3 Common Barista Mistakes

Posted by Jimmy Evans

There are certain things you shouldn't do or at least avoid doing when trying to make good consistent coffee. In this video Jimmy discusses 3 mistakes in particular which we find are most common when we walk into a cafe for the first time.

The first mistake is tapping your group handle with the tamp after you've just carefully distributed and tamped the coffee. Why shouldn't you do this? You shouldn't because you will crack and dislodge the puck from the handle which will cause extraction issues.

Second mistake is to leave left over milk laying around in milk jugs that has already been stretched only to top them up with fresh milk and stretch it all again. Not only is it a health concern but it's also going to make your coffee taste nasty.

The last mistake is leaving your group handles out of the machine between coffees where they will get cold. This will change the temperature of the water as it passes through the coffee puck and alter the flavour of the extraction to it's detriment.

when i walk into a cafe i see three

common mistakes baristas are making all

the time

stick around i'll tell you what they are

[Music]

hey guys i'm jimmy welcome back to the

artistic youtube channel where we talk

you through all things coffee

if you haven't already be sure to

subscribe to our channel uh like this

video and hit the bell icon so don't

miss out on any of our future videos

so today i want to talk to you about the

three common mistakes that i'm seeing

in so many cafes all around the place so

number one

i'm still seeing people tapping their

baskets with their

tamp now this is why you're doing it why

you're still doing it it's doing so much

damage not only physically to your tamp

trashing your tamp trashing your baskets

and your group heads

but the biggest issue that we see is

channeling so if you haven't learned

enough about channeling go and watch our

other video we'll put the link in

but what you're doing is you're damaging

all of the preparation work that you've

done

you're creating cracks through your park

you're separating your puck from the

edges and that's where the water is

going to run through as quickly as

possible

so you're going to reduce the your

extraction times you're going to reduce

the quality of your extraction

simply by tapping so you've got to stop

it so number two

you've really got to stop reheating milk

we all know what it's like when you go

into a cafe and you see a heap of milk

jugs and they've all got leftover milk

in them

basically they're sitting within what is

the australian food standard

of potentially between five and sixty

degrees of that

danger zone of temperature so bacteria

grows within that time so it's just

unsafe to have that

type of heated milk sitting on your

bench for starters get yourself a jug

rinse so you can reduce the amount of

milk

jugs that you even need watch our other

video we'll

link below which is about how to reduce

your wastage and get better at your milk

levels

because the biggest issue is just people

just don't want to waste milk but

you're it's detrimental to the flavor of

your coffee most of all

so when you heat milk the proteins

harden

the air particles stick to those

proteins and you can't replicate that

twice

same as the sugars the sugars will break

down into smaller sugars and they will

bring out some beautiful sweetness in

that milk

but again it's not going to happen twice

so every time you top up cold milk

on top of hot milk you're just reducing

the quality of the coffee that you're

serving

and we just don't want to do that and

lastly

the other thing i hate to see is this

it's leaving your group handles

out of your machine to get cold coffee

needs to

be extracted at the right temperature

and consistently the right temperature

to maintain the flavor that you really

want

so when you add water to your park if

you

have got cold handles you're going to

change the temperature that the water is

going through

and that's going to exchange your

extractions and therefore change your

flavor

i'm all for taking your heads out

cleaning them

flushing the machine and making sure

you're all prepared for next time

but just remember to put your grip

handles back up into your machine to

keep them

nice and hot so then my three pet hates

when i walk into a cafe

what are your pet hates put them in the

comments below we might make another

video

but we'd just love to hear uh people's

horror stories so um

if you haven't already be sure to

subscribe to our channel like this video

and hit the bell icon so you don't miss

out on any future videos

and i'll catch you next time thanks guys

cheers bye
