Short answer: Get the KINTO OCT Brewer 2 Cups (28881) if you brew for one or two people, and the 4 Cups (28882) if you often brew for three or four. Both are the same porcelain, handle-free cone dripper made in Japan, and both are dishwasher safe. KINTO USA sells them for $23.70 and $26.30. The 4 Cups is larger (130 vs 115 mm wide) and heavier (about 280 vs 230 g). KINTO’s matching OCT jugs mark 2 cups at 300 ml and 4 cups at 600 ml.

How we compare: every spec and price in this article comes from KINTO’s official pages (starting with KINTO USA’s 2 Cups page and KINTO Japan’s product page), all listed under Sources below. We don’t run hands-on tests. Where we quote what people found when brewing, they are Japanese testers and reviewers, and we say so. Last updated: November 2026.

KINTO is a Japanese tableware brand, and OCT is its coffee series built around an octagon. The OCT brewer is a porcelain cone dripper with sharp, faceted sides and a wide, curved rim instead of a handle. It comes in two sizes, 2 Cups and 4 Cups, and two colors, white and black. Apart from size, the two brewers share the same design, material and care instructions, so the choice comes down to how much coffee you brew and which jug and filters you want to pair with it.

Key differences at a glance

  • Batch size: 2 Cups pairs with a 300 ml jug; 4 Cups pairs with a jug marked at 300 ml and 600 ml.
  • Size: 2 Cups is 115 x 100 x 90 mm (4.6 x 4.0 x 3.6 in); 4 Cups is 130 x 110 x 105 mm (5.2 x 4.4 x 4.2 in).
  • Weight: about 230 g (8.1 oz) vs about 280 g (9.9 oz).
  • Price: $23.70 vs $26.30 at KINTO USA, a $2.60 difference.
  • Same on both: porcelain, no handle, wide curved rim, dishwasher safe, made in Japan, white or black.

1. How Much Coffee Each Size Makes

KINTO rates the brewers by cups and doesn’t print a ml figure for the drippers themselves. The clearest guide is the matching glassware. KINTO’s OCT coffee jug 300 ml has a single mark at 300 ml, and the OCT coffee jug 600 ml has marks at 300 ml and 600 ml. KINTO Japan labels those marks as the guide for 2 cups (300 ml) and 4 cups (600 ml).

So in KINTO’s terms, one “cup” is about 150 ml (5 oz). That works out to roughly:

  • 2 Cups (28881): up to about 300 ml (10 oz), one large mug or two small cups
  • 4 Cups (28882): up to about 600 ml (20 oz), three to four small cups or two large mugs

These ml figures are our reading of KINTO’s jug marks, not a brewer spec. If you mostly fill a 12 oz (355 ml) travel mug, the 2 Cups size is on the small side, and the 4 Cups gives you room to spare. Our KINTO Travel Tumbler 350ml vs 500ml guide covers KINTO’s travel mugs.

2. Size and Weight

The 4 Cups is 15 mm (about 0.6 in) wider and 15 mm taller than the 2 Cups, and about 50 g (1.8 oz) heavier, according to KINTO’s figures. Both are small enough for most kitchen shelves. The 2 Cups is the better pick if you want to leave the brewer out on display in a small space. KINTO notes that size and shape vary slightly from piece to piece because of the manufacturing process.

Porcelain is heavier than plastic, and it can chip or break if dropped. If you’re choosing between porcelain and plastic in general, our Hario V60 02 Plastic vs Ceramic guide covers the trade-offs.

3. Design: Octagon Facets and No Handle

Both sizes share the same design. KINTO USA describes it this way: “The brewer draws a large beautiful curve. It is designed so that it can be held easily without a handle, and placing and removing the paper filter is simple.” KINTO Japan’s series page says the whole OCT line is based on an octagon (八角形), with sharp straight lines and small details meant to make brewing and drinking comfortable.

White and black are the same brewer in two colors. The model numbers are 28881 and 28891 (2 Cups), and 28882 and 28892 (4 Cups). KINTO lists both colors at the same price.

4. Matching Jugs and Filters

KINTO sells one OCT coffee jug for each brewer size. Both jugs are heat-resistant glass, made in China, and microwave and dishwasher safe.

OCT coffee jug Fits with KINTO USA price Size Full capacity KINTO’s marks
300 ml / 10 oz (28887) Brewer 2 Cups $13.70 ø85 x H85 x W125 mm (ø3.4 x H3.4 x W5.0 in) 400 ml (13.6 oz) One mark at 300 ml (2 cups)
600 ml / 24 oz (28888) Brewer 4 Cups $16.50 ø95 x H115 x W145 mm (ø3.8 x H4.6 x W5.8 in) 700 ml (23.8 oz) Marks at 300 ml (2 cups) and 600 ml (4 cups)

From KINTO USA (checked November 2, 2026) and KINTO Japan. The “full capacity” is the jug filled to the brim, more than the coffee it is meant to hold. Conversions are KINTO’s.

For paper, KINTO’s OCT pages don’t name a specific filter. KINTO’s own cone-shaped paper filters, the SCS cotton paper filter 2cups and 4cups, come in the same two sizes. KINTO USA says the cotton and wood pulp paper “filters fine coffee powders to bring out a clear, mild taste.” No glue is used on the seam, so KINTO says to fold the paper along the seam before you place it in the brewer, or the seam may open.

