Oh, so soil matters after all…

A new study by German researchers (from the Service Center of Rural Areas) shows that soil type may have a greater influence than climate on the characteristics of wines. This contradicts conventional wisdom. Taking samples of Riesling grapes grown across Germany, researchers put lots of grapes from different vineyards through identical winemaking processes, then compared them based on soil types. What did they find? Riesling gown in Limestone based soils - even when grown hundreds of miles apart in completely different climates - had similar characteristics of tropical fruit and honey with intense color. Meanwhile, Riesling grown in sandstone soils all showed mineral and citrus qualities. Interesting stuff. These results were based on two years of study and are just the beginning. The next phase of the study will look specifically at climate differences. Stay tuned! And for more info, check out the January 2008 issue of Wines & Vines magazine.
