The Bertha Inflorescence is a UK-manufactured charcoal oven built for commercial kitchens that want to cook over live fire with genuine control. It operates across a wide temperature range, from gentle low-heat cooking to intense high-temperature grilling, using charcoal as the sole fuel source. Heat is retained within the walls and roof of the cooking chamber, producing an even, radiant environment that suits a broad range of ingredients and cooking styles — from whole fish and shellfish through to meat on the bone, flatbreads, and vegetables. The unit is finished in a cornflower colour and is constructed from 304 British stainless steel.

In service, the Bertha is well suited to kitchens where live-fire cooking is central to the menu rather than an occasional method. It reaches cooking temperature in around 30 minutes from cold, which suits planned service rather than rapid spontaneous use. Once up to temperature, the enclosed chamber holds heat consistently, making it practical across a full service period without constant fuel management. It is recommended for operations serving up to approximately 40 diners, which positions it appropriately for independent restaurants, boutique hotels, and smaller event catering operations rather than high-volume contract catering environments.

The practical advantages of this style of oven include:

Broad cooking versatility — grilling, roasting, baking, and smoking are all achievable within one unit
Natural moisture retention from the enclosed chamber produces consistent results with meat and fish
The charcoal heat source adds genuine flavour that gas or electric alternatives cannot replicate
Stainless steel construction supports daily cleaning and withstands heavy kitchen use
A distinctive cooking method that can serve as a visible point of difference on the menu

Installation considerations are worth thinking through carefully. The Bertha runs entirely on charcoal, so there are no electrical, gas, or water connections to account for — but extraction is critical. A suitable commercial ventilation canopy with adequate extraction capacity is essential, and any installation should be assessed against local fire safety and building regulations. The unit weighs 67kg, so positioning and access to the installation site should be confirmed before delivery. It is a freestanding unit, and floor protection beneath it should be considered given the heat output from the base.

The Bertha Inflorescence at this capacity level suits independent restaurants, gastropubs, and smaller hotel kitchens where charcoal cooking is a genuine part of the offering. It is less well suited to sites requiring continuous high-volume throughput across multiple sittings, where a larger-capacity model from the Bertha range would be worth considering. The cornflower finish makes it a reasonable candidate for open kitchen environments, though its suitability for front-of-house display should be discussed alongside your ventilation setup.

If you are weighing up whether this size of Bertha fits your service volume, or you have questions about extraction requirements and installation, our team is happy to talk it through with you before you commit.

Frequently asked questions

Is this oven suitable for a restaurant doing multiple sittings per evening?

The Bertha Inflorescence at this capacity level is recommended for up to approximately 40 diners, which typically suits a single sitting or a modest two-sitting service in a smaller restaurant. If your operation runs high-volume consecutive sittings, it is worth discussing the larger-capacity models in the Bertha range to ensure the oven can support your throughput without being pushed beyond its design intent.

What ventilation and extraction does the Bertha charcoal oven require?

Because the Bertha burns charcoal, a commercial extraction canopy with sufficient airflow for solid-fuel cooking is essential — standard gas-rated canopies may not meet the requirement. Local fire safety regulations and building standards will also apply, so we would always recommend getting your ventilation setup assessed before installation. This is one of the most common points to clarify before ordering.

What type of charcoal should be used, and how does fuel management work during service?

Restaurant-grade lumpwood charcoal is generally preferred over briquettes, as it produces less ash and reaches temperature more cleanly — though the Bertha is compatible with both. Once the oven is up to temperature, the enclosed chamber holds heat well enough that fuel top-ups during a typical service are manageable rather than frequent. Your team will develop a feel for the fuel cycle during the initial run-in period.
