What’s in Wine?
Wine’s a natural product right? I mean it’s just grapes, with perhaps a bit of added yeast if needed and some of those sulphite things that all the bottles have on them and that’s it….
Well not quite actually, it’s just that wine labelling is badly regulated so the vast majority of ingredients used in winemaking don’t need to be mentioned on labels and as such the vast majority of winemakers when asked won’t admit to any of them… so that begs the question what could be in my wine?
Well obviously sulphites - which are really important - too little of these babies and wine in the bottle will quickly get oxidised and be no good at all, but other things that can be added include various enzymes (to help break down the grape to juice, delay malo-lactic fermentation or break down B-Glucan from mouldy grapes), Acacia Gum (slow precipitation of colour from the wine), Copper Sulphate (prevent reductive taint - rotten eggs smell), Citric Acid (adds acidity to a flabby wine), Metatartaric Acid (prevents deposition of tartrate crystals), Sorbic Acid (stops yeast fermenting), Ascorbic Acid (anti-oxidant in conjunction with Sulphur Dioxide). Plus of course sugar to make sweet or higher alcohol wines in cool climates. If a wine needs extra acid added to it, I think I want to know - it tells me more about the wine, if I find that the wine is too acidic and it’s because extra acidity has been added then it tells me something about the wines made by that winemaker.
In addition to all these additives, other products can be “used” but theoretically are completely removed before the wine is bottled - more on these another time.
The point however is that in no other area of the food industry can you get away with not telling people what you are putting into something they will eat or drink except in the alcoholic beverages market who for whatever reason can use potassium ferrocyanide in winemaking - a pre-cursor to cyanide! AND NOT TELL YOU ABOUT IT! Quite frankly it is disgraceful, at the moment I open a bottle I have no idea so I cannot make a choice whether I want these things in my wine or not - that choice ought to be mine!