5. Total Cost

Setup 2 Cups 4 Cups
Brewer only $23.70 $26.30
Brewer + matching OCT jug $37.40 $42.80
Brewer + jug + 60 KINTO filters $42.60 $49.40
Cost per KINTO filter About 9¢ About 11¢

Our math from KINTO USA prices, checked November 2, 2026. Shipping and tax not included.

Even with the jug and a pack of filters, the gap between the two setups is under $7. So price shouldn’t decide it. Pick by how much you brew at once.

Who Should Buy Which?

Choose the OCT Brewer 2 Cups (28881 / 28891) if you:

  • Usually brew one mug or two small cups at a time
  • Want the smaller, lighter brewer (about 230 g) to keep on display
  • Plan to pair it with the 300 ml OCT jug

Choose the OCT Brewer 4 Cups (28882 / 28892) if you:

  • Often brew for three or four people, or brew two large mugs at once
  • Fill a 12 oz or larger travel mug most mornings
  • Want the 600 ml OCT jug, which is marked at both 2 and 4 cups

A View from Japan

In Japan, KINTO sells these as OCT ブリューワー 2cups and OCT ブリューワー 4cups. KINTO Japan’s OCT series page explains the name: the series is built on an octagon (八角形, “Octagon”). The brewers sell for ¥2,200 and ¥2,420, tax included, and KINTO Japan lists them as porcelain, dishwasher safe and made in Japan. The same 2cups and 4cups naming runs through the matching jugs and KINTO’s cotton paper filters, which makes it easy to keep a set the same size.

KINTO Japan’s own journal offers a simple starting recipe. In an interview about pour-over tips, the coffee shop LIGHT UP COFFEE, with shops in Tokyo’s Shimokitazawa and Kichijoji, used the OCT Brewer 2cups and OCT jug 2cups. Its barista suggests using a scale, pouring water at 16 times the weight of the coffee grounds, and aiming for about 3 minutes until the coffee stops dripping. They praised the OCT jug’s glass handle as clean and easy to use.

Japanese reviewers mostly comment on the design and on how fast it drains. A Japanese home-goods blog brewed one cup in nine drippers, including the KINTO OCT, using each dripper’s size recommended for one cup, 12 g of coffee, 92°C water and a 150 ml target. All the paper cone drippers, the OCT among them, reached the target in about 1 minute 20 seconds, and the testers said the differences were within the margin of error. On Rakuten, the OCT brewer and jug set in the 4-cup size averages 4.75 stars from four reviews. Buyers praise the design and the jug’s handle; one said it drips faster than they expected, and another found the taste fairly clean. A Japanese coffee site that ranked KINTO drippers put the OCT second, praising its looks while noting that porcelain is weak to impacts and needs careful handling.

KINTO OCT Brewer 2 Cups vs 4 Cups: Frequently Asked Questions

Should I buy the KINTO OCT brewer in 2 cups or 4 cups?

Buy the 2 Cups (28881) if you usually brew for one or two people, and the 4 Cups (28882) if you often brew for three or four. KINTO’s own OCT jugs put the 2-cup mark at 300 ml (about 10 oz) and the 4-cup mark at 600 ml (about 20 oz), which is a good guide to what each size is meant to brew. The 4 Cups costs only $2.60 more at KINTO USA, but it is larger and about 50 g heavier.

How much coffee does the KINTO OCT brewer make?

KINTO doesn’t give a ml figure for the brewers themselves. It sizes them by cups, and its matching OCT jugs mark 2 cups at 300 ml and 4 cups at 600 ml. By that measure, the 2 Cups is meant for up to about 300 ml (10 oz) of coffee and the 4 Cups for up to about 600 ml (20 oz). That is our reading of KINTO’s jug marks, not a brewer spec.

What filters does the KINTO OCT brewer use?

It uses cone-shaped paper filters. KINTO’s OCT brewer pages don’t name a specific filter. KINTO sells its own cone-shaped SCS cotton paper filters in the same two sizes: 2cups (27633, 60 for $5.20) and 4cups (27634, 60 for $6.60). KINTO says to fold them along the seam before use, because the seam is pressed without glue.

Can I use Hario V60 filters in the KINTO OCT brewer?

KINTO doesn’t list Hario V60 filters as compatible on its OCT pages, so we can’t confirm a fit from official information. If you want to use filters you already own, check the size before buying. KINTO’s own 2cups and 4cups cotton paper filters are the option it sells alongside the brewers.

Is the KINTO OCT brewer dishwasher safe?

Yes. KINTO USA and KINTO Japan both list the OCT brewer as dishwasher safe. KINTO also says to wash it with care and not to use abrasive cleansers or steel wool.

Does the KINTO OCT brewer have a handle?

No. KINTO says the brewer’s large, curved rim is designed so it can be held easily without a handle, and so the paper filter is easy to put in and take out.

Is the KINTO OCT brewer made in Japan?

Yes. The porcelain brewers are made in Japan, according to both KINTO USA and KINTO Japan. The matching OCT glass jugs are made in China.

What is the difference between the white and black OCT brewer?

Only the color and model number. White is 28881 (2 Cups) or 28882 (4 Cups), and black is 28891 or 28892. KINTO USA lists the same price and size for both colors.
