The argument against bark is that it can cause an inconsistent burn and produce excessive ash. Again, consider a log on a fire. Because they have different compositions, the bark and hardwood burn at different rates and produce different amounts of heat. Furthermore, bark doesn’t burn cleanly, it creates more ash than the hardwood. When that ash builds up, it interferes with your grill’s ability to accurately read the temperature, causing large swings. If too much of that ash builds up in the fire pot, it can cut off the oxygen and snuff out the fire.

In smoke mode the controller is no longer controlled by the thermometer, it merely switches the pellet feeding auger on and off. On time is 15 seconds, off time ranges from 45 seconds at P0, to 165 seconds at P15. Temp and smoke are controlled by the duration of off time: the auger always runs at the same speed. More smoke is produced at higher P settings and lower temp settings because longer off times allow the pellets to smolder. At P0 in smoke mode or "High" in cook mode the auger replenishes the pellets at a faster rate, creating more flame, less smoke.
With a large cooking space and the most advanced cooking techniques, this is easily one of our favorite products among our top ten. While it lacks some of the features that the other grills and smokers in this review have (such as an ash and grease cleanup systems), it does deliver fine-dining quality foods, which is the ultimate goal of every grilling enthusiast. For its price, it offers some of the best features you can find in high-end products.
Although I marked price high. I would buy it again, tomorrow. I was a novice. I had never smoked anything when I bought this. It is amazing and if you asked my friends and family I should have opened a bar & grill. It's grills better than any gas grill u can buy. The YS640 only gets better with time you get good at using it. It's the best cooker on earth. If your considering paying over $800 for a cooker. Spend the money... you will not regret it. My cousins have Traegers.. and they smeared by them. One weekend at my cabin one has ordered his the other don't have the money yet. I have used it a minimum of 2 days a week and have already got my money out of it by not ruining meat. The guys at Yoder have a monopoly. No one makes a cooker that could stand up to it. THANK YOU YODER. YOU HAVE MADE SOME GREAT HOLIDAY MEMORIES FOR ME AND MY FAMILY. Remember if your on the borderline don't know if it's worth a little more. By the 12th month of owning it. You will look at your wife or girlfriend and say "I'm so glad I spent a little extra and got that. It's beautiful.
This grill is mounted on a bracket with a sawhorse design with wheels that provide it mobility in all terrains. It has a steel construction with a powder-coated finish, giving it a great look and a sturdy body. It has a hopper capacity of 18 pounds but it’s enough to continuously cook and smoke food in its 380 sq. inches of cooking area. Its porcelain-coated grill grates give you a no-rust and non-stick cooking experience that you won’t forget.
I did a lot looking around at pellet smokers before buying the ys 640. This thing is amazing! I have been cooking BBQ for about 15 years. I owned a Gator pit entertainer which is made in Houston Texas (stick burning pit) and I currently own a $25,000 Ole Hickory Pit EL-EDX which can cook 700 lbs of BBQ at once. I wanted something smaller to cook for family. The ys 640 turns out PERFECT Q every time! The amount of smoke is just right. Plenty of smoke flavor without over smoking which is very easy to do in my other pit. This is an EXCELLENT product which I strongly recommend.
I purchased my first Traeger Grills over a year and a half ago and now I am on my third grill. I have had the most amazing experience grilling, smoking and baking. I do everything on my Traeger. It accurately holds the temperature, starts up automatically and has convection which cooks my food evenly and thoroughly. I recommend this grill to anybody who’s looking for a amazing cooking experience with little effort and really likes to show off to their friends how good their food tastes. My favorite part is being able to walk away from the grill and not have to babysit it so I can do overnight briskets without even checking them. I love it.
Second, you’ll have to figure out what BBQ pellets you want to use. There are many different brands, blends, and mixes to choose from, and you’ll likely want to do some side by side testing to see what you like best on what meats. My very good friend and BBQ buddy Shane Draper really likes to make his own blends  – using different woods in different proportions depending on what he’s cooking.
As another criterion that we took into consideration, we felt that the pellet grill size was important to include in our selection process. One of the main reasons is because we wanted to share a wide variety of pellet grills that were designed for multiple uses. With that said, other reasons include the size and weight of the grill as well as the price. Meaning, the bigger the grill the more pricey it can become and the more it will weight depending on the material design. However, we also wanted to share compact varieties such as the Green Mountain Grill which is perfect for tailgates and small outdoor events or camping.
I had an American made Traeger for 6 years and after it rusted out I was looking something built for the long haul. The YS 640 is it. Built like a tank it will hold up for years and the extra steel helps retain the heat. Temperature control is spot on and recoverey after opening the lid is amazing. I thoroughly researched all my options and I could not be happier. I cooked steaks the other night in 40 degree weather and had no issues whatsoever. The grille grates are a must and leave beautiful lines. Before you buy anything else, investigate what the other cookers are made of. There really is no comparison.
Up next to find its place in our pellet grill review is the REC TEC’s mini portable pellet grill. It has a 341 square inch cooking surface with 180 degrees to 550 degrees Fahrenheit temperature limit, with 5 degrees increment. But it can easily reach 600 degrees Fahrenheit in full mode. It has a satisfactory pellet hopper capacity and has folding legs. It is great for travel and movement as it is compact and small in size.
While many people enjoy pellet grills, some find it difficult to use pellets to produce true, flavorful steaks and barbecue since the fuel often lacks the same flavors as traditional grills. That smoky, wood flavor many steaks have is not impossible to get with the right pellet grill however. The Z Grills Wood Pellet Grill sports a combined grill/smoker setup with temperature control for the best pellet grilling experience available.
