Frequently Asked Questions
How can I stop iced coffee from diluting at outdoor parties?
Use a concentrated base (syrup or 8–10x cold brew), large ice blocks or reusable gel blocks, and an insulated dispenser. Mix drinks stronger than usual so melting ice doesn’t drop the coffee-to-water ratio, and keep spare ice in a separate cooler to top off cups rather than letting server ice melt into the batch.
Should I use sweetened syrup or unsweetened concentrate for parties?
Sweetened syrups (like DaVinci) are fastest for consistent flavor and fewer mix mistakes, while unsweetened cold-brew concentrates (like Califia or Explorer) give you more control over sweetness and calories. Choose syrup for convenience and unsweetened concentrate if guests prefer customizable cups or you plan to offer alternative milks.
What’s the best ice strategy to reduce dilution?
Make large block ice or use reusable silicone/gel blocks: large blocks melt slower than cubes. Keep server containers shaded and insulated, and store extra ice in a separate cooler to top up glasses instead of adding server ice that has already partially melted.
