Product Description

Geosmin, like sugar beets or damp soil”

Certified cider flavour standard used to train professional cider tasters to recognize and scale the intensity of geosmin character.

Earthy notes can be caused by a variety of microbially-derived taints. Geosmin, which produces a flavour like that of sugar beet or beetroot, is one of the most common flavours of this type. The flavour can be imparted to cider through use of tainted fruit or dirty filter pads.

Food grade | free from sensory impurities | extensively tested | safe to smell and taste.

IMPORTANCE

Geosmin imparts an undesirable earthy note to cider which is reminiscent of sugar beets or damp soil. Associated with a moderate degree of consumer rejection. Ciders contaminated with geosmin can be described by consumers as ‘dirty’ or ‘contaminated’.

ORIGINS

Geosmin is imparted to cider through use of tainted fruit. Dirty filter used to filter finished cider pads have also been implicated in development of such flavours. The ultimate source of the taint is usually growth of Actinobacteria or certain fungi (including Botrytis and Penicillium).

HOW TO TASTE

The best way to evaluate earth, mouldy flavour notes arising from contamination of cider with geosmin is as follows. Without covering the glass, swirl the cider to release the aroma. Take a single short sniff. Repeat as necessary.

The CAS registry number of geosmin is 23333-91-7.
