The OREA Glass Brewer with an OPEN bottom is really something special and there's really nothing quite like it out there. We love glass in general and we've made a lot of glass products over the past years. Glass is fantastic because it's recyclable anywhere around the world, durable, and has unique thermal properties. We're also just super excited to bring back a transparent brewer to the lineup since we had to retire the original V3 in Trogamid.
We decided to launch two variations of the Glass Brewer - this being Type A. Type A is designed with a ridge to sit steady on the included base. This ensures perfect stability and it makes it possible for us to use the beautiful coloured bases to match the brewer. Type A is sold together with a base - if you would like an OREA Glass Brewer without a base, please see the Type B.
This glass brewer is hand-shaped in quite a time-consuming process. In fact, when we originally talked to our manufacturing partners about this idea, they said it wasn't possible. Inside the brewer, the surface is flat to keep the geometry intact. On the exterior, there's a ridge so it can sit perfectly level on top of the base. We pushed and pushed to make this happen because we hate wobbly brewers. We make the most consistent brewing tools out there and a wobbly brewer can never truly be consistent.
Over time, we found a way to make it happen - a real triumph for us and our manufacturer. However, making it is not easy and therefore it is also not cheap. We also can't make too many for now, but we hope to find a way to scale these units up. If you are after a more budget-friendly option, please see the Glass Brewer Type B.
We want to be very transparent (no pun intended) in our photography and in this description that because of the handmade process we use and the difficulty to achieve the shape we are achieving, you will see turning and shaping marks on the brewer. They manifest as lines through the body of the brewer and they are a mark of the process - not a defect. We are taking a tube of glass and shaping it into something custom - it requires a lot of steps and a lot of work, the layers being a bit visible. This manifests in different ways across the units, but we want you to be aware. We won't offer free returns for those that are unhappy with these marks, but will accept returns at your cost.
So we want to re-iterate, this is handmade and it has marks of the process within it - and we love it to bits. We hope you will too!
Glass is an interesting material for coffee brewing. It has a relatively low thermal conductivity rate, at around 0.9 W/(m·K) [In comparison, plastic is around 0.33 W/(m·K) and ceramic around 4 W/(m·K)]. In this way, glass is more similar to plastic than ceramic in how quickly (or rather how slowly) it allows heat from the slurry to move through it. However, glass is also extremely radiative - it really sucks at keeping the heat within it. Ceramics and plastic are less radiative and thus hold that heat inside of them for longer.
The combination of low thermal conductivity and high radiative properties make for a very unique material for coffee. It means that it will take heat out slowly but expel it quickly - reflecting the slurry temperature more accurately but not drain the heat out of it quickly. If you measure and compare this to ceramic or plastic, you find a much smoother heat transition, with a less bumpy trajectory, especially comparing to ceramic.
These properties lead to a very unique profile in the cup, where we find a lot of clarity and some excellent qualities to acidity. This doesn't mean that any glass brewer will taste like this one - the flavour profile is a combination of shape, geometry, and material and is unique to this brewer. Definitely worth trying!
A long time ago, we started cutting some of our V3 brewers to create this massive hole and see how they perform. We thought the results were interesting and always planned to release something like this at some point. The OPEN bottom has a ridge to hold the paper in place - so the paper won't just fall through. It allows the paper to bend in the middle, creating a more central tendency to the flow. In early tests, recipes containing some central pouring really worked well for this brewer.
So why the OPEN bottom? Because we tested it, found it gave something different to our classic approach and felt it was different enough to warrant making a unique product around this idea. We hope you will love it too!
No - not really always. While it has the biggest hole of our brewers, there are other factors that contribute to fast flow rates than just the hole size. However, generally it is fast, consistent and produces a magnificent cup.
You won't be able to use conical filters in this brewer as it has a ridge at the bottom. We just want to make this clear as it is sometimes harder to see in photos.
With the help of lasers and CNCs, we craft these beautiful and colourful holders for the Glass Series Brewer. These hold the brewer stable above a cup or server. The two parts do not click together (like in our V3 brewers), rather the brewer sits on top of the base and they are two separate components.
