Cold brew coffee (1 piece)

Choose plain, unsweetened cold brew; request no flavored syrups, sugar, honey, or sweetened cold foam.

Replace sweetened milk or creamers with an unsweetened option such as plain milk, unsweetened soy milk, or unsweetened almond milk; check labels for added sugars.

Drink the cold brew with or after a balanced meal rather than on an empty stomach, especially if caffeine tends to raise your readings.

Reduce the serving size or dilute the cold brew with water or ice, then reassess your response.

Try half-caf or decaf cold brew, since caffeine itself can raise glucose for some people even without added sugar.

Take a brief easy walk after drinking it, if appropriate for you, and compare readings across a few occasions to identify the version and dose you tolerate best.
