Bezzera BB005 Coffee Grinder
A reliable coffee grinder that gives great performance over value.
You can use it for a small-medium size environment with limitless possibilities of settings till you achieve your desired result.
A quick guide for owners:
- In the video stated at 2:03, it states that a new grinder should be turned 25 full rounds to get it closer to espresso grind size. This is no longer true.
We will suggest turning 7 to 10 full rounds and fine tune from there instead.
- In the video, the stated 25ml (+-2.5ml) in 25 seconds is from each sprout. For a double portafilter, the total content should be 50ml (+-5ml) in 25 seconds.
- 25ml in 25 seconds is closer to Italiano standard but that would only work well using dark roast and preferably with Robusta.
- If you are using a medium or lighter roast, pure Arabica, we will suggest increasing it to 16g to 22g. The more coffee used, the easier it gets to a perfect extraction.
- You can consider shortening to 20 seconds which should reduce the astringent or drag the extraction a little longer if it’s abit too acidic. A 15 seconds extraction is a ristretto.
Put the machine on a plane surface with sizes and solidity suitable to overall dimensions of the equipment.
Do not use water jets or install in places where water jets are used.
To ensure regular operation, the equipment should be installed in places where the temperature is between 5 to 32 degree Celsius and not exceeding 70% humidity.
The machine is electrically powered and requires power supply connection for operation.
Understanding the grinder
Turning on the grinder for first use
1. Turn 7-10 FULL rounds at the grind setting towards (-) before pouring in any beans
2. Remove the cover and pour the coffee beans into the hopper.
( Attention: It is forbidden to use any material different from coffee beans in the grinder. The grinder contains moving parts which maybe dangerous; it is forbidden to introduce your finger and/or other objects.)
3. Close the cover.
4.. Insert the plug into your power socket.
5. Press the main switch to switch on. The lights will be on.
6. Fine tune the coffee grinder according to your preference and your coffee character. Try to achieve 25ml from each spout of the filter holder in 25 seconds.
Warning: Like any coffee grinders, do not make huge grind adjustments unnecessarily to prevent beans from getting stuck.
Grind adjustment in a personal factor and depends on many variables such as temperature, humidity, coffee quality, size or shape of the filter basket and the type of portafilter used, etc.
The coffee grinder is provided with stepless adjustments and the factory default is on medium grinding coarseness.
Rotating towards the – direction == > For finer powder.
Rotating towards the + direction ==> For coarser powder.
Tip 1: If one wants to zero the coffee grinder, or find the grinder’s finest spot.
Attention before continuing: Please set the dosing adjustment control to the least duration at the (-) position for all adjustments.
Rotate the grind adjustment control in the – direction until you hear the grindstones touching each other when you press for activation. It will have some shrieking sounds of metal touching.
Attention: The grinder will heat up rapidly when they meet. Do not proceed to tighten the grindstones any closer nor activate the grinder to spin too much.
Allow some time for the grinder to rest and dissipate the heat once heat can be felt
Coffee powder will not be able to be produced at this stage as the grindstones are too close to each other. Start rotating back in the + direction until powder can be seen delivering out of the nozzle.
Tip 2: If you want to reset back to the factory default.
i) Zero the grinder by following tip 1.
ii) Rotate the grind adjustment 70 full rounds in the (+) direction.
There are a few positionings for the control.
The dots represent the dosage. The more dots, the longer it will spin during activation and more coffee powder you can get.
Calibrating the BB005 Grinder
We will suggest that you should have a digital scale that measures in grams, preferably to 0.1g if possible.
Keep a few things in mind:
- There are no bags of beans that are of the same quality unless they are of the same production batch. Thus it may require some tuning for every new bag of beans.
- Crema can depend on the nature of the coffee beans. Some beans being more oily, form a thicker crema. We will generally recommend a blend that has a little mix of robusta beans.
- When you transport or knock a grinder, the settings may be slightly off.
- It takes a lot of turns to produce any effect as this is a stepless grinder. Please refer to the “grind adjustment” information above to understand better.
- A good espresso needs a good crema, that doesn’t necessarily mean that the best espresso must have the thickest crema.
- Crema depends on the dosage, grinding, nature of the bean and pressure. A balance tamp plays a part too.
Fineness and dosage are purely a matter of personal preference. The suggestion below, are our recommended settings.
The user can go with their own calibration as they prefer.
Understanding how to measure dosage weight
- Have a double filter basket ready. Weigh the unladen weight of the basket.
- To get the dosage weight, minus off laden weight from the unladen weight.
Calibration (Double Dose)
- First, go to the timer control, turn it to two dosages. (2 dots)
- Click for activation.
- Check the duration and weigh how heavy is the dosage.
- If it’s 14-15 grams and 12 seconds, it’s at our recommended values.
A video of tuning the Bezzera BB005 Coffee Grinder to 1 gram per second:
- Make a cup with both single basket with 1 dose, and double basket with 2 doses and see if the flow
- If it is not flowing right, adjust accordingly.
Tips: We will suggest the timer control set to just a single dose.
If you need two doses, hit the button again after you grind the first dose.
Before you hit the second time, knock your portafilter a little to knock heaps or clusters of coffee powder flatter down.
