Wood Pellets for Pizza Ovens: Which Type Burns Best?

Wood pellets are not all the same, and the type you use in a pizza oven affects both the heat output and the flavour of the finished pizza. This guide covers the main types of food-grade wood pellets, how they differ, and what to look for when buying.

Why Pellet Quality Matters

In a pizza oven, the fuel does two jobs: it generates heat and it contributes to flavour. At 60–90 second cook times, the flavour contribution is subtle but present. More significantly, pellet quality affects consistency. Low-quality pellets with high ash content, binders, or additives produce uneven burns, more residue on the stone, and potentially off-flavours in the food. Food-grade pellets made from 100% natural hardwood burn more cleanly, produce less ash, and give a more predictable heat output from load to load.

The other factor is moisture content. A moisture content of 10–15% is the sweet spot for an efficient burn, and ash content should ideally be around 0.7% and no higher than 1%. High ash content means more soot residue on the stone and inside the oven, which affects both hygiene and cooking performance over time.

Hardwood vs Softwood Pellets

Always use hardwood pellets in a pizza oven. Hardwoods are denser than softwoods, have a higher energy capacity, and produce long-lasting embers ideal for maintaining consistent heat. Softwood pellets are cheaper but burn faster, produce more resin and soot, and are not food-grade in most cases. The cost saving is not worth it.

The Main Hardwood Types

Beech is the standard recommendation for pizza ovens. It burns cleanly, produces consistent heat, and has a neutral flavour that does not compete with the pizza toppings. For Neapolitan-style pizza where the ingredients are the focus, beech lets the dough, tomato, and cheese speak for themselves. ZiiPa's own food-grade beech pellets are sourced from sustainably managed French forests with no binders or additives, and are the recommended fuel for the Piana.

Oak is the other widely used option. Oak burns very hot, is easy to source, and is considered one of the safest and most reliable choices for pizza ovens. It imparts a slightly stronger smoky flavour than beech. For traditional Neapolitan-style pizza, that smokiness is authentic. For lighter toppings, it can be more pronounced than beech.

Fruitwoods such as apple and cherry burn at a slightly lower heat than beech or oak and produce a sweeter, milder smoke. They burn more quickly and produce less long-lasting embers than oak or beech. They are worth experimenting with once you are comfortable with the oven, but they are not the most practical choice for a compact pellet oven running at 400°C where consistent, sustained heat is the priority.

Hickory produces a strong, intense smoke flavour. It works well for meat but can overpower the delicate flavours of a pizza. Worth experimenting with in small quantities, but not the go-to for regular pizza sessions.

What to Avoid

A few things that will cause problems in a pizza oven:

• Pellets with binding agents or chemical additives. These produce off-flavours and more residue. Always check the packaging for 100% natural hardwood.
• Softwood pellets or heating pellets not rated for food use. These are not food-grade and are not suitable for cooking.
• Damp or stored pellets. Moisture causes inconsistent burns and affects oven temperature. Store pellets in a cool, dry place and reseal the bag between sessions.
• BBQ or smoker pellets designed for long, low-temperature smoking. These are optimised for different conditions and will not perform the same way at pizza oven temperatures.

Pellet Size

Most compact pizza ovens, including the ZiiPa Piana, are designed for 6mm wood pellets. This is the standard size for food-grade pizza oven pellets and what ZiiPa's own beech pellets are. Check your oven's manual before using a different size, as larger pellets may not feed or ignite correctly in a compact fuel drawer.

How Much Do You Need?

A compact pizza oven running at full temperature uses approximately 200–250g of pellets per pizza. A 5kg bag covers around 20 full pizza sessions. For a longer session of 8–10 pizzas in an evening, expect to go through around 2kg. It is worth having more than you think you need, particularly in colder weather when the oven works harder to maintain temperature.

Storage

Keep pellets in a cool, dry place away from moisture. Damp pellets burn inconsistently, produce more smoke, and can affect oven temperature. Most food-grade pellet boxes have a resealable opening. If yours does not, transfer unused pellets to an airtight container between sessions. The ZiiPa Donato pellet dispenser stores pellets cleanly and lets you pour directly into the fuel hatch without handling a bag mid-cook.

ZiiPa's food-grade beech pellets come in a 5kg kraft box with an integrated dispenser spout, sourced from sustainably managed French forests with no binders, fillers, or additives. They are the recommended fuel for the ZiiPa Piana.
