There is a lot of rocket science out there about barbecuing and grilling.
You will find a thousand different people with a thousand different opinions of how to barbecue.
Which can make it a bit difficult to get started
I think the most important thing when it comes to barbecuing is having the the proper smoker or grill and learning how to use it.
Every BBQ is different, trust me, I have about 13 of them and they are all different.
I have to strongly enforce that fact to my wife every time I bring home a new one
so she doesn't kill me!
If you are wanting to learn how to barbecue,
you want to make sure you have the right equipment.
Offset barrel smokers are great for low and slow authentic BBQ. With the heat source in a separate chamber, away from the meat, it makes it very easy to control the temperature and smoke for an extended amount of time. The rectangular shaped grates are perfect for laying out racks of ribs.
The vertical smoker, water smoker, or "Bullet smoker", is another fantastic cooker for BBQ'n
The round grates make them not as convenient for cooking ribs but they do come in many different sizes, all the way up to the 55 gallon UDS BBQ
If you really want a no brainer temperature controlled smoker you can get a pellet smoker
They are electric smokers that are fed with wood pellets. You fill the pellet box, set the temperature turn it on and go crack a beer. The pellets are automatically fed into the heat box slowly giving you a precise amount of smoke and heat for the entire cook. Takes a bit of the fun out of it in my opinion, but I bet they turn out some pretty grubbin BBQ. Being able to duplicate the exact heat and smoke every time would make it a heck of a lot easier to fine tune and perfect your results!
There is nothing wrong with gas grills or Weber Kettle style grills. Trust me I have several of each.
But if you really want to start cooking authentic low and slow bbq you should get a good smoker.
It will make all the difference in the world.
