What the archived formula actually establishes
The current page lists 1 cup coconut water, 1 cup pineapple juice, and 1/2 cup vodka. That is a 2:2:1 ratio by volume: two equal parts coconut water, two equal parts pineapple juice, and one part vodka.
What the page does not establish is just as important. It gives no serving count, cup size, final blended volume, ice amount, dilution, or verified yield. Calling the entire mixture one cocktail would therefore be misleading.
Use the ratio only after choosing a serving plan
Before mixing, decide how many adults of legal drinking age will be served, the intended glass size, and the alcohol-by-volume shown on the vodka label. Those inputs are needed to understand how much alcohol each person would receive.
This guide does not convert the archived batch into individual servings or tell readers to multiply it for a party. Mixed drinks can contain more than one U.S. standard drink, and a container’s volume alone does not establish its alcohol content.
Archived preparation method
The archived page puts ice in a blender, adds the three liquids, and blends until the ice is broken up. Tha Munchiez has not documented testing of the ice amount, finished texture, dilution, or yield, so this is presented as the source method—not a newly validated recipe.
Optional pineapple or coconut garnish does not solve the missing serving information. Additional rum, blue curaçao, or other alcohol is omitted from this guide because it would change strength without a verified serving model.
A beach cocktail is not a hydration drink
Coconut water in the ingredient list does not make an alcoholic cocktail a substitute for water. CDC heat guidance emphasizes staying hydrated and limiting alcohol in hot conditions. Bring and drink water separately, stay cool, and do not describe this drink as thirst-quenching hydration.
Do not drive, swim, boat, or operate equipment after drinking.
What would be needed for a true recipe
A future recipe version needs a verified serving count, finished yield, per-serving pour, ice quantity, tested method, and alcohol-strength calculation based on the actual vodka label. Until those facts exist, the honest page is a ratio and serving-planning guide.
