Our current guest espresso & filter exclusively from .coffee & available at both locations

Espresso - Edinson Argote Castillo - Colombia - Washed with yeast inoculation - Castillo
Recently you can find a lot coffee under the name of Edinson Argote and Quebraditas. Quebraditas is a family-run project dedicated to producing premium coffee with standout and reproducible sensory profiles thanks to their fermentation processes, including thermal shock and yeast inoculation. They also focus on agronomic management and soil care (strategic shading, use of organic matter, maintenance of soil pH and calcium) that allows them to increase the potential of each crop. This coffee will give you sweet notes of pink marshmallow, vanilla and grapefruit. We do expect to be funky in espresso.

Filter - Aquiares Esperanza - Costa Rica - Natural, sundried anaerobically in a greenhouse - Esperanza
This coffee impressed us a lot when cupping. Aquiares is the gold standard for what a farm in Costa Rica can be. They take care of their employees and the environment, and their coffee is the best in country. This Esperanza is the best lot of the year. This coffee will give you fruity and sweet notes of strawberry milkshake and tayberry. What is tayberry? It is a hybrid by crossing red raspberry and blackberry.

Retail bags only
Bette Buna - Ethiopia - Kickstart natural - 74112, 74110, Wild Guji Megadu for GTS
Edinson Argote Peach Melba - Colombia - Peach Co-Fermented - Caturra for ECS
The former one with extra burst of sweetness alongside fruity-floral notes of cheey juice and coffee blossom while the later one with sweet notes of raspberry and vanilla tie it all together to create a bold Peach Melba experience you won’t soon forget.

Pat myself on the back day ……

Little celebration today for me as I installed, all by myself, a kitchen tap.

I love my plumber. He’s called but to get him out to do this is, well, expensive.

So I had a go myself.

As I was installing I got dripped on, then lots of water started coming out for no reason, then it stopped. Then I installed it.

And it works!!

Inside the mind of a coffee shop owner. Nice one.

Opening date August 14th 2009 - exactly the day we planned
Just turned 40 years old, never been a barista, but worked in hospitality since I was 17.
I was the manager, we had two baristas, 1 chef & 1 part timer on service.
Open Monday to Friday 7:30 to 6, Saturday from 9:00 to 6.

In October 2009, I went home to my wife who was 6 months pregnant with our first child to our one bedroom flat in Hackney, lay down on the bed next to her & started crying.
‘I can’t do this, it’s too hard…’
She said ‘you have to’

Back up at 5 am the next day ready for another 12 hour shift.
December 25th & 3 months rent is due.
I can’t afford it.
My landlord’s agent said ‘write me 3 cheques, I’ll bank them each month instead’.
January 2010 & Layla was born, on exactly the day she was planned. Australia Day.

I had £1500 left in the bank account.

In February 2010, we were awarded best Independent Coffee Shop in Europe.
From then on, that’s always been our goal, ‘to always be regarded as one of the best coffee shops in the UK by the industry, the media & the public.’

From February onwards, more people started coming, almost none of them knew what a flat white was. The bank balance became more stable. Our second year we grew 70% from the first.

17 years later we are still here. Much has changed, but much is still the same.
Joe with two locations, no plans to expand exponentially, no outside investment. Still proudly independent & still not a barista.

Thank you massively to everyone who has stepped over the threshold since then. The industry, the media & the public & amazingly, the employees who join this vision. It’s so much appreciated.

Thank you of course to my wife who said ‘you have to…’

Wishing all of you the very best, thank you again & if you ever want to talk about your dreams or your journey, come see me. It’s nice to talk.
Respect
Peter

Mate i'm tired.....

I need a coffee and something to help me win the battle.

Think I'll have an ANZAC biscuit....

ANZAC - Australia New Zealand Army Corp
The recipe for these biscuits are by the ladies back home during WW1 and made for the boys on the front.

Oats, golden syrup, coconut, butter & sugar.

We make them in our kitchens here every day.

Helping you win your battles, one biscuit at a time.

Legendary.

At Kaffeine, we focus on what is known here as ‘The 1%’s’ - the fine details.

It’s a management system I was taught over 25 years ago by a manager of a hotel in Melbourne.

It’s very easy to build the big percentages, but to be perfect you have to focus on the small details. This is what is hard.

So for example the espresso syrup on our pancakes is made tray with espresso from the coffee machine. It’s like having coffee, on your pancakes.

Amazing

Thank you Phillip for noticing.

Focaccia's are back!

Lunch time focaccias are back at Kaffeine.

When we opened 17 years ago, we started with focaccia from bakery, then we moved to baguettes, then to our own brioches & now we are back with the most delicious focaccia bread we know of.

Check our weekly changing menu online, or just come into store and get a focaccia lightly toasted on our grills for eat in or takeaway.

Lunch from 11:45 each day, available both locations.

The savoury scroll.

What is your favourite flavour?

On the menu for over 17 years, we change the ingredients every week.

This one in an OG flavour, courgette & feta.

Another favourite is the classic Vegemite & cheddar.

We think the key is toasting them on the grills.

Filling, slightly salty, absolutely delicious.

Available both locations.

We have been using since Novembver 2024 and we are very very happy.

In 2009, when we opened, we had an old school PC based till system and cash drawer, then around 2012 we were one of the first to start using an Ipad based POS system, then we moved to another POS supplier but this just did not work for us.

It took Square about 2 years to convince us to move to them. Moving is a big process, a big decision.

Square not only help us with POS, they are also very very much supportive of small businesses and are actively lobbying the Government to make things easier and promote growth in this industry.

After all, as with all suppliers, if the industry contracts and declines, so do they. And they have the power and influence to help.

Square POS - not a paid ad, just highly recommended

The famous Kaffeine banana bread.

I remember serving a lady who said 'can I have your amazing banana bread, toasted with butter on the side please?" and I said 'do you like peanut butter?' and she said 'yes I do' and I said 'would you like to add some to your banana bread?" and she said 'holy f... are you f...... serious?"

Probably one of the best reactions ever

Would you like the recipe?

Watch this space, recipes for our/your favourite Kaffeine baked products will be online soon.

In the meantime, come in and have some & elevate it even further by putting peanut better on yours.

What people say

Kaffeine, located on Eastcastle Street in London, is a coffee shop that has been open since March 2015. It is perfectly situated just one street back from Oxford Street, making it easily accessible for those looking for a great cup of coffee. The cafe boasts an impressive 3 group Cyncra machine that has been on the bar ever since they upgraded to it within two years of opening. This machine has produced countless cups of coffee and helped many baristas develop their craft.

Kaffeine's brunch menu is served until 2:45 pm each day and includes delicious options such as avocado on toast - a dish that has become a staple in many cafes but was originally made by the owner's mother over 40 years ago! The cafe prides itself on standing out from the crowd and being one of the leading cafes not only in London but also in the UK and Europe. Their mission statement is to always be regarded as one of the best cafes in the UK by the media.

Overall, Kaffeine is a must-visit coffee shop for anyone looking for exceptional coffee and delicious brunch options. With its prime location, impressive equipment, and dedication to excellence, it's no wonder why Kaffeine continues to stand out after 13 years in business.
