Product Description

Smoky, like smoked fish or cheese”

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

Low levels of guaiacol can find their way into cider through oak ageing. Higher levels can result from growth of Alicyclobacillus bacteria in juice prior to fermentation. Occasionally, such flavour characters can also be caused by tainting of fruit on the farm by smoke.

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

IMPORTANCE

Low levels of guaiacol in cider contribute to wood-aged complexity. Higher levels of guaiacol impart an undesirable smoky / disinfectant-like note to affected cider and the juice from which it is made. The flavour of guaiacol tends toward a more medicinal note when bromophenols, formed by the same contaminant bacteria, are also present.

ORIGINS

Low levels of guaiacol can be derived from oak ageing. Higher levels can be caused by growth of Alicyclobacillus prior to fermentation. This spore-forming organism converts vanillin in the juice into guaiacol.

HOW TO TASTE

The best way to evaluate smoky flavours in cider imparted by guaiacol is as follows. Without covering the glass, swirl the sample to release the aroma. Take a single short sniff. Repeat as necessary.

CAS NUMBER

The CAS registry number of guaiacol is 90-05-1.
