What Our Clients SayAbout Our Products
"The soy sauce you make is an exceptional product that has changed my perspective on the subject and opened up a whole new world of flavors that I had never experienced before. The subtle seasoning of the ingredients opens up so many possibilities... Thank you so much for introducing me to them."
Pierre HerméPierre Hermé Paris
“Having grown up with green lentils from Le Puy, I discovered a new way to enjoy this legume thanks to Eri's work with lentil miso. I also love the subtlety of the soy sauce, which takes on an Auvergne flavor with grains from Limagne. A wonderful encounter between enthusiasts...”
Jacques MarconMaison Marcon, Saint-Bonnet-le-Froid
"It's very, very good. It's a sauce I can consume almost as is. It's very aromatic,
smooth, refined, and very pleasant.
I think it's an excellent product. And best of all, you can find it in France, which doesn't hurt."
Thierry MarxSalon du Bon
"I really loved and was shocked by this soy sauce. You can taste the living, natural ingredients that go into it. It really has a different energy and a more than delicious taste. I also find it very well balanced. It's more than a soy sauce for me. It's a jewel. Many thanks Eri-San for this rare and exceptional work."
Xavier PensecHinoki in Brest
"What appealed to me first and foremost was the approach of highlighting production techniques from your country of origin with products from your adopted country and even region."
Of course, there's also the organoleptic quality of your products and the diversity of tastes that we find in relation to the basic legumes used, and finally the sympathy and benevolence that you maintain with us, your customers, which for me is one of the main criteria in the choice of suppliers.
