CHF AUM → NPS +48 — 83% of investors rate us "smooth, trustworthy, excellent" We started Green Mining because we experienced firsthand how broken the Bitcoin investment market was — cloud mining scams, no real ownership, no accountability.

Wij zijn een start-up gespecialiseerd in het leveren van champagne volledig in de look and feel van de klant. Kortom gepersonaliseerd. Dit doen wij door middel van een speciale wrapping. Uiteraard is dit perfect voor branding, als relatiegeschenk en ter promotie van uw bedrijf. Tevens kan het leuk zijn als kerstcadeau voor het personeel.  Het design valt volledig naar eigen wens in te vullen. De Nederlandse ondernemer Fela Donker werkt samen met het Franse champagnemerk Marc Chauvet. De champagne Brut Tradition is de huisklassieker gebaseerd op fruit en frisheid en constante smaak. Deze champagne vraagt tijdens het blenden de meeste aandacht ​​om "de smaak en stijl van Marc Chauvet" te bestendigen. Om deze reden kreeg dit de voorkeur bij de importeurs en makers. Wijnboeren uit champagne zijn echte "scheppers van Champagne", champenois-wijnmakers, vormen al generaties lang veelzijdige champagnes. Ze bevorderen de expressie van het terroir, met traditionele, milieuvriendelijke landbouwpraktijken met respect voor kwaliteit en het milieu. Clotilde en Nicolas, de huidige eigenaren van Marc Chauvet, behoren tot deze adellijke familie van wijnbouwers. Récoltants Manipulants (RM), ze hebben hun productie volledig onder de knie, van de wijnstok tot de druif, van de sap tot de fles. fela@exclusive-champagne.com tel: +31634112113 & raphael@exclusive-champagne.com tel: +31683053883
