Modding the Classic is something that has gone on for many years by Gaggia enthusiasts. You may have seen Rancillio Silvia steam wand fitted to the pre-2015 models. This was quite common. This, of course, is no longer necessary as the 2019 Classic has the professional steam wand as standard.

OPV
Another common adjustment, rather than a modification, that users carried out on the pre-2015 model was the adjusting of the Over Pressure Valve. On the 2019 model the
OPV is on the top of the pump rather than being fitted to the boiler. It is not as easy as the older model. It seems to be a question a lot of enthusiasts seem to ask. I find that enthusiasts somehow find a way of adjusting things on the Classic. As a manufacturer's agent we need to warn against any internal adjustments or modifications as this will invalidate the manufacturer's warranty. The machine's default pressure for opening the solenoid is 9 bar. This is what the factory setting is. This is what you have even on professional machines. It is therefore not necessary to change this unless you want to perform unusual trials . Yes, it can have an impact on achieving different results on coffees depending on the fineness of the grind. I personally am happy changing the grind or the pressure I apply when tamping the coffee or increasing or decreasing the amount of coffee you put in to try out different tastes in coffee. Pre-infusing the coffee also can help.
 
PID
Another modification I see done is, fitting a PID controller. This is probably a good thing as it keeps the temperature range at a smaller range – say 85 -90 degrees, rather than the normal of 72 – 92 degrees. Fitting a PID is not something that you can easily do at home. Any modification can invalidate the warranty on the machine.

Simple Modifications
There are some simple modifications which can make a big difference to the quality of coffee. Two of these simple modifications are fitting a filter seal for the brew head and a professional shower disc. We now have a E61 silicone seal [blue] and a professional shower disc on our website. They are £5 each and they are both excellent. What it does is that it gives a bit more flexibility when you are fitting the portafilter on to the machine. It is easier to fit. You can put 18-19g of coffee in a 16g basket and still manage  to fit  the portafilter with relative ease  because the silicone seal is springy and flexible.

The pro shower disc has 2 layers – a metal layer with larger holes and a mesh layer. This allows the water to flow in a more controlled way from the brewhead.

Both items are available to buy on this website. If you need further advice, why not come and see us live and talk to us on Zoom. 

How do I get a good milk froth on a Gaggia Classic 2019 Pro?
​
It is a question I get asked many times. I think some of you are finding it harder than the previous models of the Classic which had the pannerello frothers. The Pannerello Frothers have a simple sleeve that allow air to always go into the milk, when you insert it into the jug. As you probably know, that air is main ingredient in stretching the milk. If you are a person who wants a flat white or a more controlled micro foaming, then the sleeve on a pannerello frother [the one you find on all the other models we do] can be a non starter. I usually take the sleeve off [on a panneello frother]  and foam the milk using, just the tip of the wand and get great results. When you do this, you will find that 'you' have to add the air. This will come with practice. I tend to put the tip of the wand [without the sleeve] about an inch into the milk and open the wand fully by rotating the knob fully.  The force of the steam will create a depression and a vortex in the milk and the milk should start to go round.

The Classic 2019 has the professional steam wand. This means that there is no air added by the frother. It just has the 2 holes on the nipple of the wand and therefore you have to control the air intake. It is therefore similar to foaming without the sleeve on a pannerello frother. If you use the right jug and practice a bit with the directing of the tip and adding of air, you can produce some great results. When I say, using the right jug, I think a lot of users who are used to the pannerello frother find it difficult to change to the Classic 2019 wand because they are trying to use the same jug that they had before and doing it the same way as before.

Tips

1. I wait till the the steam temperature is reached before starting. However, I always make sure that the the machine has been primed before use. If you do not have the right pressure in the boiler, you are going to struggle to get the steam build up.
2. ​Make sure you purge the wand to get some of the condensation of water out.
3. insert the tip into the milk, about an inch under the surface.
4. Open the knob fully quickly to a get a blast of steam into the milk, to create a vortex and keep it in if you want the milk to be creamy but not frothy. If you want it to be frothy, you need to carefully lower the jug to add more air almost below the surface of the milk.

​​
​Milk Jugs
Remember, different jugs can give different results. I quite like the straight jugs that we do, as they keep the swirling and gives more control by pushing the milk to the bottom. If you are using a V shaped jug, you will find a different result. There are obviously different sizes available. If you are wanting milk for a one or two cups, the 12oz [350cc] jug is ideal. Once you get used to this, you should be able to get a good micro foamed milk for flat white and latte art. If you add more air you can stretch it to about double the quantity in the jug. If you want a better pour for latte art, then have a look at the Motta Jugs.

Coffee is one of the most consumed drinks in the world. For break times or for an energy boost, it is a perfect companion for many moments throughout the day. And, once you have enjoyed its taste, do not throw away the coffee pucks! There are plenty of ways to give them a second life. For example, they can be recycled and used for gardening.
Coffee grounds, in fact, are rich in nutrients such as calcium, nitrogen, potassium and magnesium, essential for fertilisation. For this reason, they can be employed as an excellent natural compost, especially for plants that love acidic soils, such as azaleas, hydrangeas, rhododendrons and camellias. Before their reuse, it is important to store them properly in a dry plastic bag or sealed glass container, to prevent any mold formation. - reproduced from Gaggia Website www.gaggia.com/un-espresso-in-giardino-come-riciclare-i-fondi-di-caffe/

​So, how to use them, in the best way? Just spread the coffee directly on the ground or in the pot, near the plant. Furthermore, to make a powerful and ecological liquid solution, you can put two cups of coffee grounds in a bucket full of water, and let them sit there for at least 24 hours. The fertiliser obtained can be sprayed directly on the plants, as nourishment for the leaves, which will become greener and luxuriant.
Recycling coffee grounds can also be useful for another important ally for a healthy garden: the repellent. In fact, they can be scattered around the plants and at the edges of the garden. In this way, you can obtain a valid help in removing unwanted snails, insects and small animals. As an old grandmother’s remedy teaches, coffee grounds and ash are the perfect method to protect the garden, without resorting to chemicals or pesticides.
Moreover, not everyone knows that coffee grounds also favor the growth of many vegetables and fruits, such as carrots and radishes. The addition of coffee powder to the seeds of these veggies makes sowing easier and, during the development of the seedlings, it will release the right nourishment by keeping pests away.
Recycling is a precious and fundamental habit for the sustainability of the environment. Start with a small step: preserve your espresso coffee puck and give your favorite drink a “green” second life!
