Tequila Vs. Red Wine

I have a really odd reaction to red wine, and I am completely unsure why.

I can have 3-4 (Tequila) cocktails over the course of 2 hours and feel FINE, walk in a straight line, count backwards, etc.

If I have ONE glass of red wine (otherwise sober), I am GONE. I am borderline slurring, I get the spins, I sometimes have to lay down. I went to a wine tasting with a full (sober) stomach and I had 3 “quarter” glasses (3/4 of a glass) and I had to hold my husbands to stabilize me as I walked out.

I am befuddled by this, as most people describe the opposite. I am a woman in my 20s, if that changes anything.

Could there be anything that could cause this distinction?
