I've been doing some reading on Cognac and brandy and found that due to the oak ageing the drink is full of a substance which is also found in raspberries and some other fruits, called Ellagic Acid. This stuff is supposed to be a super antioxidant which has been claimed to stop cancer cells from dividing.
Now, the funny thing is that the French of course (and to be fair ANY producer of wine/brandy) are heralding this because the whole wine paradox raised red wine sales and now if the public at large hears this then brandy/Cognac/Armagnac will of course sell more. Wonder if its the same for whiskey they use Oak casks for ageing ....
Then I found this link.
