In 2011, a Belgian nurseryman, Johan NiCOLAI and his children, focused on obtaining a tasty yellow apple. They then continuously hybridized and isolated more than 15,000 unique seedlings, until they obtained a "nugget", by crossing a very aromatic but complex to produce apple, the Temptation® (Delblush), with an apple with great agronomic qualities, the Pirouette® (Rubinstep).
The marriage is explosive!
The name is obvious: Rubis for its taste, which makes it a little apple jewel, and Gold to highlight its yellow colour.
