Product Description

Acetaldehyde, like green apple, emulsion paint or white wine”

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

Acetaldehyde is produced by yeast during fermentation. It imparts an apple-like flavour to cider, perceived as somewhat like emulsion paint as the concentration is increased. High levels can be indicative of process problems.

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

IMPORTANCE

Acetaldehyde is present in all ciders. Low levels of acetaldehyde contribute to apple character, cleanness and complexity of cider. Acetaldehyde is an off-flavour at high concentrations when the note resembles emulsion paint.

ORIGINS

Acetaldehyde is produced by yeast during fermentation. High levels of acetaldehyde are indicative of fermentation problems, poor control of dissolved oxygen during maturation or packaging or spoilage by Zymomonas bacteria.

HOW TO TASTE

The best way to detect acetaldehyde flavours notes in cider is as follows. Cover the cider with your hand and swirl the glass to release the aroma. Remove your hand and take a single long sniff. Repeat as necessary.

CAS NUMBER

The CAS registry number of acetaldehyde is 75-07-0.
