The drum is durable since it has a 2mm stainless steel body. To make it perfect for the job. Ensuring proper coffee stirring are two stirring blades. They ensure coffee beans are evenly turned to enable complete roasting. 

Apart from the even roasting, the machine has a bimetallic thermometer that can measure up to 300°C. A hopper and sampler also ensure this machine is super easy and convenient.options

Despite these fantastic features, the machine has no timer and requires a gas burner to roast. 

Roasting Capacity 4/5 

On roasting capacity, Kaldi Mini coffee roaster is not for large quantities. It can only roast 200-250g of beans. 

This capacity means it can take some time if you want to roast a lot of coffee beans. This is even more complicated since it isn’t an automatic machine. 

If you want a large machine with more roasting capacity, there are options like the Kaldi New Wide 400 Upgraded Version

Roasting Time 4.5/5 

The roasting time is impressive when using the Kaldi mini roaster. It has an efficient tilted drum and provides fast coffee roasting. 

While it can roast up to 250 grams, you can opt for small batches to achieve the perfect roast quickly. Typically, the machine will take 8-20 minutes to attain dark roast. 

When roasting about 150 grams, the machine will take an average of 15 minutes. However, the time will also depend on the roasting temperatures. 

Roast Quality 5/5

One of the factors that affect the roast quality is the drum. This machine has a thick stainless-steel drum, which means it is more efficient. 

It provides slow heating to produce excellent roast during the roasting process. 

Since the drum is stainless steel and has double stirrers, the beans get perfect roasting. 

Even though it lacks an inbuilt timer, you can control temperature and time to achieve light, medium, or dark roast. 

However, you need to get a chaff remover since this roaster doesn’t have the mechanism.

Cleaning 4.8/5

Cleaning your machine is vital to ensure the quality of coffee is as per your expectations. Kaldi mini roaster has stainless steel, which is super simple to clean. 

Cleaning is simple; rubbing the drum with a cloth is enough. Also, the casing is simple to wipe clean without the need to use water. This machine is easy to clean due to premium stainless steel. 

Price 4/5

In my opinion, the price is fantastic. The quality of this machine and its performance ensure the best experience when using it.  Also, shipping and after sale services  are   remarkable.  

The roaster doesn’t have other essentials like a gas stove and canister. Therefore, the overall cost for the complete setup exceeds the one listed. 

Don’t buy Kaldi Mini Coffee Roaster if

You love roasting coffee outdoors. 

This is not the best roaster for anyone who loves roasting coffee outdoors. It doesn’t have wind guards, affecting the performance due to flame deflection by the wind. 

Also, since it doesn’t have a smoke suppressor, you need to roast coffee in a chimney. 

You want a complete gas coffee roaster. 

If you are looking for a gas coffee roaster, this doesn’t come with a gas canister. The gas is bought separately, which means spending more money. 

Especially if you don’t have a gas stove, you need to invest in a stove. 

Is Kaldi Mini Coffee Roaster a Recommendable Option? 

Kaldi mini coffee roaster is a perfectly recommendable machine. Especially if you have a gas roaster, it’s a fantastic replacement. The heavy-duty construction ensures there is exceptional roasting due to even heat distribution. 

On the other hand, the initial cost will be a bit costly if you don’t have the necessary accessories like gas stoves.

Will this machine work with a gas cooktop?
The roaster will perfectly work with your gas cooktop. However, you need an open place since it doesn’t have a smoke suppressor. 
Does coffee roast affect caffeine?
The roasting of coffee doesn’t have much effect on caffeine levels. Roasting only improves the coffee flavor due to smoke and the change of state of the beans.
Can you roast good coffee at home?
Roasting a good coffee at home is possible. Whether you are a beginner or expert, you only need a good roaster and instructions.
