If you mean which drink is most likely to help, there isn’t a drink proven to reliably “reduce gastroesophageal reflux” for everyone.
Water: generally the safest choice; sip slowly.
Ginger tea: may help nausea and digestion, but evidence for directly treating reflux is limited.
Chamomile tea: may be soothing for some people, though evidence for GERD is limited.
Avoid mint/peppermint, coffee, alcohol, carbonated drinks, and acidic juices if they worsen your symptoms.
If you tell me the name or ingredients of the specific drink, I can assess whether it is likely to help GERD.
