Wood pellets are biofuels made from compressed wood fibre. In British Columbia (BC), wood pellets are made primarily from the residuals left over from the sawmilling process when logs are converted into lumber and other high-value wood products.

Pellets can be made from any one of five general categories of biomass: industrial waste and co-products, food waste, agricultural residues, energy crops, and untreated lumber.[
Wood pellets are the most common type of pellet fuel and are generally made from compacted sawdust[3] and related industrial wastes from the milling of lumber, manufacture of wood products and furniture, and construction
Other industrial waste sources include empty fruit bunches, palm kernel shells, coconut shells, and tree tops and branches discarded during logging operations.

Pellets 101

Pellets are produced by compressing the wood material which has first passed through a hammer mill to provide a uniform dough-like mass.[15] This mass is fed to a press, where it is squeezed through a die having holes of the size required (normally 6 mm diameter, sometimes 8 mm or larger). The high pressure of the press causes the temperature of the wood to increase greatly, and the lignin plasticizes slightly, forming a natural "glue" that holds the pellet together as it cools.[9]
Pellets conforming to the norms commonly used in Europe (DIN 51731 or Ö-Norm M-7135) have less than 10% water content, are uniform in density (higher than 1 ton per cubic meter, thus it sinks in water)(bulk density about 0.6-0.7 ton per cubic meter), have good structural strength, and low dust and ash content.[8] Because the wood fibres are broken down by the hammer mill, there is virtually no difference in the finished pellets between different wood types.[citation needed] Pellets can be made from nearly any wood variety, provided the pellet press is equipped with good instrumentation, the differences in feed material can be compensated for in the press regulation
There are three general types of pellet heating appliances: free standing pellet stoves, pellet stove inserts and pellet boilers.
Pellet stoves work like modern furnaces, where fuel, wood, or other biomass pellets, is stored in a storage bin called a hopper. The hopper can be located on the top of the appliance, the side of it or remotely. A mechanical auger automatically feeds pellets into a burn pot. From there, they burn at high temperatures with minimal emissions. Heat-exchange tubes send air heated by fire into room. Convection fans circulate air through heat-exchange tubes and into room. Pellet stoves have circuit boards inside that act like a thermostat and to regulate temperature.[41]
A pellet stove insert is a stove that is inserted into an existing masonry or prefabricated wood fireplace, similar to a fireplace insert.
Pellet boilers are standalone central heating and hot water systems designed to replace traditional fossil fuel systems in residential, commercial and institutional applications. Automatic or auto-pellet boilers include silos for bulk storage of pellets, a fuel delivery system that moves the fuel from the silo to the hopper, a logic controller to regulate temperature across multiple heating zones and an automated ash removal system for long-term automated operations.

CookingPellets.com

Since 2006, CookingPellets.com has been producing 100% single hardwood species pellets from American raw materials. As they like to state on their packaging ‘No Fillers! No Oak or Alder’. As such, you should expect to pay a premium for these pellets over hardwood blended pellets.

Perfect Mix contains Hickory, Cherry, Hard Maple & Apple pellets whereas the Longhorn Blend is Mesquite, Cherry and Hard Maple. Note, neither of the CookingPellets blends contains any Oak or Alder.

The other two blends are Gold which is a mixture of Oak, Hickory and Maple along with their Texas blend which is a mixture of Black Oak, Hickory and a small amount of Texas Mesquite. While GMG pellets may seem expensive per bag for blended pellets, note the larger than average bag size of 28lbs.

