Delter Coffee Press

The Delter Coffee Press is a Unique Reimagining of the Press Coffee Maker & Press Coffee as an Alternative Brewing Method!

The Delter Coffee Press avoids a bitter and inconsistent extraction by controlling the agitation during the coffee brewing process using the Delter Coffee Press unique jet-seal.

This jet-seal keeps the brewing water and the coffee grounds separated until the brewing commences, preventing uncontrolled agitation. When pressure is applied to the plunger, then water and coffee contact is activated, allowing agitation to occur for the first time. This design allows the user to have complete control over the water flow and agitation, resulting in a brew with less bitterness and more clarity.

To brew with the Delter Coffee Press, you need freshly roasted ground coffee and water just off the boil.

Delter Coffee Press Instructions:

1. Place a filter in the Delter cap and rinse with water and discard.
2. Add freshly ground coffee into the Delter coffee chamber (max. capacity 30g).
3. Twist on the Delter cap. 
4. Flip the Delter over onto your cup and start pouring your hot water into the brew chamber, filling to the line.
5. Raise the plunger to dose the exact amount of water required for your brew.
6. Push down on the plunger to activate water and coffee contact.
7. Raise the plunger again to refill the brew chamber for a larger, double-batch serving. 
8. Enjoy!

Using your Delter Coffee Press

Let's start by looking at the design. Not too dissimilar from an Aeropress, on the top here it does have one unique feature that's different. This is a rubber stopper, which I believe is intentional to measure out your coffee grounds but it's only a 6-gram measure.

We're using 12 grams, which is a double use, which it does come in handy but we're going to do it a different way today. Like the Aeropress, you have your top plunger piston. You also have the brewing chamber and then you've got the filter basket, the plastic filter basket that goes on the bottom but then there's also the spot for the paper filter. 

Where it differs from the Aeropress however is this seal that's on the bottom of the Delter. This seal covers the whole bottom of the brewing chamber and has these little jet-like sealed holes, which almost creates something very similar to a shower screen that would be used when extracting espresso.

Let's jump into expressing our filter coffee. First, we're going to want to place our filter basket on top of our glass or our server of choice. You can use just a plain latte glass like I'm using or you can use one of Hario's servers or your mug at home, whatever you choose. Inside the plastic filter basket, you'll see the paper filter. 

Using our pre-boiled water from our kettle and we're going to soak the paper filter. There's a couple of reasons why we do this. It enables the paper filter to stick to the plastic filter. It then also enables any residual paper fibers that are left on the paper filter to wash through into the cup below and then finally that water that does pass through into the cup, that allows the cup to heat up and therefore later on when we are extracting, we're not extracting hot coffee into a cold cup. Then we're going to set that one aside.

Next, we want our plunger to be placed inside the brewing chamber upside down because we need it up this way to pop the coffee in next. 

Now ground coffee, so when you buy the Delter Coffee Press it specifies that you will need 12 grams of ground coffee however I couldn't actually find where it specified what coarseness you'll need. 

At Crema we recommend that you use a medium coarseness grind, which is what we would use for a narrow press and this is just a step up from the espresso grind. 

Pour your ground coffee into the top of the brewing chamber like so and of course as freshly ground coffee as you can get, it does make all the difference. Give that one a little bit of a shake, we want to level it out so the coffee grounds are nice and even on the top, and therefore when it extracts it will be an even extraction. 

Next, take your plastic filter just give that a bit of a shake, just in case there's any residual hot water there and then you're going to pop it back on top of the brewing chamber and make sure you screw that on nice and tight. We don't want any water escaping and then that little bit of residual water that you've got there heating up your cup, you're just going to want to pour that out. 

We're going to flip this one upside down, back on top of our glass, and now we're ready for the water. I'm using the Brewista Temperature Controlled Kettle. These are amazing for so many reasons. It can set the temperature of your water to any degrees Celsius that you choose and then it can hold it there. If you have your water too hot, you can be at risk of burning the coffee and that's gonna really play effect when it comes to the end result.

We've set this water here for 92 degrees. This is about the perfect brewing temperature. If you don't have a temperature control kettle at home, one with the control spout as well is fantastic. We're gonna pour up to the 200ml line and actually says fill next to it,

Delter has made it really easy. You'll notice that at no point do we have to weigh the water going in, which is super helpful. The only point that you will want to weigh something in your coffee at the start. Lastly, this little guy that we were talking about earlier, the black, silicon little rubber topper, that was the scoop for the coffee grounds. Twofold, it sits on top. 

This is really important and you don't think of it until you're actually physically doing it and you're plunging down. Hot steam coming up on your palm is the last thing that you want. So firstly you're going to want to pull it up until it reaches the 50 ml mark. Draw the plunger up so it releases water into the bottom chamber. Then slowly press that down. The reason that we've done this, is we're creating what's called a pre-infusion and this means that that first 50 mils of water is going to evenly coat the ground coffee, and then that will then cause us to have a more even extraction when we push the remainder of the water through the coffee. 

Lastly, we're gonna pull the plunger all the way up, so that now all of our water here is below the plunger. Push the remaining water down into the glass and I recommend not being too forceful with it. Just kind of work with the natural resistance of the Delter. 

Now that we've pushed all the water through, don't be tempted to do what you would normally do with an Aeropress if you're familiar and that is to flick it back up the other way around. If you do so with the Delter, any residual hot water that's sitting down here at the bottom will flick and run down your arm and we don't want you burning yourself. So you simply need to just pick it up and pop it off to the side. 

That's it! Quite a simple process and you're left with a really delicious alternate brew coffee, filter coffee in your own home. The Delter is travel friendly, it's super lightweight and really easy to clean. You simply need to pull it back apart the way you put it together, empty those coffee grounds and then you just rinse it with some hot water.
