Ground coffee

Dont use boiling water you say? I got a taste for Vietnameee coffee and they use this wretched cylindrical collander which I can never get to work properly.

But I love Vietnameese Coffee and cant seem to make it myslf. I normally chuck the coffee in the billy and give it a swirl in boiling water and put up with a few grounds. But the taste is never any good.

Should I get a plunger and use it off the boil?

there was a thread on coffee on this forum and the information that is on it about coffee was very enlightening.

a couple of things I remember was 85 deg was the temp for coffee not boiling

coffee gives off co2 for 14 days after roasting then it reaches peak flavour

maybe some one could find a link

texta · Newbie

not correct . it depends on the bean . some coffee reaches its best long before 14 days and infact has already started to go down hill after that much time . then there are other coffee's monsooned coffee from india is one that comes to mind that will not be at its best until 3 weeks or so after roasting . the columbian that i am roasting is pretty dam good after 2 days post roast and is very good for 2 to 3 weeks then very slowly downgrade a little but still not to bad for a few more weeks . any older than that i dont know it never gets that far here but i do know that some people that buy beans from me get a lot longer but i think they keep it in the freezer.

I also roast my own Johno, have been for over 10 years, I use a Coretto, what method do you use?

I tend to agree with you re aging of beans, however one point I would make, once ground coffee starts to deteriorate immediately, within 12 hours it no longer suitable for espresso, OK for Frech press or similar, after 10 days its only use is for compost. smile

Ditto Kesa, been buying green beans from Andy for over 10 years, good quality, terrific range and great service.

I roast about 750 grams every 10 days, fresh roasted coffee as close as the back shed. smile

I've got to buy another probe off him , mines lost accuracy due to the wirie coming loose inside.... still , got 10 or so years out of it
Have you tried coffeesnobs.com.au/blending-room/29809-kjms-house-blend.html ?

Santa · Guru

Don't blend much Kesa, roast mainly single origin, sometimes with a percentage of robusta. smile

kesa32 · Senior Member

Go Santa ! Robusta gets the heart moving :)

On a side note , was helping out at the Salvo's through a work scheme last week , they actually had a commercial machine and grinder there and l made the workers there coffee's , only thing was the beans were use by next month , so l presume nearly a year old ...... they didn't mind the resulting brew , l gave it a miss lol :)

Emergency repairs for caffeine, as the 5 sided key in the handle wore loose & was on the verge of turning freely, panic set in!

I could have bought a new grinder & it would have been easier, but since I had nothing else better to do I fixed the old handle.

The 5 sided key was a pain in the neck to file to size, mostly with a needle file, but got there in the end. I had some 3 x 20 stainless 316 flat bar, so that won't rust.

Tapped two M4 holes for screws. Also used some Loctite. The small Bosch 10.8 v (12v) angle grinder is probably one of the best tools available.

Very happy with the result & we can continue to grind our beans.

Nice neat job Jon, well done, I agree an angle grinder is certainly a handy tool, the 12 volt Bosch looks good, will have to investigate.

I've got a couple of Makita battery operated tools, perhaps the also have a grinder.

Whenarewethere · Guru

I have got Makita tools, currently all 240v, they are good. Makita have a brilliant range of battery tools. All the builders use them. I have a Metabo 18v drill, it was great but I have jumped brands due to the range of products.

But I have bought a lot of the 10.8v Bosch Professional tools & they are so good. A 10.8v (12v) tool today is virtually as powerful as 18v from a decade ago, & I have a few 18v Bosch tool.

I can't rate the Bosch 10.8v angle grinder highly enough. It will cut the first 60 x 3 pipe in 2 minutes, so in other words, great for cutting locks! It does slow down as the motor heats up, but that is not the point of this tool. Short term quick & quiet. Also have 3 drills (2 hammer), their Dremel equivalent, brilliant, the tiny circular saw, also brilliant for the right task, impact driver & 3 LED lights which are not overly bright but I use them a lot.

Another great task for the grinder is cleaning up arch bars overhead. The light weight saves your arms, you can just keep going for an hour at a time.

Minimum battery I suggest is the 4.0Ah for the grinder, they now make a 6.0Ah. I have three 2.5Ah batteries as well & they are a bit small for the angle grinder but ok for the drill, these have been replaced with 3.0Ah version now, possibly still a bit small for the grinder.

