Peach brandy is a fruit brandy distilled from fermented peaches — though the name is also used for grape brandy simply flavored with peach.
Peach eau-de-vie
The closest swap. Use the same amount of a spirit like Massenez or Capovilla. Expect a drier result since it contains no sugar.
Peach-flavored brandy
Often sweetened in the US. It works one for one, but makes for a sweeter outcome.
Weaker and much sweeter than the spirit. If you use it, cut back on any syrup by about a barspoon for every 15 ml.
