wine allergies

[winedope]

in addition to the excellent info already posted here : sometimes it takes your body a period of time to react to an allergen. In other words, over time your body can develop a problem with something (be it food/drink or medication, for example) and it can take less and less exposure to create a stronger and stronger reaction to the stimulus- therefore your headache with a smaller intake of this wine. As has been said, it wqould be best for you to pursue this with your doctor- to find out what is really going on...WD
