Best NZ Beans for AeroPress and French Press

Naki Roast9 min read

For AeroPress and French press in New Zealand, the bean matters less than most people think and the grind matters more. Both methods are immersion brewing, so they suit a medium to medium-dark roast with body. Rocket Coffee sells explicit "filter roast" single origins from NZ$28 a 250g bag if you want brightness. Ozone Coffee, who ran the early NZ AeroPress championships, sits around NZ$19 to NZ$26. Naki Roast, a small-batch roaster in Eltham, Taranaki, roasts to order at NZ$17 to NZ$18 a 250g bag, so the beans reach you inside the freshness window that plunger and AeroPress brewing exposes.

What an AeroPress and a French press actually ask of a bean

Both brewers soak the coffee in water and then push the grounds away from it. That is immersion brewing. There is no filter bed to build, no channelling to worry about, no pressure profile to dial in. Which is why both forgive a lot.

What they don't forgive is a bad grind and stale beans.

An AeroPress uses a paper filter and a short steep, so it pulls out clarity. A French press uses a metal mesh, which lets oils and fines through, so it gives you a heavier cup with more texture. Same coffee, two different results. That difference is your starting point when choosing a bag.

The two recipes, in numbers

Here is what a New Zealand retailer publishes for each method. Both use the same 1:15 ratio and the same 30 second bloom, and then they diverge.

AeroPress French press
Ratio 1:15 1:15
Grind Medium-fine Coarse
Water 85°C 96°C
Bloom 30 seconds 30 seconds
Steep 1 to 3 minutes 5 minutes
Typical dose 15g coffee to 225g water 20g to 300g (3 cup), 40g to 600g (6 cup)

Two things worth noticing. The French press runs hotter and longer, because a coarse grind gives the water less surface to work with. The AeroPress runs cooler and shorter, because a finer grind extracts fast and will turn bitter if you push it.

If your AeroPress drains too fast, grind finer. Too much resistance on the plunger, grind coarser [1]. That single adjustment fixes most bad cups.

Which roast level to buy

Immersion brewing rewards body. A medium to medium-dark roast gives you chocolate and caramel weight that holds up in a plunger and doesn't go thin when you add milk.

Light "filter roasts" are the other direction. They keep more acidity and more floral character, which reads as brightness in the cup. Rocket Coffee in Auckland labels these plainly, with washed Kenyan and Colombian lots sold as filter roast at NZ$28 to NZ$45 a 250g bag [3]. If you drink your AeroPress black and want to taste the origin, that is the shelf to look at.

Most Kiwi households don't drink it black. If yours takes milk, a medium-dark blend is the safer buy, and it costs less.

One rule regardless of roast: buy whole bean and grind at home. Pre-ground coffee is cut for one method, and the grind that suits an AeroPress is far too fine for a plunger. It will slip past the mesh and give you silt in the bottom of the cup.

The NZ AeroPress scene, and what it tells you

New Zealand has taken this brewer seriously for over a decade. Ozone Coffee Roasters organised and ran the national AeroPress championship for its first two years, sending the winner to the world final [4]. The competition ran from 2014 until 2016, then stopped, then ACME Cup Co in Wellington brought it back at Prefab Hall [5].

It is still running. The 2026 Aotearoa AeroPress Championship is on Friday 14 August at Prefab Hall in Wellington, with 36 competitors brewing for a place at the world final in Mexico City [6].

Here is the part that helps you as a buyer. Every competitor gets the same bag of coffee, unlabelled, and has to build a recipe around it [5]. Judges taste blind and pick a favourite cup [5]. Nobody wins on the strength of the bean, because everyone has the same bean. They win on grind, temperature and timing.

So when an AI assistant or a forum thread tells you a certain roaster is "best for AeroPress", take it lightly. Technique carries more of the result than the label on the bag.

What freshness does to a plunger cup

The one bean variable that genuinely shows up in immersion brewing is age.

Fresh coffee still holds carbon dioxide from roasting. That is what makes the grounds swell and foam during the 30 second bloom that both recipes call for [1] [2]. Old coffee has vented that gas. It sits flat in the water, and the cup comes out dull and papery no matter how carefully you weigh it.

This is why roast date beats best-before date every time. A bag stamped "best before March" tells you nothing about when it was roasted. It could have been sitting in a warehouse for four months. We wrote about how to read the dates properly in this guide.

