodborne botulism if they’re not properly handled.

Cold Smoking Cheese

Since foodborne botulism feels like a buzz-kill, how about then just cold-smoking cheese?

In about 2 to 4 hours only you have delicious, cold-smoked cheese without any serious health risks lurking over your indulgences. But then there is that chance of cheese melting during the smoking process if the temperature becomes too hot. Below 90 degrees Fahrenheit is perfect for cold smoking and the cheese to remain solid.

The warmer the weather conditions, the lower the temperature in your cold smoker.

So for cold smoking cheese in warmer climates, make sure you do that in the evening or morning. Select a particular time when the surrounding temperature is cooler. Or you could just add ice into the smoking compartment/chamber, so the air around the cheese is cooled.

Another useful tip – cut the cheese into small chunks for the smoky flavor to penetrate deeper beyond just the surface of the cheese. Keep turning those chunks to get an evenly distributed smoky flavor.

Many cold-smoking enthusiasts prefer using cheese at room temperature as it prevents condensation during the process. Once done, wrap up the cheese (using plastic wrap) and then store it in the refrigerator if you want the flavor to get intensified.

Safety Tips for Cold Smoking

Here are some quick safety tips to make your cold smoking experience successful in every way…

  • Follow only expert recipes, and not what your neighbor tells you.
  • Cold smoke only high quality, fresh fish or meat.
  • Before cold smoking meat, cure it first using salt.
  • After cold smoking, cook the food (at 160 degrees Fahrenheit temperature) and then eat it.

#20 DIY Soup Can Cold Smoker

Don’t expect to cold smoke bacon and fish in this DIY cold smoker. But it sure knows how to infuse that delicious smoky flavor into foods that require less than 3 hours of cold smoking.


So you cure the food to draw out moisture, which prevents the growth of bacteria. And then place the food inside the smoking chamber. Start the cold smoking process. Then just wait for the whole thing to bring about a delicious smoky flavor.

During the process, keep in mind that the temperature should be low as well as controlled (under 40 degrees Fahrenheit). To do that, the heat within the smoker needs to be balanced out with the external cold temperature. Many also add ice inside the smoker chamber; just place it between your food and the firebox on an aluminum drip pan.

No wonder cold smoking is the most commonly done in colder climates!

You also have many risks associated with cold smoking since there’s no cooking involved. The most prevalent one being botulism, which is quite common when cold-smoking fish and sausages. And if you’re pregnant or chronically ill, then it’s best to simply avoid consuming cold smoked food.

But then, all in all, if you’re using the right equipment the right way with safety concerns in mind, there’s no need to worry. And who says that the right equipment always has to be an expensive cold smoker, large or small? You can build your very own inexpensive smoker at home without spending even half of what the commercial models cost nowadays.
