Try category 34B: Mixed-Style Beer. From
https://www.bjcp.org/bjcp-style-guidelines/
This style is intended for beers in Existing Styles
(previously-defined Classic Style beers or Specialty-Type
Beers) that are either:
• A combination of Existing Styles that are not defined
previously in the guidelines, including combination
of Specialty-Type Beers not otherwise allowable
elsewhere.
• A variation of an Existing Style using a nontraditional
method or process (e.g., dry-hopping,
‘eis’-ing, stein bier) for that style.
• A variation of an Existing Style using a nontraditional
ingredient (e.g., yeast with a nontraditional
profile, hops with a different character
than described in the Base Style).
• Out-of-spec variations of an Existing Style (e.g.,
‘imperial’ versions, ‘session’ versions, overly-sweet
versions, etc.).
