Studies show growers can change flavor, color, and even aromas of different wine varietals by altering the amount of water and sunlight the vines receive.
With this knowledge, Dr. Andrew Reynolds from Brock University in Ontario, Canada says wine grape growers can grow different varieties such as reds and gewürztraminers side by side.
"We can map vineyards for yield, and pretty well all aspects of fruit composition and flavor compounds," Reynolds says.
Reynolds shared his recent findings at the Washington Association of Wine Grape Growers Convention.
Research has also found removing some grape leaves at certain times during the growing season can affect characteristics of Rieslings and red wines.
