How to make tuak at home, my way.
By: Agustus Sapen
The introduction
Tuak is considered a
cultural drink for the Dayaks. Traditionally,
it is served in most rituals and the first serving is to be offered to the
spirits and deities before public consumption begins. The ritualistic significance of tuak conjures
up various taboos and protocols in making this Borneo Spirit. Most taboos have scientific reasons while
others are respectful gestures.
It is perhaps one of the
reason behind the dwindling numbers of practicing tuak makers, as the taboos lead
to the impression of a complicated process. For some, there are too many things
to consider and the tedious process causes them to drop their intention. The typical ingredients are very simple
though; glutinous rice, yeast, sugar and
water. The experience, trials and errors
make the journey sound complicated, in a
good way. And as with all journeys, to
master the art is to keep a journal and improvising as you conduct various experiments and trials and errors.
The best thing about tuak is there are so many ways you can adjust your ingredients and the methods of making it. Understanding fermentation is key and learning from your first batch provides an insight to your next endeavor. By the time you enjoy your third batch you'll have more creative ideas. Having said that, it helps to get it right at your first batch and the following is my guide.

The preparation
The best way to begin
your tuak making expedition is to take things one step at a time, beginning
with the ingredients. Decide how much
rice you are willing to sacrifice should your experiment turn sour, literally.
I recommend using a pack of one kilo of glutinous rice, which is readily
available in supermarkets. With one kilo
of rice goes one kilo of sugar. This is
the typical amount intended for a fairly matured tuak of more than 3 months and
up to 1 year or more. For short term
maturity, I suggest half a kilo of sugar, so the resulting brew is not too
sweet when consumed early.
For volume, an average
of 4 liters of water is required. I
normally use bottled drinking water. The quantity of water corresponds to the amount of sugar in the recipe and vice versa. The syrup should initially be very sweet to allow the sugar to be converted to alcohol during the fermentation process. A good tuak should have just enough sweetness left as it reaches the desired alcohol level, which is between 15% to 20%. You could
also choose to omit water and just rely on the moisture absorbed by the rice
during the cooking process. Sugar is also
not necessary for this option as there will be enough sugar converted from the
starch contained in the rice. Well,
maybe a spoonful of sugar will do. The
resultant brew will be a pure rice brew; full body with distinct rice flavor,
unless your rice was a little burnt to start with, then you’ll get a smoky
flavor. Thick rice flavor or diluted
light flavor, the choice is yours.
Economically, the pure rice flavor would cost more because it has a
higher ratio of rice per volume of liquid.
And the star of the
journey is of course the yeast. For a
beginner, I suggest starting with the ‘sweet’ type. They come in round white balls, the size two of
plastic mineral water bottle caps put together.
Sometimes they are shaped like a flat disc so it helps to ask the shopkeeper
for the ‘sweet ragi’. One kilo of rice
requires 3 pieces of yeast. You can get them from the Chinese medicine
shop. If you’re in Malaya, ask for ‘ragi
tapai manis’ or ‘chao peng’. If you’re
in Sarawak, ask for ‘ragi tuak, manis’. Don’t worry if you’ve used too little
yeast because these buggers are able to multiply and expand efficiently. Too much yeast on the other hand will affect
your tuak flavor because yeast are made of many spices, some even contains
dried chilli.
Assembling your utensils
Now that we have an
estimate of the ingredients, it is easy to plan for our utensils. The key word is hygiene and volume. For a kilo of rice with 4-5 liters of water,
you’ll need about 6 liters of volume.
Use a new 10 liter food grade tupperware for easy mixing of ingredients.
Traditionally, a ceramic jar or ‘tajau’
or ‘tempayan’ is used. The thick ceramic
wall helps maintain the temperature during fermentation. The best substitute would be a glass jar with
lid. All utensils must be thoroughly
cleaned and sterilized by pouring boiling hot water on them. You could also use alcohol such as vodka to
disinfect, especially the glass jar because pouring hot water may break the
glass. Make available a broad round tray
or basin to spread the rice thinly, cooling it down to room temperature before spreading
the yeast evenly on top and mixing them thoroughly. You will also need a pestle and mortar or a
blender to pulverize the yeast into fine powder.
The process
The first step is to
cook the rice. This can be done in a
typical rice cooker or in a steamer.
