The Ancient Tonic: Drinking Vinegar (Kurozu)
Perhaps one of the most distinctive and health-conscious Japanese practices is the consumption of diluted vinegar before a meal. Known as kurozu (black vinegar) or simply su, this tradition is rooted in a belief in the health-giving properties of vinegar, which dates back centuries. The vinegar is made by fermenting grains like brown rice and is rich in beneficial acetic acid.
Many Japanese people drink a small amount (15-30 ml) of this diluted vinegar for its numerous benefits, including:
- Improved Digestion: Acetic acid is believed to stimulate the production of digestive enzymes and stomach acid, helping the body break down food more efficiently and improving overall gut health.
- Blood Sugar Regulation: Studies suggest that consuming vinegar before eating can help regulate blood sugar levels, particularly after a carbohydrate-rich meal, by improving insulin sensitivity and reducing post-meal sugar spikes.
- Enhanced Metabolism: Some research indicates that vinegar may aid in weight management by boosting metabolism and promoting feelings of fullness, which can help reduce overall calorie intake.
- Detoxification: By supporting liver and kidney function, vinegar can assist the body in its natural detoxification processes.
- Skin Health: Antioxidants and a balanced pH can contribute to clearer, healthier skin.
A Daily Staple: Green and Barley Teas
For many Japanese, a simple, warm cup of green tea (ryokucha) is a standard companion to any meal. In restaurants, it is often served free of charge. The benefits of green tea are widely recognized and include:
- Rich in Antioxidants: Green teas, especially matcha (powdered green tea) and sencha, are high in catechins, a potent antioxidant that supports metabolism and cellular health.
- Aids Digestion: Teas can help with digestion and reduce bloating.
- Supports Weight Management: The combination of caffeine and catechins can help boost metabolism and promote fat burning.
In addition to green tea, mugicha, or barley tea, is a popular caffeine-free alternative, particularly during the hot summer months. It is known for its mild, nutty flavour and hydrating, cooling effects, which also support digestion. While not always served strictly before the meal, it is a common pre- and during-meal beverage.
Formal and Social Aperitifs: Sake and Highballs
In more formal settings, such as the exquisite multi-course kaiseki dinner, an alcoholic aperitif known as shokuzenshu may be served. This small, seasonal drink is meant to awaken the palate and prepare the senses for the meal to come. Options might include a light, aromatic sake or a sweet plum wine (umeshu).
For more casual social gatherings, particularly at izakaya (Japanese pubs), it is customary to start the meal with a group toast, or kanpai, often with beer or sake. A whisky highball (haibōru) is another very popular choice, combining Japanese whisky with soda water. These social drinks serve a convivial function, breaking down formal barriers and celebrating the shared experience of dining.
Comparing Pre-Meal Japanese Drinks
To illustrate the variety, here is a comparison table of common Japanese pre-meal beverages:
