The most common vanilla question is: how many vanilla bean to I need to use to make vanilla extract?
According to the FDA, the legal requirement for vanilla extract is 13.35 oz of vanilla beans per gallon of extract.
FDA: 0.8 oz (23 grams/6 beans) per 1 cup (250 ml) 40% alcohol.
Anything less is just vanilla flavored booze!
Hand extraction is less efficient than industrial percolators, so it’s important to use even more beans than the minimum.
Minimum recommended beans for vanilla extract:
1 oz (30 grams/8 beans) per 1 cup (250 ml) 40% alcohol.
