BEP — Barrel Entry Proof — is the 2023 release in Maker's Mark Wood Finishing Series, and it represents one of the most experimental projects the distillery has ever undertaken. Unlike previous entries, which used custom finishing staves on standard Maker's Mark, BEP starts much earlier in the process: the whiskey was distilled and barrelled at a lower entry proof than Maker's normally uses.
Lowering the entry proof means more water and less alcohol going into the barrel, which fundamentally changes how the spirit interacts with the oak. Water-soluble flavour compounds are extracted differently from alcohol-soluble ones, producing a softer, more integrated profile with greater fruit and grain expression. After full maturation, the whiskey received the now-traditional virgin oak stave finish in the limestone cellar.
Bottled at cask strength and unfiltered, BEP is one of the most elegant Wood Finishing Series releases — quieter than RC6, lusher than FAE-02, and remarkably balanced for cask strength. It also nods to bourbon history: most distillers used lower entry proofs before the 1960s, when regulations were relaxed to allow higher fills.
It is innovation that looks backward as much as forward, and a fitting next chapter for Maker's most thoughtful limited series.
