In which I try to develop a recipe for our own Club-Mate derivative.

My goal is to develop a recipe for an enjoyable Mate-based soda. If eventually found to be good (enough), we might decide to drink our own Mate instead of buying Club-Mate. Whether we do this or not, it is always possible to brew a batch for a party or large event. Who would say no to a keg of home-brew Mate?

Salt might help against bitterness

First Iteration

In this iteration I tried to find out a basic recipe that works, or points towards the right direction. I brewed six different bottles of Mate-soda, based on recipes I found. The plan was to make three basic recipes twice and brew the Mate for either five or seven minutes, resulting in six different batches. The three basic methods were:

  • Brew Mate, dissolve sugar. Add citric acid.
  • Brew Mate, caramelise then dissolve sugar. Add citric acid.
  • Add Mate to the caramelising sugar, then brew. Finally, add citric acid.

This last method is based on the traditional preparation of yerba mate tea.

I gathered a taste panel during one of our meets for a "blind" (They didn't know the recipes) tasting of the several batches I brewed. They kindly gave their feedback, a summary of which can be found below the recipes.

Club-Mate: C


Note: All degrees(°) are in centigrade.

Version 1.
1 liter water (90°)
1 gram citric acid (dissolved)
70 grams sugar (dissolved)
20 grams Mate (brew for five minutes)
(Note: Resulted in rapid expulsion of copious amounts of foam after adding CO2)

1 gram citric acid (dissolved)
70 grams sugar (caramelised, then dissolved)
20 grams Mate (brew for five minutes)

20 grams Mate (brew for seven minutes)
Version 6.

To be uploaded. (Summary: Version 3&6 were most popular)

Second iteration

Build on Version 3&6.
Less sugar (50/60 grams per liter?)
More citric acid(2 grams per liter)
Caramelise further (Let the sugar turn orange-brown, then add Mate.)
Brew for 6 minutes at 70-75°C

Future iterations

Further improve base recipe
Work on a "natural flavour" recipe
Research kegging and preservation techniques

The original Club Mate

Corn syrup
Mate tea extract (0.4g mate in 100ml)
Citric acid
Coffeine flavor (probably just raw coffeine extracted from coffee beans)
Natural flavor
Caramel color (E150d, the bad one)

Found Recipes

po-ru.com: Here’s the recipe for the syrup (yields about 500ml):

50g 	yerba mate (with stems/con palos)
500ml 	water (boiled and allowed to cool slightly)
250g 	unbleached cane sugar
5ml 	lemon juice
To prepare the beverage, mix 1 part syrup with 5 parts carbonated water.

In a small pot, boil ginger and sugar with some water.
Boil remaining H20 in 5 gallon pot. Cool the big pot to 85C.
Add Mate,steep for 5-7 minutes.
Mix back the ginger-sugar mixture to the mate to taste.

Pour mixture into carboys to cool, chill, then carbonate. 

Make magazine (Dave-Mate):

1L water
50mL (3-1/2 Tbsp or 20g) yerba maté tea leaves
15mL agave syrup
15mL simple syrup
1.25g (1/4 tsp.) molasses
1.25g (1/4 tsp.) guarana
0.6125g (1/8 tsp.) citric acid
Drop of orange bitters.
Heat water to 75C/167F, then steep the yerba maté in the water for 5 minutes.
Strain the resulting tea into another container. You may need to filter multiple times to remove all the sediment.
Add the sweeteners, citric acid, bitters, and guarana.


3 gallons water
85g Chai mate tea (from Teavana)
2.5 cups ‘raw’ cane sugar
1.5g caffeine powder (handle with care!)
CO2 (to taste)
Terse instructions:
Sterilize all equipment. Bring water to just under a boil, add tea and sugar, steep for 5-7 minutes.
Cool, add caffeine powder, stir well, then transfer to keg. Float 15psi of CO2 over the mixture,
then release the pressure valve and re-pressurize. Repeat 5 times (to purge oxygen from the keg).
Let sit for 24 hours, to allow the soda to carbonate, then drop pressure to 7psi and enjoy!
