Is it true that (red) wine causes headaches or allergic reactions?
Obviously, you will get a headache if you drink too much alcohol full stop! So quality not quantity is our motto. Unlike white wines, red wines have been fermented on the grapeskins and therefore contain a wider range of constituents. However this area is under-researched and although there are low levels of histamines and sulfur dioxide in all wines, generally they are not enough to provoke an allergic reaction unless you are particularly sensitive (see above for sulfur dioxide). Organic wines have lower levels of sulfur dioxide and this may help some people. However, there is no denying that some people cannot drink any alcohol or certain types of wines. The only advice we can give is to find wines that you can enjoy by trial or error.
