Coffee ☕

Where is the best coffee in London or Munich?

This is a coffee emergency.

This year I started making coffee at home a lot more than I have in the past, mainly due to investing in a new set up. Tried quite a lot of different roasters/beans which has been great. Have a few go to roasters now and a better idea of the beans/roasts I tend to prefer. Here's to 2024!

Focused more on speciality coffee, but still an interesting watch.

A few offers going round for father's day. Here's a couple I've come across so far and are both for 1kg bags.

• Rumble Coffee - KILOGRAMBEANS

Lead author Dr. Rajeev Roychand from RMIT University said the team developed a technique to make concrete 30% stronger by turning waste coffee grounds into biochar, using a low-energy process without oxygen at 350 degrees Celsius.

Australia generates 75 million kilograms of ground coffee waste every year-most of it goes to landfills.

Published in the Journal of Cleaner Production, the study by RMIT engineers is the first to prove that waste coffee grounds can be used to improve concrete.

"The inspiration for our work was to find an innovative way of using the large amounts of coffee waste in construction projects rather than going to landfills-to give coffee a 'double shot' at life," said Roychand, a Postdoctoral Research Fellow at RMIT. "Several councils that are battling with the disposal of organic waste have shown interest in our work."

"The concrete industry has the potential to contribute significantly to increasing the recycling of organic waste such as used coffee."

"Our research is in the early stages, but these exciting findings offer an innovative way to greatly reduce the amount of organic waste that goes to landfill."

"Our research team has gained extensive experience in developing highly optimized biochars from different organic wastes, including wood biochar, food-waste biochar, agricultural waste biochar, and municipal solid-waste biochar, for concrete applications," Saberian said.

CoffeeKii is a compostable plastic that recycles coffee grounds, developed by a team at the ANU Research School of Chemistry.

I know posting this sucks but the more you know. Better to know than not know.

Was wondering what people's coffee setups are.

I'll start. I mainly drink espresso and piccolo's. But also have several Moka pots that only get used once every few months since getting the BDB.

• Breville Dual Boiler
• Kingrinder K4

I don't have a microwave so I didn't pick this up to try it out. Was clean and seemed to have all the parts. Just like a stove top percolator, but only for microwaves.

I haven't been sleeping well so I've cut back on coffee the past few days to see if it helps. Remembered I had some roast dandy around for just such an occassion.

I'm roasting beans today and have just finished my first batch. I'm experimenting with single origin blends combining a few different roasting profiles. These are the lightest roast I will do, the next batch will be a darker roast, with a half quantity of an even darker roast. In theory this will give a more complex flavour profile.

I am still quite new to roasting and I am trying out different things to see what I like. I generally do plunger coffee not espresso, and find I prefer lighter roasts in general. Small changes in how you roast can make big differences in the outcome though - I have been focussing on cooling the beans quickly after roasting which made a noticable improvement in flavour.

... of your coffee or of your coffee being made

I've been gradually making my way through a variety of coffee beans over the last few months and was wondering what recommendations people here have for beans or roasters in Australia.

Thought it might also be helpful to anyone who was wanting to try something new but didn't know where to start.

Are you a fan of espresso, cold brew, aeropress? Do you try new beans and roasters regularly, or stay with what you know and love?

I generally prefer filter coffee (with a re-usable filter, no oil sucking paper!) or plunger, but currently have only the plunger because of lack of space. A good syphon can also be supurb. I've also started roasting my own beans - I'm definitely a long way from expert, but am getting pretty solid results and am am slowly improving.

Coffee has gone up everywhere over the last couple of years, to the point where a decent cup of coffee in Perth seems to average about $5.50 to $6.

Are there any holdouts left where you can get a good cup for under $5?

Let's make this the place to discuss anything coffee related, with an Australian perspective.
