Red Table Wine (1 Serving 5 Fl Oz)

Choose a smaller serving of dry red wine (about 120–150 mL) and avoid sweet red wines, dessert wines, sangria, or mixers containing juice or syrup.

Have the wine with a balanced meal rather than on an empty stomach; suitable options include salmon or chicken with non-starchy vegetables, lentils, or chickpeas.

Avoid pairing wine with refined-carbohydrate foods such as bread, crackers, pasta, pizza, or sugary desserts, which may be the main driver of the rise.

Drink water alongside the wine and sip slowly; limit intake to one serving and avoid additional alcohol that evening.

Check your glucose before drinking and for several hours afterward to identify whether the response is from the wine itself, the meal, or delayed effects of alcohol.

If you use insulin or glucose-lowering medication, discuss alcohol intake with your clinician, since alcohol can sometimes cause delayed low glucose even when an earlier reading rises.
