The science and magic of wine-making

The same argument applies to viticulture or fruit growing in generalwhere site selection and vine training are based on scientific knowledge to obtain the best quality fruit possible. Frequently wild ferments lead to the production of unpleasant acetic acid vinegar production as a by product.

Various taste components in wine affect wine balance: Studies have shown that, when blinded, even the most experienced wine tasters give different reviews of the same wine depending on their mood or the time of day.

But he can just as easily tie biodynamics to the ideas of University of California, Berkeley, agroecologist Miguel Altieriwhose concern is creating agricultural systems that are both productive and sustainable.

The production of geraniol occurs only if sorbic acid is present during malo-lactic fermentation. It needs amino acids, poly phenols, various B vitamins, acids, and minerals such as phosphates.

Lighter aromatic wines such as Riesling, generally do not go through malolactic fermentation. Because of this, winemakers need to control exposure of fermenting grapes to oxygen. This has the advantage of killing most microorganisms but may affect the flavour of the fruit.

To prepare the fruit, first remove any stalks and leaves — you can remove skins if you want but you will lose lots of colour and flavour.

Is Winemaking an Art or a Science?

For example, a wine maker might add a substance such as clay that the unwanted particles will adhere to. If added after alcoholic ferment it will have the effect of preventing or stopping malolactic fermentationbacterial spoilage and help protect against the damaging effects of oxygen.

Winemakers who are not aware of the mechanics of processes occurring in wine are at a disadvantage because they possess less control over the winemaking process. Unfortunately, the process is very complex, so it is not possible to predict from bottle to bottle when flavour and aroma will peak.

That reliance on nature introduces an element of risk, because the wrong kind of microbe can ruin a wine.
