Kaffelogic is a Wellington-based roaster manufacturer that entered the market in 2017 with a focused product line aimed at sample roasting and home use. the company builds fluid-bed machines with an emphasis on software-driven profile control and compact footprints. their approach centers on pid automation paired with proprietary look-ahead and gain scheduling algorithms, which they claim deliver repeatable roasts without manual intervention. the Nano 7e sits in the professional sample roaster category but also markets to serious home roasters who want lab-grade control in a countertop package. Kaffelogic machines are fully manufactured in New Zealand and use powder-coated steel and aluminum construction. the company provides roast profile software (Kaffelogic Studio) that allows users to create, save, and share curves via usb-c connection. they're known for tight batch size windows and a plug-and-play philosophy with preloaded profiles. buyers tend to be green coffee traders, roastery quality control teams doing sample evaluation, or home roasters comfortable with structured batch sizes and software-based workflows.
the base Nano 7e roasts 90 to 120 grams per batch in standard configuration. Kaffelogic offers an optional Boost Kit (anodized aluminum inserts that attach to the roast chamber) which extends the range down to 50 grams and up to 200 grams. without the kit, you're locked into that 90–120g window, which works well for cupping and sample evaluation but limits flexibility if you want smaller test batches or slightly larger home roasting runs. roast time averages around ten minutes with a four-minute cooling cycle.
no. the Nano 7e ships with fifteen preloaded profiles accessible directly from the machine's control panel, so you can roast without connecting to a computer. the Studio software is optional and adds profile customization, real-time data logging, and the ability to save and share roast curves. if you plan to develop specific profiles for different origins or processes, the software becomes more useful. for straightforward sample roasting or dialing in a consistent home roast, the onboard profiles cover most needs.
Kaffelogic makes sense if you prioritize automation, small footprint, and tight pid control in a fluid-bed format. it suits roasteries doing regular sample evaluation, importers cupping multiple lots, or home roasters who want repeatable results without manual heat adjustments. trade-offs include the fixed batch size window (even with the Boost Kit, range is limited compared to some competing sample roasters), lack of waterproofing for cleanup, and reliance on software for deeper customization. if you roast varied batch sizes or prefer drum roasting, other platforms may fit better.
