nunchi liquid-fermented coffee — Türkiye's first controlled liquid-fermentation specialty coffee, made in Ankara. While the world hurries on, depth keeps its own time.

Controlled liquid fermentation is a production approach in which the green coffee bean is fermented in a specially prepared liquid medium under defined temperature, time, and oxygen conditions. Unlike traditional spontaneous fermentation, this process uses a LAB (lactic acid bacteria) starter culture and runs inside a closed bioreactor. The aim is to release the bean's natural flavor potential under controlled conditions and produce a consistent cup profile from batch to batch. The approach lifts sensory quality while making chemical additives unnecessary. Read more: Process Characterization →

LAB (Lactic Acid Bacteria) are a group of bacteria that occur widely in nature and are safely used across food fermentation — yogurt, cheese, sourdough, and more. In coffee fermentation, a LAB culture transforms the bean's organic acid profile, producing a smoother, clearer, and more balanced flavor structure. Where spontaneous fermentation lets random microorganisms take hold, the controlled process uses selected LAB strains — which delivers consistency and safety. Read more: LAB Science →

Controlled fermentation reshapes the organic acid balance inside the bean. Citric and malic acid ratios shift while a rise in lactic acid produces a smoother, more polished acidity in the cup. The result: flavor and aroma layers feel more defined, clearer, and more balanced. Fermented coffees evaluated against the SCA cupping protocol show consistent improvements in sensory scoring compared to traditional processing methods. This effect is framed in terms of sensory profile and process control — not as a health claim. Read more: Why Smoother? →

Fermented coffees suit experienced drinkers and people new to specialty coffee alike. Controlled fermentation softens harsh, sharp notes and produces a more approachable cup profile. If you're not sure which blend fits you, our Coffee Selection Guide can recommend the best match for your palate.

The core difference is in the production approach. Most specialty coffees are processed by post-harvest spontaneous fermentation or by washing. nunchi coffee applies controlled liquid fermentation to the dried green bean — with a selected LAB culture, in a closed bioreactor, under defined conditions. The process has been scientifically validated in collaboration with Istanbul University. The result: a repeatable, measurable, and traceable cup profile. Read more: Process Characterization →

Controlled fermentation produces a roughly 10% reduction in caffeine, verified by HPLC analysis. That reduction does not make the coffee caffeine-free — fermented coffee still contains a meaningful level of caffeine. The information may matter to people sensitive to caffeine, but the product is not positioned as "low caffeine." Read more: What Happens to Caffeine? →

Mold and mycotoxin risk is monitored from lot selection onward. The closed bioreactor environment limits ambient contamination; the LAB culture's competitive exclusion mechanism suppresses the growth of unwanted microorganisms. The process is evaluated under EU regulation 2023/915. Our approach is built on "prevent before the problem appears" rather than "intervene after the fact." Read more: Mycotoxins and Safety →

No. No chemical additives or artificial flavors are used during fermentation. The flavor and aroma layers in the cup come from the controlled transformation of the bean's natural compounds. LAB culture, water, and time — those are the only components of the process.

This product is not positioned as a probiotic and makes no medical or therapeutic claim. Fermentation is a production process applied to improve sensory quality and flavor profile. Some of our customers have reported a more comfortable stomach experience; this has not been clinically verified and is not presented as a health claim.
