Rancid smoke?

Not sure this is your problem, but I received this in my email today. This article is from the TexasBBQRub Newsletter.

I won't post the whole thing, but the one question no one has asked, is about the drain hole. When you foil the bottom are you remembering to poke a hole in the foil?

If not that could be your problem, or the wood is catching fire or some bad wood.

Fire management and the flavor you get from good fire management is one of the two most important things you can do to get great tasting smoked meat every time you cook. The other flavor adder is the rubs and spices you use to put on the meat you are cooking. Let’s keep on discussing the causes and way to fix the dreaded “stale smoke” syndrome which causes your meat to have a bitter or creosote taste to them when they are eaten.

What causes this “stale smoke?” Funny sounding name but the fact is that until you know what caused this bitter taste on the meat it could happen time and time again to you. It is easy to fix the problem if you just know what to do and make a few adjustments to the pit.

Here is what “stale smoke” is and how you can prevent it and not have to worry about it happening to you in the future. “Stale Smoke” is mostly found in pits that are burning wood as their only source of both heat and smoke flavor (stick burners). It really does not matter what kind of wood you are using to cook with you can still have the “stale smoke” syndrome. “Stale Smoke” is created by not having the smoke pass thru your BBQ pit and across the meat fast enough. Since the smoke is not moving thru the pit at a fast enough rates the smoke actually settles down on the meat and creates this bitter taste or creosote taste in the meat.

You can recognize the chance of having this happen to your meat by looking at the color of the smoke that is coming thru the chimney of your pit. You do not want the thick white smoke or grayish colored smoke exiting your chimney. What you are looking for is what I call clean smoke, an almost clear or light opaque colored smoke coming out of the chimney. Some refer to it as a blue smoke but whatever you want to call it if you are bellowing thick white smoke you have probably experienced the “stale smoke” syndrome at one time or another. It is easy to fix the problem now that you know what the real problem is.

You may think that since you are smoking meat you need the thick white smoke coming out of your pit to give the meat that great smoke flavor. After all that is what you are doing, smoking meat but you don’t need or want that thick white smoke going across the meat and leaving your meat either bitter or tasting like creosote. So actually what you want is just the opposite of this.

You want nice clean smoke and it will be filled with the nice flavor of the wood you are burning and this clean smoke will flavor your meat with the great flavor of the wood and not harm the meat with the gases and chemicals that are being created with the actual burning of the wood.

Well all you have to do is open up the air intake valve on the wood box on your pit all the way open. You want to add as much oxygen to the wood as possible so that it burns cleanly. Choking down the air will actually begin to smother the wood and not let it burn cleanly. So you want to have an active fire in the firebox so the gases and other chemicals created during the burning of wood are burned up and therefore do not get into the cooking chamber of the pit and on your meat.

So first thing is to open up the air intake valves on the firebox of your pit and let the fire burn lively and cleanly. And the other adjustment to your pit will be to open up the damper on the chimney all the way so you are moving the smoke thru the pit at a fairly quick rate. These two adjustments will allow the smoke to go thru your pit faster and avoid the smoke sitting on top of the meat you are cooking which causes the bitterness and/or creosote taste in meat.

But you are asking your self if I am burning a really nice active fire won’t that make the fire hotter than I want and therefore increase the cooking temperature in the pit. The answer is it could but you will need to make a few more adjustments. The adjustments will relate to the amount of wood you are adding to the fire box and at what time intervals you will be adding the logs. A common mistake is made by assuming you need a bunch of wood burning to get a good fire and this just isn’t the case. A great fire in your fire box will be a really nice hot bed of coals and then adding on top of the coals a fresh log every 30 minutes or so to burn really nice and give the meat some nice flavor as it burns. Then it will be part of the nice coal bed and you simply repeat the process adding another log every 30 to 45 minutes as the pit temperature dictates.

 
Hey Jim, in addition to making sure the drain hole is open. I have heard other #3 users put a one inch steel nut under the front of the firebox to raise it up and make it even. I also read where another user enlarged the drain hole from 3/8 to 1/2 inch. I think that might be a little drastic. I am with Greg also did not see where you said you foil the bottom of your smoker and the the top of the firebox? I have only done 3 slabs in my #3 and I used cherry, maple and one charcoal briquette. I had a really good smoke flavor on the meat.
 
For me, the only time I had such an issue was my first smoke with my SI #2. Put 10 oz of wood into it and oversmoked my pork resulting in a very bitter smoke flavor.

OK, Got Divot makers wood coming, gonna play with putting the wood more toward the front, leveling up the burner, and yes, I have been making a drain hole in my bottom foil so that's not the problem. Maybe I just need more practice and experience with this new method. Maybe I'm just used to my stick burner. SI sure is nice in the winter livin in Indy, so I want to get this figured out!

One last thought on this long thread, make sure the foil is not touching the element, I have done this once and it smells.

Practice makes perfect, Jimbo!  Try a couple more smokes and let us know if you are still experiencing rancid smoke.  Cheers
 
Jimbo let us know how the new wood works out for you. I would have bet money on it that the problem was using too much wood.
 
OK, got my new wood from Smokinlicious. I was amazed they even give you a certificate showing the moisture content on the shipping day.

QUESTION: Do you recommend putting the wood between the holes in the wood tray or over the holes? Gonna smoke some ribs at 225 today.
 
I try to put the wood on the solid part of the box and avoid the holes, but I don't think it will matter.  Good luck with the new wood!
 
Thanks for all your help everyone, I have one more question. After the cook is done, should I be left with charcoal or ashes? I will let you know how this comes out. :o

I generally have ashes, but sometimes charcoal.  I guess it depends on the particular chunk of wood, and the temp it's smoked at.  Not sure, though.  As long I get good smoke, I don't care, really.
 
Jimbo, I put a piece of foil in the bottom of my fire box and always have pieces of charcoal left.
 
I want to thank everyone for all the help, I think we have found out that I needed damper wood and maybe less heat on the wood. The ribs were excellent! I used the new wood, and put it out near the end of the element as suggested.  I highly recommend Smokalicious as a wood source also. Gourmet wood for sure and great CS ;D!
 
Jimbo, glad you got it figured out. Now you are ready to see what great bbq your SI can put out.
 
Since I lined the bottom of my smoke box with aluminum foil I don't get ashes anymore ever. I used to get charcoal on one end toward the front and ashes in the back. Now it's just charred wood all the way across. No combustion anymore. Lots better smoke. Lasts longer too. Also I can use either chips or chunks and I didn't have to buy a chip screen for 35 dollars plus shipping. The wood I'm using is from academy and it works fine.
 
Hey Dale I never have gotten ash in the #1, and on the #3 I got some ash towards the back of the box. The #3 had a larger element than the #1 and 3 times more the heating element.
 
Glad to hear the Smokinlicious wood was a hit, Jimbo!  Funny, how something as simple as wood, can make such a difference!

Congrats, now on to the next smoke!
