The CLK-151 cup 180ml is a 6oz Japanese ceramic cup built for espresso, tea, and small pours. Use these decision rules to choose it or size up.
Quick answer
The CLK-151 cup 180ml is a 6oz Japanese ceramic cup for drinks you sip slowly and finish while they are still hot: a double espresso, a small filter coffee, a 150-180ml serving of tea, or a dessert-sized portion of something warm. Choose it when you want a cup that feels considered in the hand and on the table. Size up to a 310ml or 430ml mug when you regularly drink more than 180ml in one sitting.
What 180ml actually holds
180ml is about 6oz, which sits between an espresso cup and a standard coffee mug. In practice, that means one double espresso with a little room, a 150ml pour of filter coffee, or a full serving of tea with space left at the rim. Leave roughly 1cm of headroom so the rim stays comfortable to drink from and the outside stays cool enough to hold.
This is a cup for measured servings, not top-ups. If you refill a 180ml cup three times, you are drinking from a small cup three times, not from a large mug. That is the point: the size slows the ritual down and keeps the last sip as warm as the first.
Drinks that suit a small ceramic cup
Espresso and ristretto are the obvious fit, but the cup also works for cortados, flat whites in smaller ratios, and 150ml pour-over servings. Tea drinkers can use it for sencha, hojicha, or a small pot of genmaicha. It also handles warm milk, hot chocolate in small portions, and dessert servings such as affogato or a single scoop with sauce.
Where it struggles is volume. A 300ml latte, a large Americano, or a long tea session will need refills. If that describes your morning, the CLK-151 is better as a secondary cup for afternoon or weekend use than as your only cup.
How CLK-151 compares to other small Kinto cups
The CLK-151 cup comes from CERAMIC LAB, a collection developed with craftsmen in traditional Japanese pottery villages. The catalog describes roughness and delicacy as its expressive elements, and notes that the clay-to-glaze ratio and firing conditions are controlled closely. That is why the surface has texture rather than a uniform shine.
If you want an even smaller pour-over cup, the SCS-S03 mug 110ml is a porcelain option from SLOW COFFEE STYLE, designed around slow pour-over coffee. If you want one cup for larger drinks, the CAST milk mug 310ml or CAST cafe latte mug 430ml covers more volume with the same handle and rim logic. The 180ml CLK-151 sits between them as the middle size.
Material and care decisions
The CLK-151 is ceramic, so it holds heat well and feels substantial in the hand. Treat it like any glazed ceramic cup: hand washing is the safest route, and if you use a dishwasher, place it away from heavy items that can chip the rim. Avoid sudden temperature changes, such as pouring boiling water into a cold cup straight from the freezer.
The SCS-S03 mug is porcelain and the catalog lists it as microwave-safe. If you routinely reheat drinks, check the care details for the specific cup you choose rather than assuming all Kinto cups behave the same way.
Decision rules for choosing a small cup
- If your drink is 180ml or less: Choose the CLK-151 cup 180ml. It fits a double espresso, a 150ml filter coffee, or a single tea serving with headroom for the rim. Best match for measured, slow sipping.
- If your drink is 200-300ml: Choose the CAST milk mug 310ml instead. The extra volume avoids constant refills and the handle angle is designed for a shifting center of gravity. Size up rather than overfilling the 180ml cup.
- If you want the smallest pour-over cup: Choose the SCS-S03 mug 110ml. It is porcelain, part of SLOW COFFEE STYLE, and listed as microwave-safe for reheating. Pick this for espresso-sized pours and easy reheating.
- If you want one cup for everything: A single 180ml cup will not cover large lattes or long tea sessions. Pair it with a larger mug rather than forcing it to do both jobs. Buy the 180ml as a companion cup, not your only cup.
Product facts
- CLK-151 cup 180ml / 6oz: CLK-151 cup 180ml / 6oz is part of CERAMIC LAB, developed with craftsmen in traditional pottery villages of Japan as a modern interpretation of Japanese tableware. The craft background explains the textured surface and the small-batch variation you may see between cups, which is a feature rather than a defect.
- SCS-S03 mug 110ml / 4oz: SCS-S03 mug 110ml / 4oz is porcelain, part of SLOW COFFEE STYLE, and the catalog lists it as microwave-safe. If you want a smaller pour-over cup with easy reheating, this is the more practical choice than the 180ml ceramic cup.
- CAST milk mug 310ml / 10oz: CAST milk mug 310ml / 10oz uses an outward-spanning rim and a handle angle designed to reduce wrist stress as the center of gravity shifts. If you regularly drink more than 180ml, this size solves the refill problem while keeping the same drinking comfort.
