Frequently asked questions

How long does Cold-Brew Coffee Tonic with Citrus and Vanilla take to make?

Total time is about 3 minutes (3 min prep + 0 min cook). Most home bartenders find this fits a single afternoon; scale up the batch for parties or pitchers.

How do I store leftover Cold-Brew Coffee Tonic with Citrus and Vanilla?

Refrigerate any leftover cold-brew coffee tonic with citrus and vanilla in a sealed pitcher or jar for up to 3–4 days. Do not reheat — drinks are served chilled. If the recipe uses sparkling water or fresh herbs, hold those back and add fresh just before pouring so the drink stays bright and fizzy.

Can I substitute ingredients in Cold-Brew Coffee Tonic with Citrus and Vanilla?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Cold-Brew Coffee Tonic with Citrus and Vanilla for a different number of people?

The recipe is written for 1 servings. Multiply each ingredient by (your serving target / 1). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
