    A lightstruck beer occurs when iso-apha-acids come into contact with light in the near ultraviolet spectrum. The light cleaves off a side chain of the iso-alpha-acid which leads to the formation 3-methyl-2-butene-1-thiol (MTB). MTB is a ‘skunky’ compound that is detectable in very low concentrations. If a beer is to be bottled in clear glass then there must be no iso-apha-acids present unless they have been reduced.

    Synonym: Light Strike
