We will want less beef and punch in the wines and more balance and elegance. It is less important to reach a high alcohol level and more important to find an equilibrium between fruit and the other components in the wine. Wineries will experiment with yeast that produces less alcohol (yes, there is), grape varieties that produces less sugar but still ripe grapes, techniques for removing alcohol from the finished wine etc. (At the same time, one should remember that a high alcohol level is not in itself contrary to a well balanced wine. There are many well balanced wines with high alcohol levels. It is mostly a question of competent wine making. An in truth, if you think about the health effects, or drinking and driving and such things, does it really matter if it is 12.5% or 13.5%?)
