Varietals were studied more intently to see which vines were the most suitable for a particular area. Around this time, an early concept of terroir emerged as wines from particular places began to develop a reputation for uniqueness. The concept of pruning for quality over quantity emerged, mainly through Cistercian labors, though it would create conflict between the rich landowners who wanted higher quality wines and the peasant laborers whose livelihood depended on the quantity of wine they could sell.[21] The Riesling is the famous example for higher quality of wine.
