Raise your hand if you’re obsessed with rich, bittersweet-yet-sweet matcha lattes! I’m a real matcha fanatic too, and whenever I go to a café, I always order a green tea or matcha drink first.
But once you start dieting or managing your meals, café matcha lattes feel like a lump of sugar and a syrup bomb, so I get way too nervous about the sugar and calories 🥺
Even when I tried the low-sugar drinks on the market, they were either watery and grassy, or left that bitter, chalky aftertaste that alternative sweeteners have. It happened more times than I can count.
But finally! I found my forever matcha stick, with 0 g sugar yet a flavor richer and more refined than the ones you buy at cafés 😲✨ It’s the Garu Seonsaeng Zero Sugar Matcha Latte powder that Olive Young shopping lovers have been tossing into their carts!
From an ultra-simple home-café recipe ready in three seconds with one stick to plant-based milk pairing tips for every taste, let me spill it all from a matcha lover’s perspective 🤤🍵


First impressions and packaging of the stick-format matcha powder
The moment I opened the delivery box, the fresh green packaging immediately caught my eye!
Highly portable stick packaging: Powder in a big tub flies everywhere whenever you scoop it out, and measuring it is such a hassle. These are individually packed in easy-tear sticks, one serving each, so the portability is seriously perfect 👍
Easy anytime, anywhere: Pop two or three into your bag or pouch on the way to work, and you can tear one open without scissors at the office pantry, library, or an outdoor picnic and enjoy it right away.
A design you want to keep: The minimalist, trendy design adds instant atmosphere just by lining them up on your home-café shelf, hehe.


Korean organic Jeju matcha and zero-sugar ingredients
When I choose a matcha drink, the things I scrutinize most are the ingredient origin and sugar content. The moment I looked over Garu Seonsaeng’s ingredient list, I couldn’t help but gasp 🤯

The deep flavor of Korean organic Jeju matcha
They say it uses generous amounts of 100% Korean organic Jeju matcha, carefully grown in Jeju’s clear natural environment rather than cheap imported green tea. The particles are as fine as snow, rivaling ceremonial matcha for tea service, and with no artificial flavoring or synthetic coloring, a delicate, refined tea-leaf aroma brushes past your nose without any grassy smell.


0 g sugar and 16 kcal per stick
It’s said to achieve 0 g sugar by blending erythritol and natural stevia in a golden ratio instead of sugar. At just 16 kcal per stick, dieters, weight maintainers, and anyone watching their blood sugar can enjoy it every day with absolutely zero guilt!



Gucci, want a bite too? 🖤🐾
What about stevia’s distinctive bitter finish?
There’s none of the artificial, cooling sweetness or lingering bitter chalkiness typical of drinks with alternative sweeteners. Instead, only a refreshing, clean, pleasant sweetness remains—like syrup that has been carefully made and lightly drizzled in 🤤

Make a matcha latte in three seconds
It’s an ultra-simple recipe that lets anyone become a barista, without complicated tea tools or a chasen (bamboo whisk)!
What you need: 1 Garu Seonsaeng Zero Sugar Matcha stick + 150–200 ml milk or plant-based drink + ice as desired
- Pour cold milk into a glass and add ice. (I skipped the ice because I don’t like drinking it cold 🙊)
- Tear open one Garu Seonsaeng matcha stick and gently shake it in.
- Stir it briskly three or four times with a muddler or straw, and you’re done!
It melts smoothly and evenly even in cold liquid, without clumping or forming lumps, so you can just put it in a tumbler and shake it a few times for a perfect drink 👏✨
Milk pairings for every preference
The biggest appeal of Garu Seonsaeng matcha is that you can customize the base drink endlessly to suit your taste and body!
Nutty goodness overload: oat milk. Its savory grain flavor is a perfect match for the bitterness of Jeju matcha, giving you a satisfyingly rich nuttiness that rivals the signature menu at many specialty cafés 💖
A light fit: almond milk. Highly recommended when you want to cut calories as much as possible! The bittersweet matcha aroma meets the clean flavor of nuts, making it just right for a no-fuss meal snack.
Easy on the stomach: lactose-free milk. Even if regular milk usually gives you a stomachache because of lactose intolerance, shake one stick into lactose-free milk and you can enjoy a smooth latte without that heavy, bloated feeling 👍

How this rich, creamy matcha latte tasted
The instant I took a big sip, I blurted out, “Wow, how can this be 0 g sugar and 16 calories?”
Overwhelming richness: It’s on another level from watery low-sugar drinks that taste like they’ve been diluted with plain water. At first sip, the deep, weighty bitterness unique to organic Jeju matcha gently wraps around your tongue through the nutty milk foam 🤯
Perfect sweetness balance: Then a clean, subtle sweetness arrives, softly covering matcha’s astringency and leaving your mouth refreshed.
Dessert cravings, gone in a flash: I can enjoy the thrill of a rich premium matcha latte that costs ₩6,000–₩7,000 at cafés every day at home for just a few hundred won per serving, so my afternoon low-sugar slump is officially a true happiness recharge 💖
