Italian plural word (also colline or collio - singular is colle or collina) for "hill", which is frequently used (for example in the regions of Friuli Venezia Giulia, Liguria, Lombardy and Veneto). In connection with area, DOC or even single vineyard designations, this is always a reference to hillside locations. Wines from a hillside area often have better quality due to better exposure (sunlight). Colli, however, is not an unambiguous term and the altitude cannot be derived from it. These can be small hills, but also mountainous areas above 500 metres above sea level.
Without an indication of colli, it does not at all mean that the area in question lies in the lowlands. Many famous wines come from hillside areas without the addition, e.g. Barbaresco, Barolo, Brunello di Montalcino and Vino Nobile di Montepulciano. In France, Côte (Côteaux) corresponds to Colli. In Piedmont, the top of a hill or vineyard is called bricco. Other names for qualitatively outstanding areas are Bricco, Ronco, Serra, Sori and Vigna. See keywords relevant to the topic under Vineyard.
