    Cactus Jack Offset Smokers

    These offset smokers have been around for over 20 years and was the original premium wood fired offset in Europe, licensed from the smokers seen in southern Texas in the early 90's.
    These heavy duty units are quality from start to finish, they really are a lifetime smoker with lots of cooking options and accessories. 
    These cookers are a statement and constant talking point when cooking for friends and family, so fascinate your guests with unique wood fired BBQ food, as there's nothing like mastering live fire cooking.

    Heavy Duty Construction

    If there's one thing you want from an offset smoker, it's thick steel walls. This is the single most important thing, a thick walled offset smoker will run at an easy consistent temperature once it's heated.
    Cheap offset smokers with thin walls, will loose heat faster than your fire can supply heat, and become impossible to run and manage a consistent fire. 
    A steady heat running through a well built smoker like ours, will cook food faster and better.
    Heat fluctuations will have you frustrated and forever running late on cooks, the better the smoker the easier it is to use.
    Our Cactus Jack offset smokers are built in 7mm steel all round, and weigh in excess of 180 kg.
    A true lifetime BBQ smoker.

    Traditional vs Reverse Flow

    Traditional flow is the heat running from the firebox, through the cooking chamber and out of the chimney, simply right to left. This diagonal heat path of the air means you can utilize different temperatures in the cook chamber for ultimate cooking flexibility.

    Reverse flow is a lower smokier cooking technique, where you direct the heat flow under a plate, then back across the food.

    Traditional is our chosen method every time, but if you wanted the reverse flow for a certain type of cook, you will just need our reverse flow kit consisting of a second chimney and steel baffle plates.

    Built By Cactus Jack, Tuned By ProSmoke BBQ

    We've been using these smokers for years, and helped develop this ''Pro smoke'' version of the Cactus Jack you see now.
    We decided the smoker needed to run just a bit hotter and draft faster,  much like the American smokers we imported and tested. 
    The engineers tweaked the existing design and knocked it out the park, these smokers draft, cook and run better than any offset on the market, its the best offset smoker in Europe.  
    All ''Pro Smoke'' versions of the Cactus Jack come per-installed with the ProSmoke BBQ thermometer for easy identification, they are only available from us here in the UK.

    Tune The Smoker To Your Style

    Due to the size of the 20'' Cactus Jack we don't supply a ceramic stone filter as seen on the 16'' versions, as you're able to cook with a fairly even heat profile as it is, but you will find the fire box side hotter than the chimney side.
    This is useful when you have different cuts of meat that require different cook times and heat.

    We can however supply our tuning plates as an extra. This is a system we adopted by the Americans.
    It consists of several steel plates, that you place along the cooker under the cooking grates, this directs the heat under the food and distributes it evenly though the gaps that you specify.
    This also has the benefit of you being able to build a much bigger fire than normal, as you are funneling the heat under the food safely, stretching your refill times.

    An Oversized Fire Box For Grilling

    A feature of the ''ProSmoke edition'' Cactus Jacks is oversize firebox, this not only helps with the air flow and temperature control, it means you have a good size grill at the ready anytime. So why not throw some meat over the fire while you slow cook in the main chamber!
    Over sized fireboxes also help with temperature control, as you are able to move the fire closer or further away from the cooking chamber to control the heat, as well as using the door to control the airflow.

    Our Take On Purchasing An Offset

     Offset wood fired cooking is without a doubt the most satisfying cooking style to master, the flavor profiles you're able to impart to your food are very unique, no charcoal, pellet or gas cooker can match the same taste.
    Being that an offset is such a big purchase we're here every step of the way to advise you on what model would suit you best. 
    Plus the journey doesn't end there, lets say a year down the line you want to upgrade or downgrade based on your usage of the cooker, no problems, we are always willing to trade in/up or down your smoker, at no point are you on your own, buy, sell and forget is NOT what we're about.
    Come and join our ever growing Cactus Jack family.

    Markus Zimmerman

    Cactus Jack CEO

    When we started Cactus Jack over 20 years ago, we knew offset smoking would be popular, it takes BBQ back to its routes and creates a very special cooking experience for your friends and family. 
    We're delighted to be working with Prosmoke BBQ in the UK, they very much have their ear to the ground on all the latest cooking techniques, BBQ gadgets and what people want, we adapt and support them anyway we can.
    We're pleased Cactus Jack UK is now back up, running and here to stay!

    Oliver Giles

    ProSmoke BBQ CEO

    I spent years trying to find an offset smoker to offer our customers.
    We thought we could make a cheaper lightweight model work by upgrading the chimney and modifying the fire box, but none of them worked well and on wood splits alone, they all need a charcoal base to keep going and the temperature swings when cooking were wild.
    We then found the Cactus jack offset, overnight we knew we had a great product, it just needed some minor modifications.
    Now we have the ProSmoke version you see here, and we've been blown away by the feedback we're getting from pit masters, professional chefs and backyard users, we really have something special.

    The Cactus Jack 16” has been a workhorse and my go to smoker for a while.
    The thickness of the metal retains a lot of heat which means I don’t need to constantly tend and watch the fire. They’re extremely high quality and welded together rather than bolted meaning it doesn’t leak. Coming from an Oklahoma Joe highland and other cheap offsets, it’s been a game changer. It’s elevated my cooking and allowed me to cook my best barbecue.

    Warrenty and Support

    money-back icon

    All Cactus Jack smokers come with a lifetime warranty, plus you're covered with our full product and public liability insurance.
    We are not a one man band fabricator that will build you a smoker one year, and be gone the next! we are here to stay and support you with anything you need for your smoker.
    Paint is not guaranteed, due to the extreme heats your smoker will see, this will fade overtime, but there's information in your Cactus Jack guide that will assist you in looking after your smoker going forward.
