Hi, I make a bottled chai concentrate (spices, tea, water). As the business is growing I am looking for ways to streamline / simplify the extraction process without introducing any strong solvents that will alter the flavour of the product. At the moment we finely grind the (mixed) spices, boil them in water for 60mins, filter off the extract, repeat this process with the same spices and fresh water. Then filter again and heat-seal in glass bottles. Any recommendations for flavourless solvents / organic acids and % and/or changes in the process would be greatly appreciated - there is a lot of literature online that I am struggling to get my head around!
Many thanks in advance.
