From Curiosity to Mastery — The Story of Khun Mai
From Curiosity to Mastery — The Story of Khun Mai
In a small local market in Sena, Ayutthaya,
there is a humble coffee shop called Wayla Coffee & Bake.
It’s not big. Not luxurious.But inside, there is something powerful—
a true desire to learn.
Khun Mai — Tidarat Kaownate —
started with almost no knowledge of coffee.
Only one belief:
“There must be more to good coffee than just strength and sweetness.”Her question was simple: “What is truly delicious coffee… by SCA standards?”
That question changed everything.She didn’t come with skills — she came with intention.
From not understanding extraction or ratios,
she learned step by step —one shot, one mistake, one improvement at a time.
At first, she chased the “perfect shot.” But she discovered something deeper:
Coffee is not about perfection. it’s about finding the sweet spot.She learned to read, listen, and control flavor designing each cup with intention.And perhaps most remarkable her milk skills.
From beginner to a level of smoothness and consistency
comparable to a professional instructor.In the end,she didn’t just make coffee. she understood it.From a small shop, she now holds what many cafés lack:
Standards. Understanding. Intention.
Starting from not knowing is never the problem.Choosing not to learn is."Wayla Coffee & Bake, may look small. but it is already home to a true coffee professional.
From Passion to Experience — The Story of Khun Kong & Khun Kate
Mr. Thammaphaiboon Pornwattana (Khun Kong) and
Ms. Kanokwan Auschanalimpakorn (Khun Kate)
come from the world of shipping—and share a deep love for classic Volkswagen cars.
But beyond business and machines,
they carry a vision:
To create a camping space where people can truly relax,
and leave with a memorable coffee experience.
Their journey into coffee did not begin with expertise,
but with honesty.
The first words I told them were:
“You don’t know how to drink coffee…
and you don’t know how to make it.”
And that was exactly the right place to start.Because in the world of coffee,
the true foundation is not brewing. it is understanding taste.
They began with Sensory Skills, learning how to perceive flavor,
how to recognize structure, and how to align with international standards like SCA. Then came a moment that mattered.
“Now I understand.”
Khun Kate said it with confidence.From that point,
they were no longer guessing.They could distinguish intensity,
identify aroma,and explore flavors with curiosity and joy.
What started as a dream for a camping space
is now becoming something more: A place where experience, atmosphere,
and well-understood coffee come together. Because great coffee is not just about making. it’s about truly understanding.
