The Giesen W1A, W1M and the W1E are perfectly suited for small roasts. That’s why our W1 series are often used for test roasting or trying to identify the perfect roast profile in a small batch, which then can be applied to larger batches.


It’s all in the name. Our W1 series is available in three types W1A, W1M and W1E. Commercial roasters designed to deliver consistent roasts, lower emissions and the lowest operating costs. The difference between the different types is that ‘A’ stands for automatic control, ‘M’ stands for manual control and ‘E’ stands for electric. All three roasters are fully customisable.

Presentation is key. That’s why we designed a beautiful presentation table to make your W1 stand out. The table is optional in our W1 series and fully customisable. Lots of design options are available like; pick your colour, select a table-top, or add your own design at the side of your table.


To reduce emission, operating costs and roast eco-friendly with the W1A & W1M, we offer a SFE filter in the table to reduce smoke and fine dust with 90%. The absorption of smoke also reduces the odour during roasting. Read more about our solutions to roast environmentally friendly and energy efficient on our roasting equipment page.

If you want to roast indoors without gas, our W1E is a good option for you. Our W1E is an electric coffee roaster, designed to roast indoors without gas and near to zero emission. Which reduces the fuel consumption, energy costs and lowers your operating costs. Better for the environment and saves you money. Installing the W1E is quick and easy, no contractors, permits or gas lines required.
