OREA Brewer Tritan O2 - Creamy Purple

Familiar design, greater capacity

OREA BREWER O2, also known as the BIG BABY O, is a one-piece flat-bottom dripper designed to brew the perfect cup of coffee for 1-2 people.

Why we made this

The OREA O1 dripper has many fans around the world—and for good reason. It’s consistent, brews delicious coffee, fits in your pocket, and is incredibly cute. Since the launch of the O1, many have requested a larger version from OREA because they prefer larger cups of coffee, or because they are brewing for two (couples, roommates, parents, or in the office). Over the past 1.5 years, we have also been working on developing immersion-style options, which typically require a dripper capable of holding a larger volume of water at once.

PERII Collaboration Special Edition

OREA began collaborating with PERII and its founder/roaster, Ayla, a few years ago to brew coffee at events in Shanghai and Guangzhou. Initially, OREA made a lavender-colored base for the ceramic dripper, but this time we wanted to take it further! Everyone has always loved the exquisite attention to detail behind the PERII brand, and this soft purple has a very unique hue. Beyond this shade of purple, it also holds some of the world's finest coffees, sold in small glass bottles as single doses for coffee enthusiasts everywhere.

Lunar Cycles

Every dripper features a special engraving used by Ayla in her brand, showcasing a full lunar cycle, reminding us to slow down and enjoy the moment as time passes. The distinct purple hue brings a sense of serenity, and its perfect translucency allows us to clearly see the flow of coffee extraction. We absolutely love how this piece turned out and hope you will too!

Impeccable Construction

Finding the right manufacturer who truly cares about quality and detail takes time. In fact, it took OREA nearly 5 years. The attention to mold design, polishing, and the injection molding process itself resulted in this perfect object, free of injection marks or wave patterns. It is unequivocally the highest-quality plastic dripper in the industry—period. We dare you to compare it with any product made by others. Made from a single piece of 100% food-safe, BPA-free Tritan plastic, meticulously manufactured and polished to perfection in a family-run boutique plastics factory. The O1 set the standard for how a plastic dripper should look, and the O2 does the same, just in a larger volume.

High-Quality Materials

There are some "open secrets" in the industry regarding many companies making "cheap drippers" using the wrong plastic labels. In fact, many drippers labeled as TRITAN are not actually made of it—they use lower-grade PCTG materials. These materials have poorer impact resistance, lower optical clarity, and feel completely different. OREA uses genuine Eastman Tritan material from the USA. Using real materials matters (even if it's more expensive) because we know this material is safe at high temperatures and achieves the expected durability. This material, originally manufactured in the USA, has been used for years by well-known companies like Nalgene for their water bottles.

One-Piece Design

The OREA Brewer O2 is a clean, one-piece work of art. Simple, lightweight, and very compact—with no moving parts. If you love a dripper that offers zero distractions, is easy to clean, simple, and flexible, this one is perfect for you.

Original Open Bottom

For years, OREA's original "OPEN" bottom design has been used in OREA's glass, ceramic, V4, and O1 drippers. The open bottom provides a rim for flat-bottom filter papers, aiming for the perfect balance between support and space. The filter paper naturally sags in the center, promoting a more concentrated flow of water through the coffee bed. With this style of dripper, we've found the most unique acidity profiles; it creates a flow pattern closer to a cone in a shallower flat bed. This results in a candy-like acidity without sacrificing balance, sweetness, or body. It is a masterpiece that has been widely imitated but never replicated.

Ultimate Consistency

This design has been praised by customers for years for its consistency in every brew. To some extent, it is the design where we intervene the least, allowing gravity to determine how water flows and how the bed performs. We love this inherent simplicity and the stability it brings.

The brewed flavor profile falls between a conical dripper and a traditional flat-bottom dripper. The acidity is brighter and cleaner, yet very balanced. Compared to OREA's other flat-bottom drippers, this base produces a lighter, more tea-like mouthfeel, which many people highly praise. If you are looking for a fuller-bodied cup of coffee, we recommend the OREA Z1 dripper.

Expandability

With the release of the O2, new accessories have arrived—such as our unique Regulators. The plug-and-play silicone base completely changes the flow pattern and flavor profile of the dripper. One series explores contact time, while another explores immersion (or hybrid brewing), and is compatible with Hario Switch bases. In a sense, the O2 is our simplest dripper, but with the use of accessories, it may offer the most brewing methods and styles in a single device.

Comparison between O1 and O2

These two products are identical in: aperture size, geometry, wall thickness, and material. The only difference is the height of the brewing chamber, which affects overall capacity and filter compatibility. The O2 is a taller device with more room to accommodate more coffee grounds and water. The O1 is designed for single-serving brews, while the O2 has a larger capacity. For single-serving brews, we recommend the O1 due to its moderate size, which allows you to keep your kettle spout closer to the bed. If you frequently brew for two, or are used to using more than 18g of coffee grounds, we recommend the O2.

Brewing Options

The O2 is more flexible, so you can brew in various ways and use different types of filter papers.

• WAVE (Cake Filters): WAVE filters are simple, fast, and very easy to obtain worldwide. They allow for more bypass and airflow, creating a narrower bed. Typically, at the same parameters, they produce coffee with lower concentration. Many people enjoy their ease of use, plug-and-play nature, and fast brew times. The O2 is compatible with traditional WAVE 185 size filters or OREA WAVE 185.

• FLAT (Flat Filters): Flat filters are fun, delicious, and offer higher-quality extraction by reducing bypass and creating a wider, shallower bed in the dripper. Many people like how they help create juicy, sweet, full-bodied coffee because they ensure more water flows through the coffee grounds rather than around them. The O2 is compatible with OREA FLAT 185 / SIBARIST OREA M / SIBARIST MARTIN WÖLFL.

• Experimental Spirit: There is no standard answer for which filter to use. It depends on what you value! We will continue to explore and support multiple brewing styles for flat-bottom drippers. We love seeing people truly try many (sometimes even strange) methods. This is in line with the spirit of OREA—we hope you never stop exploring.

Supply Chain Choices

OREA manufactures the O2 in Taiwan with a family-run boutique plastics manufacturer. They treat their workers well and fairly, and do their best to source everything locally in Taiwan. They treat their products with special care and respect. We know the pricing we give you (or they give us) will never be the lowest—if you are looking for the lowest price, you can buy from other companies. We focus on quality and return value to the supply chain—supporting those who do business the right way. OREA visits this factory 3-4 times a year, interacting with their team at their facilities to ensure OREA can continue to bring you the highest quality products.
