Nextbio developed "super drop process" and its production system which is highly concentrated cold brew extraction process, using pure cold water (under 18ºC) at atmospheric pressure. Through this process, we can extract up to 24 brix of coffee and 8 brix of tea & herb without any additional concentration process within a single drip in 60 min. In case of coffee, this is almost 3 times thicker than espresso. Unlike other cold brew extraction methods, coffee and tea extracts through our self-developed core technology; super drop process retain the taste and aroma. You can feel the rich flavor until the very end.
