The 2013 Harvest Report of the Wine Institute is in and there is agreement by vintners from Mendocino county in the north to Temecula Valley in the south that this year's vintage will be exceptional. 
The harvest was easy and bountiful with yield increases in almost every appellation.  Last year total tonnage of the harvest was four million tons and that amount may increase slightly this year, slightly lower in coastal areas but increases in interior regions.
The 2012 vintage was considered outstanding and many vintners are saying that 2013 harvest will make it two exceptional years in a row for quality wines.
California is the world's fourth largest wine producer and exports are growing continually.
