the verdict

the Probatone 12 sits in the workhorse category for small specialty roasteries, handling 2 to 12 kg batches with gas heat and profile logging. this capacity works for operations roasting 150 to 500 kg weekly without running constant back-to-back batches. the 12 kg ceiling gives you room to grow from cafe sales into wholesale accounts or online distribution. expect the same fixed-airflow design across the Probatone line: gas modulation drives your profile changes while fan speed stays constant. roasters familiar with this approach appreciate the simplicity; those coming from variable-airflow machines need time to adjust their technique. the profile logging software tracks your curves and helps maintain consistency across different operators. build quality matches Probat's reputation for longevity, with materials and construction meant for decades of service rather than replacement in five years. price runs higher than comparable 12 kg machines from other brands, but resale values hold better if you eventually upgrade. this model makes sense for roasters confident in their volume growth and willing to pay upfront for long-term durability and german engineering.

strengths

  • 12 kg capacity handles growth from cafe to small wholesale operation
  • profile logging provides consistency and staff training capability
  • 2 kg minimum allows sampling and small experimental batches
  • proven probat durability with parts support and service network

trade-offs

  • fixed airflow limits control options compared to variable-fan designs
  • higher purchase price than competitors at this capacity
  • 12 kg maximum becomes restrictive for larger wholesale growth
  • learning curve if transitioning from modern airflow-adjustable machines
