HolyMate is currently only available at Hackalot, Eindhoven. If you happen to be nearby, while Hackalot is open, we encourage you to try this refreshing beverage.

HolyMate is currently handmade using only six ingredients, yerba mate, water, sugar, caramel brown colouring, citric acid and carbon dioxide. The first step is to weigh all ingredients; the following recipe is per litre, and should be scaled linearly:
- 10 grams of Playadito yerba mate
- 45 grams of white sugar
- 1.08 grams of citric acid
- 0.1 gram of E150A caramel brown
- 500 mililitres of hot water (70 °C)
- 500 mililitres of ice cold water (0 °C)

Place the tea in a large tea bag, and let it steep in te hot water for 7 minutes while constantly agitating the mixture. The tea should become fairly dark. When the tea is done steeping, it should be removed from the mixture. Slowly dissolve the sugar, citric acid and E150A into the tea until there are no solid particles left. Filter the tea until all 'dust' is removed, a coffee filter will work but needs to be replaced frequently. Add the cold water to the tea, and optionally place it in a cold environment such as a refrigerator. Flush out the air using carbon dioxide, and leave the container pressurised with carbon dioxide at 2 bar overnight.

If you decide to create HolyMate yourself, we kindly request that you to use a different branding (logo and name)

HolyMate is currently sold at €0.50 for a glass of 250ml. There is also an option to fill a bottle with 500ml for €1.00. These prices are subject to change.
