Q: What happened to Trinity ONE?

A: Our passion for brewing coffee inspired us to create the Trinity ONE, and thanks to our backers on Kickstarter, the project came to life in 2015. 

Unfortunately, the rising cost pressures during and following COVID-19 has made it difficult for our business to continue to manufacture Trinity ONE and maintain a price point that is viable for our retailers and customers.  

So, for now Trinity ONE is discontinued, however there are still currently some units listed from our last production on Amazon in the USA, and some select distributors. Please reach out if you need any assistance in locating the nearest reseller.  

Trinity ONE remains a great passion for us, and we hope we can resurrect it with a brand new production model one day. Please send us a message if you are someone who wants to be kept in the loop on any future production. 


Q: What filters are compatible with Trinity ONE?

A: This depends on the brew method used and personal preference. 

For press method, we recommend that you use the supplied 180mm micron stainless steel disk (Black Edition). If you wish, you can also add Delter Press paper filters and place on top of the supplied stainless steel disk. In short, paper filters produce a very clean cup, and stainless steel tends to let through some finer grounds and oils which can add a texture and mouthfeel to your cup. 

For drip method (pour over), use a Chemex 6-cup paper filter (square or round OK) for large batches of 2+ servings. The Hario V60 2-cup paper filter also works OK, but is best for smaller doses as the structure of brew chamber does not support it as well as the Chemex. 

For immersion (also tea brewing), you can use the Delter Press paper filter or stainless steel disk. You'll need to adjust the grind of coffee to be much coarser for immersion method, similar to french press in order to strain the coffee and filter by gravity. 


Q: How does the coffee taste using the weighted press cylinder?

A: We have had such great feedback from people using the weighted press cylinder for brewing. The result based on our feedback has ranged from people describing a full bodied cup, more 'expressive' and richer coffee, and a 'well-rounded' and extracted flavour. "Tasty", is also a common word we hear which we think is absolutely fantastic. 

The intention of the weighted cylinder by design is to offer you repeatable and more consistent brewing, since the pressure is exactly the same for each brew. 

The weight also offers a unique degree of extraction by applying a mild air pressure which forces the coffee through the filter and into your cup. This results in potential shorter brew times to achieve an optimal strength, or objectively, the recommended measure of Total Dissolved Solids (TDS) (%).

We look forward to more people making the most of this unique feature and taking coffee to places never seen (or tasted) before. 


Q: How does the coffee taste using the drip method?

A: The drip (pour over) brewing method will produce the same taste results as you would expect from the filters being used on their respective products. 

For example, if using Chemex 6-cup paper filters, you should notice a robust and rich flavour with a clean filtering result. You should grind your coffee coarser when using Chemex as the filtering base flow rate is generally slower and can result in clogging or over-extraction if the coffee is ground too fine. 

If using the Hario 2-cup filter, you should notice a leaner body with aromatics that may seem fragrant and 'lifted' out of the cup. Generally, the taste result can also appear 'fruit-driven' if using a filter roast that is on the lighter end of the spectrum. The grind should be finer than when using the Chemex, as the Hario filter paper offers a faster base flow rate. 

The great part about Trinity ONE is the ability to house both filter options and experience the best of both of the above worlds, whilst also being integrated into the appliance with the other brewing functions.


Q: How does the coffee taste using the immersion method?

A: Immersion method on Trinity ONE will produce similar results to a more traditional french press, however without the 'sludge' or fines at the bottom of your cup. You will need to grind coarser to allow the filter to strain under gravity into your cup, and you will also need to make allowance for a longer brew time to reach optimal brewing results. 

Generally, we recommend using the immersion method for brewing tea, as you are able to produce very clean results and have great control over the immersion time by simply turning the flow controller on and off. 


Q: What glass servers or cups are compatible with Trinity ONE? 

A: There is 110mm clearance from below the flow spouts to the black walnut timber base. Hence we recommend using a server with this in mind. As a guide and reference, the Hario 600ml server fits perfectly and can be used for all brew methods. 

The clearance also allows for a standard 12oz coffee cup such as the Keep Cup, or your typical cafe 12oz takeaway cup provided height does not exceed 110mm. 

Q: What scales are compatible with Trinity ONE? 

A: We recommend using a scale that can measure to 1g or 0.1g resolution to suit the base and weight of Trinity ONE, or otherwise a scale for dosing and pre-weighing of coffee. 


Q: How long does it take to brew with Trinity ONE? 

A: Refer to our brewing guide for details, however the press method should be ready in about 90-120 seconds when using the standard design recipe.

Drip and Immersion methods will take longer and subject to the ratio of coffee and water used, including the selected grind coarseness and coffee filter, and personal taste (of course).  


Shipment Questions 

Q: Why is shipping not offered in my country?

A: Trinity Coffee Co. is based in Brisbane, Australia. If you are unable to order directly from our website, it probably means we have a distributor in your country or region. Please check our 'Where to Buy' page for a list of our international distributor partners and resellers. If you have any further shipping questions please contact us. 


Product Questions 

Q: What are the dimensions and weight of Trinity ONE?

A: The dimensions of Trinity ONE are 22.5cm (W) x 15cm (D) x 35cm (H). You should consider an extra 30cm above the unit to allow for insertion of press cylinder.

The weight of the unit when stowed with cylinder is approximately 6.0kg.


Q: What is the weight of the press cylinder?

A: The press cylinder itself weighs 2.25kg which is the determined weight to self-press for all typical filter coffee grind coarseness settings. 


Q: I have received my unit and need support. Where to from here?

A: Please download a copy of the user guide, which includes information on setting up your first brew and also includes troubleshooting and maintenance.
