When you consider renowned wine regions around the world, one thing is clear. Experts will tell you the wine from that region is great because of the special terroir of that location — that is the soil, the elevation, the weather, the number of sunny days, the wind, rain and other factors that contribute to the development and ripening of the vines that grow well there.
To leverage and protect the brand value of those regions, local rules and national laws have been developed to mandate the use of the appellation, the special name for the wine region.
The rules often specify which grapes can be grown, rules for irrigation, how dense the vines can be planted. Most importantly, they specify what percent of the grapes in a bottle must be from vines grown in that appellation.
