Best Wood for Pizza Ovens: Oak, Ash, Beech and What to Avoid

The wood you burn matters more than you think

People obsess over their dough, their flour, their tomatoes, their mozzarella — and then they throw any old bag of logs into a £1,500 pizza oven and wonder why the crust doesn't taste quite right. The wood you burn is one of the four or five things that genuinely determines how your pizza turns out. It controls the temperature you can reach, the heat you can hold, the flavour the crust picks up, and how much soot you spend the next morning brushing out of the dome.

This is a practical guide to picking, sourcing and storing wood for a pizza oven in the UK. By the end you'll know exactly what to buy, what to avoid, and how to keep enough good wood on hand that you never run out mid-cook.

The two rules that override everything else

Before we get to species: two rules that matter more than which tree the wood came from.

Rule 1: Always burn hardwood, never softwood. Softwoods (pine, spruce, fir, larch) are full of resin. They burn hot and fast, throw sparks, deposit thick creosote in the chimney and dome, and impart an unpleasantly sharp piney aftertaste to anything cooked over them. They can also damage the inside of a pizza oven over time. Hardwoods (oak, ash, beech, maple, fruit woods) burn cleaner, hotter for longer, and produce minimal residue.

Rule 2: The wood must be properly seasoned or kiln-dried. Freshly cut 'green' wood is up to 60% water. It hisses, smokes, burns cold and creates dense black soot. Properly dried hardwood is below 20% moisture content — ideally 12–18%. It catches fast, burns hot, and produces a clean flame.

Get those two right and you're 80% of the way to perfect pizza wood. Now let's look at the specific species.

The best woods for pizza ovens, ranked

1. Oak — the gold standard

If you can only buy one type of wood, buy oak. It's dense, burns hot and slow, holds heat exceptionally well, and produces a clean flame with minimal sparking. The smoke is mild and pleasantly aromatic — you'll taste it in the crust as a faint background warmth rather than an overpowering smokiness.

Oak's high density means each log gives you more cooking time than a lighter wood. A fire built with oak logs will hold the dome at 450°C for noticeably longer than the same fire built with ash or beech.

Best for: All pizza cooking. Long entertaining sessions. Roasting after pizza.

2. Ash — the easy starter

Ash is the friendliest wood for beginners. It catches fast, burns clean, generates plenty of heat, and doesn't spark or pop. It's slightly less dense than oak, so logs burn through quicker, but the trade-off is that ash is much easier to light from cold and to revive when the fire dies back.

Many UK pizza-oven cooks start with ash because it's forgiving — you can build a good fire even when your fire-craft is rusty.

Best for: Beginners. Quick fires. Mid-week pizza sessions where you don't want a long warm-up.

3. Beech — the underrated all-rounder

Beech sits somewhere between ash and oak. It's dense like oak, burns hot, and produces a clean fire with very little smoke. It's particularly good for the high-temperature pizza phase because it generates a tall, hot flame that licks the dome and creates the rolling-flame effect you want for Neapolitan-style cooking.

The only downside is that beech can be harder to find dry in the UK — it benefits from longer seasoning than ash or oak.

Best for: The high-heat pizza phase. Generating that classic dome-licking flame.

4. Birch — the kindling king

Birch is less ideal as a main fuel — it burns fast and not particularly hot — but it's brilliant as kindling and early-fire wood. Birch bark contains natural oils that catch fire almost instantly, even when slightly damp. A few birch sticks at the base of your fire will get things going faster than any firelighter.

Use birch to start your fire, then move to oak, ash or beech once you have a steady flame.

Best for: Kindling. Getting a fire going in cold or humid conditions.

5. Fruit woods — the flavour bombs

Apple, cherry, pear and almond woods are the secret weapons of pizza-oven cooks who want a distinctive flavour profile. They burn slightly cooler than oak but produce a sweet, fragrant smoke that imparts a subtle, complex flavour to the crust.

Apple in particular pairs beautifully with pork-based toppings (pancetta, prosciutto) and with anything featuring sweet onion or roasted peppers. Cherry adds a deeper, slightly tart smokiness that works well with rich cheeses.

The trade-off is cost — fruit woods are typically 30–50% more expensive than oak in the UK. Most cooks use them as a finishing wood: build the main fire with oak or ash, then add a fruit log just before launching the pizza to add a final aromatic note.

Best for: Flavour-driven cooking. Special occasions. Layering aroma into the crust.

6. Hornbeam — the hot burner

Hornbeam is one of the densest UK hardwoods, even denser than oak. It burns extremely hot and very long. The downside is that it's harder to light — you'll need a well-established fire of ash or oak before introducing hornbeam logs.

Use it for sustained high-temperature sessions where you want to push the dome to its peak temperature and hold it for hours.

Best for: Long sessions. Maximum heat. Experienced fire-tenders.

Woods to avoid

Some woods are not just suboptimal — they're actively bad for your oven and your food.

