In wine and beer, 4-EP is produced by the spoilage yeast Brettanomyces. When it reaches concentrations greater than the sensory threshold (140 µg/L) it can give the wine aromas described as barnyard, medicinal, band-aids, and mousy. In certain Belgian beer styles, a high 4-EP level may be desirable; however, very high levels of the compound in wine can render it undrinkable. The level of 4-EP is roughly proportional to Brettanomyces concentration and activity, and can therefore be used as an indicator of the yeast's presence. There are significant differences between strains of Brettanomyces in their ability to produce 4-EP.
4-EP is also a component of castoreum, the exudate from the castor sacs of the mature North American beaver (Castor canadensis) and the Eurasian beaver (Castor fiber), used in perfumery.

-Methoxybenzyl alcohol was used to study the photocatalytic oxidation of 4-methoxybenzyl alcohol to p-anisaldehyde.General description
4-Methoxybenzyl alcohol on condensation with the silanol groups of fumed silica nanoparticles yields modified silica nanoparticles. It undergoes catalytic photooxidation by flavin-zinc(II)-cyclen complex to yield the corresponding benzaldehyde
