Nick Robertson, Rare Combinations
In 2017, Nick Robertson of Rare Combinations sought to found a kombucha brewery. After running into the alcohol limit of 0.5% in the United States and limited testing options, he spent a year developing an easier, more accurate alcohol detection method. Fast forward to the present, a patent was filed and over 120 alcohol detectors have been sold all over the world. Singapore, Canada, Australia, The UK, Germany, India, Spain, Brazil (Hi Lucas!), and many more. Nicholas is also a bioengineering PhD student.
