Monohydric alcohol from the group of terpenes (monoterpenes). At room temperature, menthol is a colourless, crystalline solid with a peppermint odour. The natural (levorotatory) menthol occurs in many essential oils, especially in mint oils of the plant genus Mentha. These are common mint, peppermint and polemint, as well as basil, bitter melon, tarragon, marjoram, oregano, rosemary, sage, sunflower and thyme. Menthol is added to many products as a disinfectant ingredient and as a fragrance and flavouring agent. These include liqueurs, perfumes, sweets and dental and oral care products.
Menthol tones are also found in wine, for example in the white wine varieties Gewürztraminer, Grüner Veltliner, Riesling and Sauvignon Blanc, as well as in the red wine varieties Cabernet Sauvignon, Merlot, Pinot Noir, Syrah and Tempranillo. The typical peppermint sensation is fresh, minty and sweet. The taste threshold is between 0.2 and 1 ppm, but the sensation is perceived tactilely (sense of touch). It often occurs together with balsamic notes.
The Wine lexicon helps me to keep up to date and refresh my knowledge. Thank you for this Lexicon that will never end in terms of topicality! That's what makes it so exciting to come back often.
