Coffee capsules

The Consumer guide to coffee capsules and capsule waste.

Espresso with coffee capsules

If you're looking for the perfect café style espresso, coffee capsules could be your answer.

How they work

Coffee capsule machines don’t have a portafilter or require tamping. Instead they use pre-packaged coffee capsules. These capsules are hermetically sealed, giving them a long shelf life compared to beans or grind. When a capsule is inserted into the machine and extraction starts, the capsule is pierced and water is pumped through and then poured into the cup.

The same process is used for milk capsules.

Capsule brands

Capsule espresso machines work best with that brand’s capsule. This means choosing a machine that uses coffee capsules you like. Try out the flavours before you buy. Some stores offer taste tests or if you have friends with a capsule machine, invite yourself over for a coffee. Here’s our summary of the major brands available.

They have six capsule ranges available, including George Clooney’s favourite Decaffeinato Intenso. Each range comes in four or more strengths. They also have a Variations range that blend flavours such as caramel and vanilla with the coffee. Nespresso capsules are sold at five stores and online.

Nescafe Dolce Gusto
Nescafe have 11 flavours from macchiato to Americano, one tea flavour and two hot chocolates. Capsules are available in supermarkets and selected appliance retailers. For some flavours, Nescafe also include milk capsules (used like coffee capsules). However, this results in extra waste.

Sold in Countdown stores under the Select brand, these capsules come in four strengths – standard, medium roast, smooth and decaffeinated. Other businesses, such as Gloria Jean’s and Moccona, also produce Caffitaly capsules with their own grind blends.

Other brands
No manufacturer recommends using third-party capsules in its machines, but that doesn’t mean they won’t work in them. “Compatible” capsules are readily available in supermarkets, but using them could potentially void your warranty. Your CGA rights would only be affected if they caused a fault.

There are compostable capsules on the market. There are also refillable coffee capsules you can prepare yourself – although this does take away from the convenience of a capsule machine.

Capsule waste

Why is recycling used coffee capsules so difficult? Because they’re made of different materials that can vary from brand to brand. Some are entirely aluminium or plastic, while others are a mixture. None are marked with a plastic recycling number, which means they can’t be thrown out with your household recycling.

19june capsule waste

We emptied coffee capsules from three major brands and weighed them. Nespresso (aluminium) capsules weighed 1g on average, while Nescafe Dolce Gusto (aluminium and plastic) and Caffitaly (plastic) capsules were just over 3g each.

Most brands have their own programmes or support third-party companies in collecting and recycling capsules. TerraCycle collects Nescafe Dolce Gusto and L’OR capsules. Nespresso capsules can be returned to Nespresso for recycling. You can’t recycle Caffitaly capsules.

How many capsules have actually been recycled in New Zealand is uncertain.

Manufacturers, in choosing to use capsules to deliver coffee, are responsible for generating this waste and must take an active role in helping consumers recycle them.

Capsule waste survey

Our 2018 survey of 94 capsule coffee drinkers found 58% recycled their capsules. However, 30% didn’t know they could recycle capsules.

stainless coffee cups

I recently discovered we could buy re-useable coffee cups in stainless steel which we would top up with our own coffee. It may not be as convenient but is definitely more enviro-friendly. It would be great to read a review of how well they perform compared to a plunger or stove brew.

Coffee capsules

I consider that the lack of responsibility shown by the manufacturers of coffee capsules far outweighs any "convenience" that they offer. They should be outlawed along with single-use plastics!
I was disappointed that you had not pointed out the waste issue more emphatically in the review of coffee machines.

Countdown no longer stock capsules for the Caffitlay machines. They still have the machines on the shelf for $138.00
Briscoes used to stock capsules for Caffitaly but they no longer sell them.
This leaves just one stockist located in Mt Eden, Auckland.
