Forged Gras by Forged By Vow: Lab-grown foie gras
Is this still considered foie gras? Is this still luxurious?
The target consumers of Forged Gras are restaurants that want to stand out by using a unique ingredient, or restaurants that were already selling foie gras, but had to remove them due to bans (Reynolds, 2024)
Given the target consumers, Forged Gras was created specifically as a luxury ingredient
Needs to be marketed as a high-end, expensive ingredient to sustain the business: Producing less volume, but selling at high prices
Considered a luxury, but for different reasons:
The novelty of having lab-grown foie gras
Paying premium prices for an environmentally sustainable product (Reynolds, 2024)
Made by cultured Japanese quail (51% Japanese quail cells) (Forged By Vow, n.d.)
Sold in restaurants in New York, Hong Kong, and Singapore (Lok, 2025; Reynolds, 2024)
Challenges
Expensive:
Lab-grown meat requires expensive materials and the process is difficult to scale (Reynolds, 2024)
Could retail for over $100/kg (Carman, 2024)
Even though Forged Gras caters to luxury restaurants, profit margins are still low and the business is hard to sustain (Reynolds, 2024)
Policy:
Laws requiring lab-grown meats to level their products as "meatless" or "imitations" (Carman, 2024)
Negatively impacts marketing
Success: Forged Gras managed to imitate the texture of foie gras reasonably, while reducing the liver taste (Carman, 2024)
Faux Gras: Plant-based foie gras
Fuah!
Vegetable-based foie gras created by Spanish company, Hello Plant (Foie Gras - plant based, 2024)
Sold out across Spain (Kassam, 2023)
Making plant-based foie gras at home (Faux Gras, 2023; Sunderani, 2025)
alternative cultivation methods
Ethical feeding: Allow ducks to eat as much food as they want, rather than through force-feeding (Youatt, 2012)
But has faced setback from French organisations that foie gras by law requires force feeding (DeSoucey, 2016)
Duck and goose livers produced this way are smaller and less consistent than through gavage (DeSoucey, 2016)
Lipase treatment to expand the liver to produce fatty content instead of force-feeding (Baechle et al., 2025)
Mouthfeel, taste and flavour of lipase-treated foie gras still lags behind commonly accepted thresholds for force-fed foie gras
Keeping birds in cages restrict their movement (Skippon, 2013)
Birds are unable to regulate their temperatures without bathing or swimming (Skippon, 2013)
Unable to stand erect, turn around, or flap their wings (Skippon, 2013)
Force-feeding ducks and geese with a 20-30cm long tube (DeSoucey, 2016)
Lead to posture and gait abnormalities, steatosis, oesophagitis (Rochlitz & Broom, 2017)
Ducks that are force-fed have on average, 1300-5800% higher mortality rate (Four Paws, n.d.; Voslářová et al., 2007)
Pain, discomfort and injuries to the ducks and geese (Rochlitz & Broom, 2017)
Champions of foie gras argue that ducks have unique physiology and do not suffer as humans perceive them to (DeSoucey, 2016)
Some family-run farms take measures to ensure the ducks’ welfare (Heath & Meneley, 2010)
Making sure that the duck is calm and comfortable
Massaging the duck during gavaging to smoothen the feeding process
Ensuring that gavaging is done quickly
Building a relationship with the ducks
Environmental impacts
Keeping birds in close proximity run a risk of the spread of avian flu (DeSoucey, 2016)
Feed production has one of the highest overall environmental impact compared to other components of production (Leinonen et al., 2012)
The overfeeding and longer rearing times of ducks are the main causes of environmental impact (Brachet et al., 2015)
require larger amount of corn/maize for feed production
alternative feeding methods with regards to environmental impact
Use of sorghum instead of maize as more environmentally-friendly (Arroyo et al., 2013)
Reduce potential environmental impacts of the whole foie gras production process
