Stronghold S7 Pro

the verdict

the s7 pro is stronghold's entry model, handling 100g to 600g batches with fully automated control and hybrid electric heating. it's built for cafe owners who want to roast small batches in-house without dedicating floor space or staff time to manual roasting. the automated profile recording is the main draw: once you've worked out a roast you like, the machine repeats it while you handle other tasks. the hybrid heating system combines convective, conductive, and radiant elements for even heat distribution, which helps with consistency across batches. trade-offs are mostly about scale. 600g max means you're roasting frequently if you're going through more than a few kilos per week, and the automation limits how much you can adjust mid-roast if you like to chase development by feel. good fit for single-location cafes, sample roasting, or anyone testing whether in-house roasting makes sense before committing to larger equipment.
