Apple Cider Vinegar Shrub Soda Recipe (Sugar Counted)

A make-ahead apple cider vinegar shrub syrup you dilute into sparkling water, with the sugar per glass counted and fridge storage based on extension guidance.

Fruit, sugar and vinegar in a jar, one spoonful in a glass of fizz.

This recipe is untested by us. Nobody here has tasted it, so you won't find a flavor review. What you will find is a starting ratio, the sugar and sodium per glass worked out from USDA and label data, and what the research does and doesn't say about vinegar drinks. The idea is adapted from Wendy Polisi's ginger apple shrub; the steps are ours. If you want a single glass with no syrup at all, that's apple cider vinegar soda.

The syrup keeps the work to one jar. Make it once, then stir a spoonful into fizz whenever you want a glass, and choose club soda or seltzer depending on the sodium you want. The sugar per glass is worked out below from USDA data.

The Food Science / Lab Kitchen Note

Vinegar is sour because of acetic acid. The FDA's compliance policy for vinegar says cider vinegar should contain 4 grams of acetic acid per 100 mL, and diluted vinegar should in no case fall below 4 percent. Pour that into a jar with fruit and sugar and you get a shrub: a sweet-and-sour drinking vinegar. The bubbles in the glass are carbon dioxide from the sparkling water.

Why fridge, not counter? University of Maine Cooperative Extension, quoted by the Bangor Daily News, says flavor development should happen in the refrigerator. Ask Extension adds that refrigerated cold-process fruit syrup isn't a safety concern as long as there is no mold, and that high sugar, fruit acidity and vinegar together help. We found no sourced guidance on hot-process shrubs, so this page sticks to the fridge method.

Here's the sugar math. It's our calculation, and it rests on an estimate.

• USDA FoodData Central lists granulated sugar at 99.8 g of sugars and 387 kcal per 100 g, with 1 cup at 200 g. So the batch holds about 200 g of sugar.
• We assume the batch ends up as about 2 cups (32 tbsp) of syrup. That's our guess, because the apple adds juice and some liquid stays in the solids.
• 200 g of sugar split over 32 tbsp is about 6.2 g per tablespoon. USDA's cider vinegar entry adds a trace (0.40 g of sugars per 100 g), so we round to about 6.3 g per glass.
• Calories work out to about 24 kcal from the sugar plus about 2 kcal from the vinegar (21 kcal per 100 g), so about 26 kcal per glass.
• By the same assumption, each tablespoon of syrup carries about half a tablespoon of vinegar. Cleveland Clinic's cap of 2 tbsp a day applies to diluted vinegar itself, so this is just a rough comparison, not a medical rule.

Each extra tablespoon of syrup adds another 6.3 g of sugar or so, so the sugar scales with how much you pour. The shrub is sugar-heavy, and we make no low-sugar claim. If you want to track it, use the number for your own pour.

Sodium comes mostly from the fizzy water. One national club soda 7.5 oz can label lists carbonated water, sodium bicarbonate (which is baking soda), salt and potassium sulfate, with 60 mg of sodium (3% DV) per can (Hannaford listing). Scaled to 8 fl oz that's about 64 mg. One seltzer 12 oz can label lists carbonated water only and 0 mg (Stop and Shop listing). The vinegar in a glass adds well under 1 mg. The FDA sets the sodium Daily Value at less than 2,300 mg a day, so 64 mg is about 2.8 percent of it, and the FDA calls 5 percent or less per serving low. Formulas vary by brand, so read your own can.

Three versions, compared on sourced data

This compares published data and our arithmetic. It is not a taste test. "No sourced data" means we found nothing to compare.

Sugar assumes a 2-cup batch and counts added sugar only.

What the research says

Cleveland Clinic. This medical center article is not a study. It says there is no concrete evidence of long-term appetite suppression and that apple cider vinegar might lower glucose a little, but not enough. There's no standard dose, and it advises no more than 2 tbsp a day, diluted. It also warns that acidity erodes tooth enamel, which does not grow back.

Nutrients 2025 meta-analysis. A systematic review and meta-analysis pooled 10 randomized trials of apple cider vinegar in people with type 2 diabetes and/or overweight. The trials lasted 4 to 12 weeks, heterogeneity was high and five studies were at high risk of bias. The authors call it only a possible adjunct for short-term weight management. None of that tested a sweetened shrub, and nothing here is a promise about weight or blood sugar.

Apple shrub recipe: common mistakes

Straining too fast. Fruit solids left in the syrup can make it cloudy or separated. Use a fine-mesh strainer, let it drip and strain again if needed.

Committing to the full batch before tasting. Shrub guides agree the balance is set by taste, not by the recipe. Too sweet, add a little more vinegar; too sour, add sugar or a splash of water; and use less sugar when the fruit is already sweet. Taste a small amount in sparkling water before you adjust the whole jar.

Steeping on the counter. Maine extension guidance says flavor development should happen in the fridge, so leave the jar there.

Substitutions

Nutrition note

The card values are estimates, not measurements: about 26 kcal, 6.3 g of sugar and 64 mg of sodium (about 2.8% of the 2,300 mg Daily Value) per glass with club soda. They're calculated from typical USDA FoodData Central values for granulated sugar and cider vinegar, plus the club soda label above, using the 2-cup batch assumption. The sodium figure uses club soda; with seltzer it's under 1 mg. Apple sugars and any extra sweetener aren't counted.

Storage

Keep the syrup in a clean, closed container in the refrigerator. Ask Extension gave no specific shelf life and said its answer wasn't definite, only that a refrigerated cold-process fruit syrup is not a safety concern as long as there's no mold. Published times for similar syrups disagree widely, from short to very long, and none we found cites an extension, so we give no number. Discard it if you see mold. Ask Extension also describes freezing as a safe option.

Prep once: make the syrup, store it cold, and build each glass fresh.
