A wine expert says storing leftover tipple in a jar keeps it fresh - and a more expensive bottle helps avoid 'wine headaches'. <br /><br />Connoisseur Warner Boin Dowlearn, 30, believes storing leftover wine in a jar with a lid - instead of putting the cork back in it - keeps the wine fresher.<br /><br />She also suggests drinkers can avoid 'wine headaches' by drinking less and keeping hydrated. <br /><br />Warner recommends people have a glass of water between each glass of wine to keep them hydrated.<br /><br />Warner, from Sonoma County, California, US, said: "If you were to put the cork back on a bottle of wine that's half empty you'll see half of the bottle still has oxygen inside it and the cork will still allow oxygen to get into your wine bottle.<br /><br />"You want to reduce the oxygen-to-wine ratio to keep it fresh and to do this I recommend using a jar.<br /><br />"A winemaker that I used to work for told me something similar, he recommended just buying half bottles of wine and then you can keep any leftover wine in there. <br /><br />"There is so much less oxygen in a smaller jar than the rest of a bottle - it will still make your wine taste fresh even a couple of days after you've opened it.<br /><br />"Whereas a day after I open a bottle of wine and I put the cork back on I can tell the difference.<br /><br />"I use this trick all the time, my friends use it, and it is really handy."<br /><br />Warner also debunked the myth that wines get better with age saying "90 per cent of wines are meant to be consumed when you buy them".<br /><br />"Most wines do not get better with taste. I would say that 90 per cent or more are meant to drink now," she said. <br /><br />"The typical wines you will get on your supermarket shelf are not meant to age - it is only the really expensive ones that are."<br /><br />Warner also explained how to stop 'wine headaches' many people endure after drinking.<br /><br />She said: "There are a couple of factors people need to consider when it comes to wine headaches.<br /><br />"It could either be the wine you're drinking or the amount. <br /><br />"If you're having a reaction to wine, it could be the amount of sugar or additives in the wine or the amount we drink.<br /><br />"Dehydration is the number one cause of headaches - make sure you drink water between alcoholic drinks.<br /><br />"Wines contain natural compounds like sulphites, histamines and tannins that some people might have more of a sensitivity to.<br /><br />"What worked for me was keeping a list of all the wines that I was drinking and noting down how I felt after drinking each one of them.<br /><br />"I started to notice that when I was drinking American wines under $14 or $15 I was having negative reactions.<br /><br />"As a result I switch to smaller production wines which include fewer additives."<br /><br />Warner's top tips - <br />- Store leftover wine in smaller jars <br />- Drink water between alcoholic drinks to stay hydrated<br />- Make a list of wines your drinking and note down how you feel after it
