There are now at least three brands of nonalcoholic cocktail bitters on the market.
It was formerly commonly believed that Fee Brothers bitters were nonalcoholic, but that is not true: they have a glycerin base, but the flavor extracts used in each have alcohol. Their bitters range in overall alcohol content.
When I was making nonalcoholic cocktails for events (remember events?) I was extremely hesitant to use alcoholic bitters in nonalcoholic cocktails. I've covered the issue I these posts:
- How Much Alcohol Do Bitters Contribute to a Non-Alcoholic Drink?
- Two Different Definitions of Non-Alcoholic
The three nonalcoholic bitters brands that I know about are:
Dram Apothecary: These were the first that I knew about. They seem largely to have moved into CBD beverages, but their bitters are nonalcoholic.
All The Bitter: This new brand is all nonalcoholic.
El Guapo Bitters: Their website only seems to mention it in hidden text, but a recent article about the company revealed that they are nonalcoholic. I confirmed via message with the company: "Our bitters are 0% ABV. We do not use alcohol, rather, we use non GMO vegetable based glycerin, and we built our own supply chain so we're sourcing our raw ingredients directly and make each product using a brewing process in our New Orleans manufacturing facility."