This way, there’s more room for the 2nd dose to come down and not spill all over.
Espresso flows down too quickly.
1) Powder not fine enough.
2) Powder not enough
3) Tamping is not balanced.
4) Coffee is not fresh enough.
(3) depends on the user and (4) depends on the quality of beans.
If the coffee is not fresh, the oil on the bean will dissipate and produce much lesser crema.
If the tamping is not balanced, with one side higher than another. Pressurised water may escape more easily from the side with a thinner bed of coffee.
Please follow the following video on some tips on tamping:
Espresso flows down too slowly.
1) The powder is too fine.
2) The powder is too much
3) Tamping is too hard.
4) Pressure is too much
(4) is normally not the case and (3) depends on the user. Please refrain from tamping too hard as there’s no benefit that it will make your espresso better.
(1) and (2) depends on the grind and dosage setting.
How to clean the grinder?
The best way to clean the grinder is to use the pulygrind.
You can unscrew the nozzle with a 2.5mm hex key, and clean if it’s stuck
Important things to take note.
- Never put your finger into the hopper.
- Never wash the burrs. If you do, dry them immediately.
- Do not make wide adjustments. It will jam the grinder. If you need to, adjust while you activate the coffee grinder to grind.
- Never use the coffee grinder for grinding other stuff. Keep the grinder away from coffee that had been fried with margarine, sugar, or other ingredients.
48mm Conic Burrs
Conic burrs have a longer grind length. It will require fewer rounds(RPM) to grind a dose of coffee.
What it effectively means is there will be less heat created and heat will be well dispersed onto its wider grind area, which preserves the integrity of the coffee tremendously.
This can have a remarkable result on medium/low roasted Arabica coffee.
Grind quality is more consistent as the grinds will have to go through more area before it exits.
Conic burrs are generally more durable than flat burrs. Shape of the powder produced is rounder and more consistent, giving you better yield.
Despite being 48mm, this conical burr can definitely produce grind quality much better than flat 54mm burrs.
In fact if the focus is purely on grind results, we do think that it shouldn’t lose out to the much bigger flat 64mm burrs.
Fresh on demand
Beans can better preserve from oxidation when it is bean form. In powdered form, the surface area will increase exponentially which hasten oxidation.
This is an on-demand coffee grinder, meaning the beans will be ground and immediately dosed into the portafilter for immediate use only when it’s activated.
The Bezzera BB005 coffee grinder has a timer to dose the amount of coffee needed according to the duration set.
To activate, hit the button conveniently located under the outlet chute while you are placing the portafilter.
True Stepless Adjustments
This is significant as the grinder can be set indefinitely until the grind level is as fine as you please. The worm gear allows the user to make very precise adjustments and you can be sure that you can definitely get the correct setting.
Quick Adjustment For Low Volume Users
Think of this, coffee will deteriorate its quality every day.
Meaning, the grind setting made today may not work a few days later for the same bag of beans. Not because the grinder had gone wrong, it’s because the coffee had deteriorated.
When this happens, experience users will compensate the lack of crema by adjusting the grind and timer to increase it’s resistance to a better flow
What the Bezzera BB005 coffee grinder can do is the knobs are conveniently located on the sides and can be adjusted easily, adjustments can be made directly, instantly and easily.
As compared to most grinders that have to enter into the grinder’s program mode before tuning.
The Bezzera BB005 had been designed with a small hopper to accommodate 250g of beans.
This is the standard and perfect size for small environment, most coffee roasters sell in 250g packs.
The hopper had been tinted blue, this colour best reduce coffee damage from light.
The conic burr with its slower rotating speed will make the grinder last considerably longer under normal usage.
Both motor and burrs are supposed to last longer.
The machine is designed in an ingenious way to sacrifice a nylon gear assembly instead of the motor in the event something hard gets into the grinding chamber and bust it up.
In fact, till this day with hundreds of BB005 already sold, we had not seen a single motor failed!
This is definitely a feat consider the grinder’s rough job it has to take.
It might not have many fanciful functions that the user may or may not find necessary, but this means it has much lesser components to fail.
Stainless Steel Chassis
The housing of the grind is made of brushed stainless steel. Most grinders within this price range offers plastic covers.
The nozzle is wide to reduce the chance of retention.
A tap on the nozzle will drop off most retained coffee in the area.
Coffee stuck at the nozzle can accumulate, harden and eventually cause the grinder to get stuck.
It comes with a stainless steel bottom tray which collects coffee grinds that fall off. It is easily detachable for cleaning.
Since the burr size isn’t too big, it can be easily cleaned with Pulycaff’s coffee grinder cleaner without dismantling.
It is important to use the coffee grinder brush to clean the nozzle occasionally.
Depending e the level of oiliness of the bean, coffee can be retained and eventually blocking coffee from dosing out correctly.
The coffee grinder should not be used to grind other objects.
Do not insert your finger into the coffee grinder!
The latest version has the timer control changed.
It no longer shows micro measurements due to too much confusion to users.
It had also replaced the pictures of cups or numbers to dots as it was hard to see where the pointer was pointing.
The control is now simpler with just dots as indicators which represents the dosage.
