bertha’s key features
Beautiful on the inside, too
Concealed within her magnificent exterior is an insulated ‘fire box’. The ingenious design of this enclosed charcoal grill means Bertha maintains high cooking temperatures (100ºC – 550ºC), prevents heat loss for up to 9 hours, and ensures the food retains all its natural moisture and flavour.Â
Huge, unrivalled capacityÂ
Ribs: up to 48 racks (≈80 lbs) 

Chicken: up to 48 whole birds (≈72 lbs) 

Brisket: up to 12 briskets (≈144 lbs) 

Pork butts: up to 24 pieces (≈240 lbs) 
 

Capacities are approximate and depend on cut size. 
 

With this level of output, the Bertha is perfectly suited to professional kitchens, high-volume restaurants, and event catering.Â
Why people adore Bertha’s smoked meat
Every brisket emerges juicy, every rack of ribs has that perfect pull, and every chicken carries the unmistakable depth of true charcoal smoke. But why?
Reason 1: Bertha infuses the meat with complex layers of flavour – earthy, sweet, and aromatic notes that only wood and charcoal can deliver. Â
Reason 2: Her precise low temperatures break down connective tissue and fat gently over time, transforming even the toughest cuts into melt-in-the-mouth perfection. Â
Bertha doesn’t just make food tender; she creates the unmistakable ‘smoke ring’ – deep colour and signature aroma that signal craftsmanship and care. She then enhances this process in her sealed, insulated chamber, where she locks in moisture and flavour while maintaining stable temperatures for hours. Â
Game, burgers, fish, lobsters, pizzas… is there no end to Bertha’s talents?
In a word, no. Cook breakfast over embers, grill fish for lunch, and Paella for friends in the evening… there is no end to Bertha’s versatility. She adds new and exciting ideas and flavours to your menu, whatever the cuisine. Â
Bertha’s big advantage
Unlike open grills, the Bertha is designed for precision. Not only does she cook up to 40% faster while using less fuel, but her integrated grease management system makes it safer and more efficient for longer. Most importantly, she delivers the flavour-rich, layered flavour that’s impossible to replicate with gas or electric.
