OREA Brewer Tritan O2 - Clear

Familiar design, greater capacity

The 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 is consistent, brews delicious coffee, is pocket-friendly, and is incredibly cute. Since the launch of the O1, many people have asked OREA for a larger version 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 that can hold a larger volume of water at once.

Impeccable construction

Finding the right manufacturer that truly cares about quality and detail takes time. In fact, it took OREA almost 5 years. The attention to mold design, polishing, and the details of the injection molding process itself resulted in this perfect object, free of injection marks or flow lines. It is the highest-quality plastic dripper in the industry—absolutely. We dare you to compare this to anything else on the market. Made from a single piece of 100% food-safe, BPA-free Tritan plastic. Carefully manufactured and polished to perfection in a family-run boutique plastic factory. The O1 set the standard for how a plastic dripper should look, and the O2 does the same, just with a larger volume.

High-quality materials

There are some open secrets in the industry about how many companies making "cheap drippers" use incorrect plastic labeling. In fact, many drippers labeled TRITAN are not - they use lower-grade PCTG material. This material has poorer impact resistance, lower optical clarity, and a completely different feel. OREA uses genuine American Eastman Tritan material. Using high-quality materials is important (even if it's more expensive) because we know this material is safe at high temperatures and achieves the expected durability. This material, originally made in the USA, has been used for years in hot and cold water bottles by well-known companies like Nalgene.

One-piece design

The OREA Brewer O2 is a clean, one-piece work of art. Simple, lightweight, and very compact - no moving parts. If you love a distraction-free, easy-to-clean, simple, and flexible dripper, this 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 ledge for flat-bottom filter papers, designed to find the perfect balance between support and airflow. The filter paper naturally sags in the middle, encouraging water flow to be more concentrated through the coffee bed. With this style of dripper, we have discovered the most unique acidity profiles, creating a flow pattern closer to a cone in a shallower flat-bottom bed. It brings a candy-like acidity without sacrificing balance, sweetness, and body. It is a masterpiece that has been widely imitated but never replicated.

Ultimate consistency

This design has been appreciated for years by customers for its consistency in every brew. In a way, this is our most hands-off design, letting gravity decide how the water flows and how the bed performs. We love this inherent simplicity and the stability it brings.

The brewed flavor profile sits between a cone dripper and a traditional flat-bottom dripper. The acidity is brighter and cleaner, but very balanced. Compared to other OREA flat-bottom drippers, this bottom creates a lighter, tea-like mouthfeel, which many people praise. If you are looking for a fuller-bodied coffee, we recommend the OREA Z1 dripper.

Expandability

With the release of the O2 comes new accessories—such as our unique Regulators. The plug-and-play silicone bottom 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 by using accessories, it may offer the most brewing methods and styles in a single dripper.

Comparison between O1 and O2

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

Brewing options

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

• WAVE (Wave filters): WAVE filters are simple, fast, and very easy to obtain around the world. They allow for more bypass and airflow, and create a narrower coffee bed. Usually, with the same parameters, they produce a lower-strength coffee. Many people love 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 provide a higher quality extraction by reducing bypass and creating a wider, shallower bed in the dripper. Many people love that they help create juicy, sweet, and full-bodied coffee because they ensure more water passes 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 right answer for which filter to use. It depends on what you value! We will continue to explore and support a variety of brewing styles for flat-bottom drippers. We love seeing people truly try many (sometimes even strange) methods. This is in line with the OREA spirit—we hope you never stop exploring.

Supply chain choices

OREA manufactures the O2 with a family-run boutique plastic manufacturer in Taiwan. They treat their workers well and fairly, and try their best to source everything locally in Taiwan. They treat their products with special care and respect. We know that 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 to interact with their team at their facility to ensure OREA can continue to bring you the highest quality products.