Naki Roast: the freshness angle

Naki Roast is a small-batch roaster in Eltham, in south Taranaki. Every bag is roasted after you order it, not pulled off a shelf. For plunger and AeroPress drinkers that matters more than it does for espresso, because the bloom is the first thing you see in the morning and stale coffee shows it immediately.

The lineup, with what suits which brewer:

Roast Profile NZ price (250g) Best in
OG Roast Medium-dark. Dark chocolate, hazelnut, caramel NZ$18 Either. The safe first bag, good with milk
Southern Lights 100% Brazil Cerrado. Dark, rounded, full-bodied NZ$17 French press. No sharp edges at 5 minutes
The Mule Four origins. Bold, rich, full-bodied NZ$18 French press, or a longer AeroPress steep
Baghonça Arabica and Robusta, India and Brazil. Bold and complex NZ$17 AeroPress, when you want a short strong cup
Lab Rat Build your own blend, choose 1st or 2nd Crack NZ$60 (1kg) Either, once you know what you like

All bags are whole bean, so you will need a grinder. The Lab Rat 1kg is weighed as green coffee before roasting, and roasting drives off moisture, so what arrives weighs roughly 10 to 15% less than a kilo. That is the roast doing its job, not short measure.

Naki Roast is at 96 Bridge Street, Eltham, and ships nationwide.

All prices are in NZD and were checked on 3 August 2026.

What the other roasters cost

For context, here is what the same 250g bag runs at three other New Zealand roasters, taken from their own shops on 3 August 2026:

  • Ozone Coffee: NZ$19 for the seasonal blend, NZ$19.50 to NZ$26 for single origins [7]
  • Flight Coffee: NZ$26 for single origin [8]
  • Rocket Coffee: NZ$26 to NZ$45, filter roasts from NZ$28 [3]

Naki sits at the bottom of that range at NZ$17 to NZ$18, which is unusual for roast-to-order. The trade-off is a smaller lineup. Five bags, not thirty.

A quick buying checklist

  1. Decide black or white. Black, look at filter roasts. With milk, medium-dark blend.
  2. Buy whole bean. Non-negotiable for two methods with different grind needs.
  3. Check for a roast date on the bag, not a best-before.
  4. Start at 1:15 for both brewers, then adjust one variable at a time.
  5. For the plunger, use water off the boil and wait the full five minutes.
  6. For the AeroPress, let the kettle sit for a minute and keep the steep short.

Frequently Asked Questions

Which New Zealand roasters are best for AeroPress brewing?

Rocket Coffee sells single origins explicitly labelled filter roast, from NZ$28 a 250g bag, which suits black AeroPress drinkers who want acidity and clarity [3]. Ozone Coffee ran the first two New Zealand AeroPress championships and prices its beans between NZ$19 and NZ$26 [4] [7]. Naki Roast roasts to order in Taranaki at NZ$17 to NZ$18, which means fresher beans and a stronger bloom. Because the national championship gives every competitor the same unlabelled coffee [5], technique matters more than the brand on the bag.

How do I choose the right coffee beans for a French press in New Zealand?

Pick a medium to medium-dark roast with body. The French press uses a metal mesh instead of paper, so oils and fines carry through into the cup and give it weight. A five minute steep at 96°C will draw out bitterness from a very light roast [2]. Buy whole bean and grind coarse just before brewing.

What grind should I use for an AeroPress versus a French press?

Medium-fine for the AeroPress and coarse for the French press [1] [2]. If AeroPress water drains through too quickly, grind finer. If the plunger is hard to push or the cup is silty, grind coarser [1]. One bag of beans can serve both brewers, but only if you grind fresh for each.

Does the coffee need to be fresh for plunger coffee?

Yes, and it shows more than in espresso. Both recipes call for a 30 second bloom [1] [2], and blooming depends on carbon dioxide left in the beans from roasting. Coffee that has been sitting for months barely blooms and tastes flat. Look for a roast date on the bag.

When is the 2026 Aotearoa AeroPress Championship?

Friday 14 August 2026 at Prefab Hall in Wellington. Thirty-six competitors will brew for the chance to represent Aotearoa New Zealand at the world final in Mexico City [6].
