How to make yerba mate cold or hot with frozen cubes
Compare hot and iced drinks made from the same batch of brewed, frozen yerba mate without assuming a standard cube size.
Frozen brewed yerba mate cubes offer a way to finish a drink with hot or cold water. The useful starting point is the batch you actually made: its cube size, the number of cubes used, and the water added. No universal one-cube serving or water ratio has been established for Yerba Melt.
Start with the same brewed batch
Use cubes from one labeled batch if you want to compare the two finishes. Record the tray and fill level, since two trays can produce different cube volumes. The cube-size and dilution worksheet helps keep cube volume and added water distinct.
NIST's culinary measurement guidance explains how to read liquid volume on a level surface at eye level. Nevada Extension's recipe-development guidance supports recording ingredients, quantities, yield, and repeat tests. Neither source establishes a mate-cube recipe or serving size.

Keep the fields blank until you make the drinks. The finished level while cubes are still present is not the same reading as liquid volume after they melt.
A hot finish
Choose a mug intended for hot drinks and use hot water appropriate for that vessel. Add cubes from your recorded batch, then note the water added and the finished drink after the cubes melt. The exact amount and mixing sequence need a real kitchen test before they can be presented as product instructions. The frozen-cubes-in-hot-water guide goes further into what remains untested.
An iced finish
Use a glass with cold water and, if you like, ice. Add cubes from the same recorded batch and note added water separately from any extra ice. Compare the finished drink only after the mate cubes have melted. There is no verified need for a room-temperature splash first.
The Argentine National Yerba Mate Institute describes iced mate cocido as a hot infusion that is cooled for cold service; its Spanish mate cocido page is the same source family. Frozen brewed cubes are another preparation format. Those pages do not establish a cube count, water ratio, or melt time.
What a useful comparison can tell you
You can record which version you prefer from your own batch. That observation does not measure caffeine per cube, prove a standard serving, or predict how a future product will taste. For the wider concept, see what frozen yerba mate means here and the cold yerba mate guide.
Yerba mate contains caffeine. If a packaged Yerba Melt serving becomes available, its portion and caffeine information will need to be established from that specific product. Join the waitlist to tell us whether you would use a hot finish, an iced finish, or both.
