Wine Grape Growing
FANLEAF. A viral disease of the vine.
FERTIGATION. The process of applying fertilizer through an irrigation system.
FERTILIZER. An inorganic or organic substance applied to provide nutrients.
FIELD CAPACITY. Soil eventually reaches a point where it can't hold any more water, and any excess drains away freely. The soil moisture content after the excess water has drained is the field capacity.
FIELD GRAFTING. Grafting a new variety on to an established rootstock already growing in the vineyard.
FLOCCULATION. The joining together of smaller individual particles of soil, especially clay, into larger units or flocs.
FLORET. The individual flower of a cluster.
FOXY. The distinctive taste of the grapes and wine of some Native American cultivars, especially Vitis labrusca and some of its hybrids.
FRENCH HYBRID. Varieties resulting from crosses of vinifera and native American species made by French breeders.
FRUIT (BERRY) SET. When the vine flowers, a proportion of the flowers are fertilized, or 'set', to become berries, and eventually grapes.
FRUITING WOOD. The vine's one year old wood. This wood will produce the current season's crop.
FRUITING ZONE. A horizontal band running down the row of vines, wherein all of the fruit clusters can be found. Many grape growers will often aim to create a tight or narrow fruiting zone so that certain vineyard operations (such as leaf removal around the clusters and harvesting) can be simplified.
FUNGICIDE. A chemical or physical agent that kills fungi or inhibits its growth.