Pine, spruce, fir, larch (any softwood). High resin content, dirty smoke, creosote build-up, sparks, unpleasant flavour. Never use these in a pizza oven, even as kindling.

Eucalyptus. Burns very hot but produces oily, aromatic smoke that overwhelms anything you cook over it. Some commercial pizza ovens in eucalyptus-growing countries do use it sparingly, but for home use it's too aggressive.

Treated or painted wood. Old fence posts, pallets, decking offcuts, old furniture. These release toxic chemicals when burned and will contaminate your food. Never burn anything you didn't buy as firewood specifically.

Damp wood of any species. Even oak burns badly if it's wet. Always check moisture content before using.

Driftwood. Saltwater-soaked wood releases sodium when burned, which can damage refractory materials and produces an unpleasant taste.

Kiln-dried vs seasoned: what's the difference?

You'll see firewood sold as either 'seasoned' or 'kiln-dried'. Both can be excellent — the question is moisture content, not which process got the wood there.

Seasoned wood is air-dried over 1–2 years in a sheltered, ventilated stack. When it's done well, seasoned hardwood reaches 18–20% moisture content. When it's done poorly (or rushed), seasoned wood can still be 25–30% moisture — too wet for good combustion.

Kiln-dried wood has been mechanically dried in an industrial kiln, usually reaching 12–15% moisture. It's reliable and ready to burn immediately. The downside is cost (typically 15–20% more than seasoned).

For a pizza oven, where you want maximum heat and minimum smoke, kiln-dried is the safer choice. If you can find genuinely well-seasoned wood from a trusted supplier, it'll be fine — but the consistency of kiln-dried makes it worth the premium.

Always ask for the moisture content or use a moisture meter (£15–25 on Amazon) to check before buying in bulk.

How much wood will you actually use?

A typical pizza session uses 8–12kg of wood:

• Heat-up (20–30 minutes): 4–6kg
• Cooking 6–10 pizzas: 3–5kg
• Roasting after pizza (optional): 2–3kg

A 20kg bag of kiln-dried hardwood will give you 1–2 cooking sessions depending on duration. UK prices are typically £8–£12 per 20kg bag for kiln-dried oak, ash or beech. Fruit woods run £12–£18 per 10kg bag.

Over a typical UK pizza season (April to October, roughly two cooks per month), you're looking at 12–16 sessions and 200–350kg of wood. Budget around £120–£200 for a full season's supply.

Storing wood properly

Wood storage is half the battle. The best wood in the world is useless if it sits outside in the rain for two weeks.

Three requirements:

1. Off the ground. Use pallets, bricks or a purpose-built log store. Wood in direct contact with damp soil absorbs moisture from below.
2. Airflow. Don't pack logs tightly together in a sealed box. They need ventilation to stay dry. A log store with slatted sides is ideal.
3. Sheltered from rain. A simple roof or tarp covering the top is essential. Don't wrap the sides — you'll trap humidity.

If you're buying wood in bags, store the bags in a dry shed or garage and only open them as you use them. Sealed bags of kiln-dried wood will keep for years.

The right way to build a pizza-oven fire

Briefly, the technique:

1. Start small. A few birch sticks, two natural firelighters, a handful of dry kindling.
2. Build up gradually. Once the kindling is established, add 2–3 small pieces of ash or oak. Let them catch.
3. Move to bigger logs. After 5–10 minutes, add the main fuel logs. Build a small teepee in the centre of the oven to maximise flame height.
4. Push to one side. Once the fire is roaring and the dome is hitting target temperature, push the embers to one side of the oven floor. The other side becomes your cooking surface.
5. Maintain. Add a small log every 15–20 minutes during cooking to keep the flame curling across the dome.

You'll need the right tools: a long-handled poker, an ash shovel, and ideally a turning peel for pizzas. The complete 6-piece tool set bundles everything you need.

Buying wood in the UK: where to source

A few practical pointers for UK buyers:

• Ready to Burn certified suppliers are required by law (since 2021) to sell wood at under 20% moisture content. Always check for the Ready to Burn logo.
• Avoid petrol stations and supermarkets for serious cooking. Their bagged firewood is fine for occasional use but often expensive per kg and inconsistent in quality.
• Local tree surgeons and farms often sell properly seasoned hardwood at much better prices than national retailers — sometimes £50–£100 per cubic metre delivered. Worth investigating in your area.
• Online specialists like Logs Direct, Hotmax and Logpile deliver kiln-dried hardwood nationally at reasonable prices.

One last tip: try different woods

If you've never experimented with anything other than 'whatever was on sale at the petrol station', try this: buy a small bag of oak, a small bag of ash, and a small bag of apple wood. Run three pizza sessions with each as the main fuel. Taste the difference.

You'll notice it. Oak gives a deeper, mellower background warmth. Ash burns cleaner with almost no smoke note. Apple adds a distinct sweetness, especially noticeable on a pizza with prosciutto or sausage. The difference between cooking with the right wood and the wrong wood is the difference between good pizza and unforgettable pizza.