Knotty Wood

A relative newcomer to the market as they were founded in 2019, Knotty Wood is offering two unique pellet flavours in Almond and Plum that I’ve not previously seen from any other brand. Their pellets are 100% single wood species in each bag.
Based in California, the founders behind Knotty Wood have Almond orchards right on their doorstep. Through developing their own pellet plant they worked on developing the first Almond pellets to hit the market. Both Almond and Plum pellets will produce a sweet smoke profile.
Pellet Flavours: 100% Almond & 100% Plum
Bag Size: 20lbs
Typical Price: $18 to $20 per bag
Louisiana Grills

Louisiana Grills pellets are some of the most widely available, though they are oddly not sold at Walmart. Their New England Applewood pellets are a 40% Applewood to 60% Maple blend and its a similar mixture for their Pennsylvania Cherry pellets. While their pellets may seem a high price for blended pellets, note they are large 40lb bags.
Pellet Flavours: Applewood, Cherry, Hickory, Mesquite, Tennessee Whiskey, Competition Blend
Bag Size: 40lbs
Typical Price: $30 to $46 per bag
Lumberjack

What Lumber Jack do provide which many other pellet blend brands don’t offer is the breakdown of wood species in their blends. For instance, their Apple Blend is 60% Red Oak to 40% Applewood whereas their Fruitwood Blend is 80% Cherry to 20% Applewood. As well as large 20 and 40lb bags for dedicated pellet grills/smokers Lumber Jack also offer smaller 1 and 10lb bags for smoking on a gas grill.

Bag Size: 20 lbs
Typical Price: $20 to $48 per bag
Pit Boss

One of the best value blended hardwood pellets, as you can often find Walmart selling a 20lb bag for under $10. Pit Boss does not currently state their wood species blend percentages, for the price I would predict a 20% fruitwood to 80% Oak mix. They will not produce the most intense smoke flavour, but they are a good budget option.
Pellet Flavours: Apple, Hickory, Cherry, Mesquite, Fruitwood, Whiskey, Classic, Competiton, Charcoal
Bag Size: 20, 30 and 40lbs
Typical Price: $10 to $30 per bag
Rec Tec

Hardwood blend of pellets called Ultimate Blend which is a mixture of Red Oak, White Oak and Hickory.
Pellet Flavours: Ultimate Blend (Red Oak, White Oak and Hickory)
Bag Size: 40lbs
Typical Price: $33 to $35 bag
Royal Oak

Founded in 1953 Royal Oak is the largest producer in the US of natural lump charcoal. Therefore, it makes sense that Royal Oak has been the first to produce 100% charcoal pellets. These 100% charcoal pellets have special attributes that set them apart from standard hardwood BBQ pellets.
Not only will these 100% charcoal pellets produce more smoke flavour, they will produce more heat for grilling/searing and they are also water-resistant! The higher heat output of these 100% charcoal pellets may also be well suited to cooking pizza with pellets where you want the pizza stone to be getting up to very high temperatures for a nice crust. 100% charcoal pellets in any pellet grill will provide more functionality and eliminate the chance of an auger block due to swelling pellets.
Pellet Flavours: 100% Oak Charcoal
Bag Size: 20lbs
Typical Price: $19

Traeger

The Traeger range of blended hardwood pellets currently includes Apple, Cherry, Hickory, Mesquite, Pecan and their Signature blend which is a mixture of Hickory, Cherry and Maple. Traeger pellets are widely available but can be a pricey option since they are 20lb hardwood blended pellets.

Bag Size: 20lbs
Typical Price: $18 to $20 per bag
Weber

Weber does provide the mix details on their pellets. For instance, their Hickory pellets are 40% Hickory and 60% Oak and their Apple pellets are 40% Apple and 60% Maple. Weber pellets are not currently as widely available as other major brands such as Traeger & Pit Boss, and they are priced between those brands.
Pellet Flavours: Hickory, Mequite, Apple, Cherry & Grill Master blend
Bag Size: 20lbs
Typical Price: $17 to $25 per bag
Z

Outside of the Z Grills Oak pellets, it would indeed appear their other pellet flavours are comprised of a hardwood blend. If that is the case at $24 to $30 for 20lb bags Z Grills pellets work out at a pretty expensive option, which is rather odd for a budget pellet grill/smoker brand.
Pellet Flavours: Oak, Hickory, Apple, Cherry, Fruitwood & Competition blend
Bag Size: 20lbs
Typical Price: $21 to $30 per bag
