Clone CHGGN87: Our Guilluame Grapevine Nursery proprietary clone. 8 clones were first selected, tested for viruses then put in observation and micro-vinified for 10 years. Chardonnay 87 was selected for its ability to produce delicate and fine wines, with an exceptional mouthfeel.
Rootstock 101-14: 101-14 MGt is very tolerant to chlorosis. It only resists up to 20% of "total" limestone, 9% of "active" limestone and an ICP of 10. 101-14 MGt is also fairly sensitive to soil acidity along with copper toxicity and boron deficiency. This rootstock is sensitive to drought but is fairly well adapted to humidity. It has a ramified root system similar to that of Riparia Gloire de Montpellier. 101-14 MGt absorbs well magnesium and is adapted to fairly deep, clay soils with very little or no limestone and a sufficient water input.
101-14 MGt is very tolerant to the root form of phylloxera and to Meloidogyne incognita and Meloidogyne arenaria nematodes.
101-14 MGt is moderately tolerant to the gall form of phylloxera. It is also fairly sensitive to anthracnose but shows a good resistance to downy mildew.