When using a rice cooker, the amount of water shall be a quarter less
than that of normal rice because glutinous rice is softer than normal rice. When using a steamer, the rice must be soaked
in water overnight and steamed on a muslin cloth or banana leaf for easy
handling. Either way, the rice must be
perfectly cooked. Don’t forget to clean
the rice thoroughly before cooking.
Cool the rice on a
broad tray, spreading evenly and thinly for a quick cool and also to ensure
even distribution of yeast powder later.
It is useful to note that glutinous rice is easier to handle when it is
still hot. Therefore, try to get a
really broad tray of plastic basin for this job. It is
important to cool the rice to room temperature because the heat will kill the
yeast and there will be no fermentation thereafter.
While the rice cools,
pound the yeast into a fine powder using a pastel and mortar or blender,
depending on the mess you’re willing to deal with later on. Trust me, the yeast powder is really fine and
boy, do they fly.
Pour the yeast powder
on the thin layer of rice evenly. Mix
the two ingredients well with a sterilized metal spatula. Put the mixed ingredients into a sterilized
container and cover it with the lid or a cloth.
The container must not be air tight to allow carbon dioxide to escape and
prevent pressure buildup. Ensure that no
insect, lizard, dust and dirt are able to penetrate the cover. Eww….
Let the mixture sit
for about ten days, but not more than 2 weeks.
Otherwise the high level of alcohol would kill the yeast and there will
be no reaction when the sugar water is added later.
After 10 days, prepare
the sugar water. Boil 1 kg of sugar in 4
liters of water. As you complete your
first journey, you will gain some idea of your own preferred sweetness and
hence be able to decide if more sugar is required. Let the syrup cool to room temperature before
pouring it to the fermenting rice.
Remember to cover back the Tupperware to prevent contamination. You could install a one way valve (air lock
valve) by putting one end of a small hose at the cover and the other end submerged
in a small bottle of water. This is to
prevent oxygen from entering while allowing carbon dioxide to be released
during the fermentation process. Leave
the mixture to ferment for at least another 5 weeks or until there is hardly
any carbon dioxide bubbles released from the container.
To help in the
fermentation process, you could swirl the watery mixture once in a while. You will notice more bubbling activity
thereafter.
When there is hardly
any bubble released, this indicates that the fermentation process has reached a
plateau stage. Sieve the sediment and
rice fibers out and refill the liquid in the same container or another
container. The strained fiber can be
used to begin another batch of fermentation.
The filtered liquid
can now be served or left to continue with its slow fermentation. At this stage, the liquid resembles barley
drink. This can now be consumed.
However, for a better quality tuak, the liquid is allowed to
clarify. There will be a white layer of
sediment building up gradually at the bottom of the container, a process which
clarifies the tuak naturally. Note that
clarification depends on the ‘somewhat’ completed fermentation process as the
yeasts slowly die out. If fermentation
still goes on at a rapid state, the movement of tiny carbon dioxide bubbles as
a result of fermentation will continue to create an upward current in the
liquid and clarification process is
hindered. However, when enough sediment
is accumulated at the bottom, the resulting liquid is a clearer brew.
Air lock valve
The use of air lock
valve or a one way valve doubles as an indicator tool to determine the rate of
fermentation. The frequency of released
bubbles through the water in the small bottle is directly proportional to the
fermentation activity of the yeast. Slow
bubbles means the fermentation process is slowing down. You will also have a better idea of when to
bottle your tuak; whether you choose to have a fizzy tuak or a stable tuak.
The air lock valve can
also be installed in the beginning of the process, working throughout the end
which is the bottling stage.
Storage
Processing and storing
your fermenting tuak in a clear glass jar helps you to observe the process and
appreciate how yeast works. They are
like your tiny little friends; making your very
own booze. Just make sure there
is room to release carbon dioxide.
Bottling your
fermenting and clarifying brew in an airtight container will cause pressure
buildup due to creation of carbon dioxide as a by-product. At a certain pressure, there seems to be less
yeast activity (no bubbling), until the pressure is released and fermentation
continues, building up pressure in the airtight container again and again. Storing pressurized tuak in the fridge gives
you a fizzy tuak drink. That’s cool too.
For some reason, it
seems that some strain of yeasts die hard and tuak will remain in slow
fermenting stage till there is no more sugar left in the mix. That is why tuak made for maturity is mixed
with more sugar to sustain fermentation process and acquire more alcohol
content.
