The FB80 holds 3.4 / 5 / 6.8 liters for 2 / 3 / 4 groups respectively.
I guess you’ll have to measure it. A couple minutes at most.
If your machines cool down overnight it’s less energy intensive. If not, use the hot water to mop a la @Mat_North !
Believe it or not, I’ve got a specific toothbrush that i dip in a little cup of batch brewed coffee and brush with before i start tasting. It really does a good job of clearing out the toothpaste flavors!
I think i should try this step
It’s little gems of informations like this that keep me coming back to the online forums.
I had never thought of purging all of the boilers water first thing - would explain a few issues we have in the mornings.
Running a few shots through the mythos and group heads is always a must for me to warm up the machines.
normaly in the morning…what i do is,flush grinder to clean out coffee beans from chamber (dont throw away the coffee ground),purge steam wand,a little bit brush on the shower screen and after that flush group head,flush water boiler,after done all this then i start to calibrate.using yesterday recipe and correct then flavour from there.
I come in to the shop, start brewing a pot of coffee, and start warming the ganache warmers. While those two things are going, I start the espresso process. In order to purge the boilers, the espresso grinders and season the group heads, I pull a shot through each group head while rinsing the screen before and after each shot. Now I’m ready to dial in, I do this by pulling a shot to yesterdays parameters and adjust from there, if needed. Once the espresso tastes good on its own, I taste the espresso in a capp, if it tastes good in a capp, then its ready to be served. I then count the register and set up the pastry case.
The most efficient way to open a shop is to have the things that are done automatically, started before you have to do the manual stuff; and that is why I start brewing the coffee and have the chocolate sauce melt while im dialing my espresso in.
My standard morning routine goes as follows
- Purge all water filters
- Turn on machines and purge their boilers completely
- Grind at least 100 grams through all grinders to start warming them up and to fill up the burr chamber
- Whilst purging the grinders and warming them up, I’ll put about a litre through each group to warm up the portafilters and get everything nice and toasty
- Start by dialing in all grinders to the previous days recipes, adjusting as needed. Grinders are repositioned to the very last setting of the previous day so usually only small adjustments are needed once the grinder has warmed up
- Double check all filters and batch brews are tasting delicious
- Tasting session with floor staff of all filters, espressos and milk based coffees on offer that day prior to open, and a sheet is filled out with recipes and tasting notes of each coffee at the same time
Good little tip I’ve picked up is to use rubber bands and tape to balance out the weight of all your portafilters in the morning before you start dialling in and after once all the handles have accumulated some oils as it tends to throw the weight off a little. Once you get into the habit of constantly evening out the weight of all your handles service becomes that much easier.
Lately we have been experimenting with using yesterdays leftover coffee to dial in and using a fresh bag of beans to dial in.
They behave differently I my opinion.
Yesterdays bean runs fast initially but a fresh bag gets flow rate comparable to yesterdays faster.
Speaking with our roaster we hypothesize that the old bean has dried out and is more brittle.
I bring this up because i was wondering if anyone has experimented with the above practice to purging the boilers and filters?
For the 4 group, that is over 2 boilers, so I assume that a purge of 3.4 litres per boiler meaning 3.4 litres from the 2 left groups and 3.4 litres from the 2 right groups. Of course, please correct me if I am wrong.
Do you purge the steam boiler using the hot water tap?
Roughly how much coffee (waste/dialling in/taste) is used prior to service?
