Hi, me and my partner are new in this business of liquors and liqeuers and have been experimenting with natural botanicals and grains infused in a base product (no preservants added). We actually have 5 formulas using GNS, bourbon and corn whiskey bases. At first all of the formulas worked fine but as time passed by scent and flavor faded away a couple of months later. Is it because we are using natural ingredients? A lack of preservants? What kind of chemical reaction are we having? They are stored in transparent bottles in a dark place.
How can these be stabilized so it can be sold to the public?
Thanks for your feedback!