Getting a bit off my original topic!

While on the subject of Coffee and Workshops .... this is my current project - a "cut down , hot rodded version" of a Boema Single Group Commercial espresso machine and converted from Manual to Touch Pad operation. This will be mounted in the side of our Fifth Wheeler in place of a LaPavoni Lever machine.

Wish we had the room being in a car only, so we have to go manual.

Nevertheless, the jealous looks in the outback are worth that alone!

gdayjr · Senior Member

WOW, i must be boring.

I use shop bought Vitoria ground coffe and an Aero Press.

No snobbery here, just simple coffee, i used to love the brewed coffee at Maccas, and i like the way the Americans servre their coffe, Bottomless.

Whenarewethere · Guru

A few times we have had to buy the same coffee pre ground as they sold out of beans. We were able to do side by side taste test & repeat over a number of days as we still had beans.

It is important to test over a number of days as, as much as one tries to get everything exactly the same you never get it quite right, & taste changes day to day.

Beans definitely taste better than pre ground.

& a reminder for everyone, NEVER use boiling water in any coffee inciuding instant coffee. If you like a hot coffee pre heat the cup.

We use a Able fine filter in the Aeropress. Have the standard filter as well.

KJB · Guru

My La Pavoni Lever machine in our Slide- on camper. Powered by a built in Honda EU20i Gen set.

I pre -grind a quantity of beans before leaving home (not ideal) . I hope to be able to install a Grinder in the Slide on in near future - I have made room for it.

This set up is quick and easy to use. (no unpacking etc.- just open the door!)

Never heard anything so ridiculous in my life, been boiling the kettle for a cup of coffee ever since Moses played full back for the Arabs.

No fancy grinders or pods, just plain old instant.

Whenarewethere is right, if you enjoy good coffee never use boiling water, the ideal temperature for espresso is approx 90°C.

If you drink instant, doesn't really matter much, the terms instant and coffee are contradictory. wink

Water boils at 100C, by the time you get it in the cup and a dash of milk pretty close to 90C, anyway don't drink Expresso too strong.

If I want a fancy cuppa, I'll go to a cafe, otherwise boil the billy

Coffee Head (incl. Group handle ..) and coffee water in a "Commercial" Espresso machine is regulated to around 90 - 92 Degrees C via a "heat exchanger" system . The boiler (a different system ) is for steam and boiling water.

Coffee is very susceptible to heat - boiling water burns it quickly to a bitter taste. It will only tolerate 90 Degree C water for no more than around 30 secs. before degrading and becoming bitter. That is why Baristas "pull" their "shot" (30mls single or 60mls double shot) in the 24 sec. to 30 sec. range and this timing is controlled by the grinder.(how fine or coarse the coffee is ).

Why do many hospital "baristas" use 70 degree then?

Probably because of Public Risk issues (spilling in bed etc..) Many Cafes etc. cut back on temp. for the same reason (I think this could be a reason to put people "off" coffee as it is not nice if half cold.) - that is why if I ever buy a coffee any where I always ask for "extra hot" but just watch they do not boil the milk when "stretching it" for a capuccino.

I'd be more concerned about keeping my cans of beer below 5C, love a coldie.

Morning KJB.

You seem to have a pretty fair knowledge re HX machines and espresso, I've owned one and used it daily for over 10 years, they really are an excellent way to make espresso, easy to use, very reliable and given regular routine maintenance will last for ages.

Do you own one or have you researched them.

This is the machine I use. smile

Cant argue with your reasoning Bob, it's all down to personal taste/preference. smile

Totally agree Craig, always have an esky when travelling for beer, make our own ice with takeaway containers that we use for frozen meals first.

Never had an Engel or Waeco fridge, about 4 different size eskies though.

This coffee thread is too serious for me, really only 2 cups per morning for me, white with two thanks.

Just investigating a new coffee machine, for our once a 3-4 week capuchino, most of them would require a new kitchen for us and a bank loan to boot.
DeLonghi or Sunbeam seem to fit our needs, small, do two cups, buy ground beans, and a small footprint. Around $200
But otherwise Moccano freeze dried no 5, 2 in the morning, now raw sugar and good milk A2 at the moment.

Hope Teague will not be in the Bucks quit school
