Editing Agiorgitiko (section)

==Viticulture==
Agiorgitiko tends to produce small clusters of small, thick-skinned berries. The vine is [[List of grape diseases|highly disease prone]] with [[Master of Wine]] [[Jancis Robinson]] noting that "virtually all Agiorgitiko vines planted in Greece are virused." Depending on the virus, and age of the vine, this can lead to issues with [[ripeness (wine)|ripeness]] and [[yields (wine)|yields]] which can affect the resulting quality of the wine.<ref name="Wine Grapes"/>

The grape is a late [[budding (vine)|budding]] and ripening variety that is prone to produce high yields if not kept in check by winter [[pruning]] or [[green harvest]]ing. In addition to its susceptibility to numerous grapevine viruses, Agiorgitiko is also very sensitive to fungal infection from [[botrytis bunch rot]], [[downy (mildew)|downy]] and [[powdery mildew]]. The vine also responds adversely to [[moisture stress|water stress]] which may require some [[irrigation (wine)|irrigation]] in regions where the practice is permitted. In order to limit yields, Agiorgitiko is often densely planted in poor [[vineyard soils]] but growers need to be mindful of the variety's sensitivity to [[potassium deficiency (plants)|potassium deficiency]].<ref name="Wine Grapes"/>

Wine expert [[Tom Stevenson]] notes that while Agiorgitiko vines can withstand heat well, the grape tends to produce better in higher altitude vineyards that are slightly cooler but still sufficiently warm to ensure that the grape fully ripens. The altitude of the vineyard, in particular, seems to have an effect on how much of a "[[spicy (wine)|spicy]] note" comes out in the flavor of the resulting wines.<ref name="Sotheby">T.

===New clones===
For most of the 21st century, growers have been working with Greek wine authorities to produce new virus-free clones of Agiorgitiko that have the potential to resist most grape disease, including botrytis bunch rot, and produce small berries with thicker skins that could ripen to higher sugar levels with most consistent yields. In 2012, several of these new clones were released to Greek wine growers who have slowly begun replanting their Agiorgitiko vineyards.<ref name="Wine Grapes"/>
