Vegans consider themselves to be health-conscious individuals who adhere to a vegetarian lifestyle with the exception of not consuming any food made with or contains animal products or byproducts. This often means abstaining from eating red meat, dairy products, and eggs, though many vegans choose to eat only organic produce. There are a number of excellent vegan winemakers in Australia and abroad, who pride themselves on using natural, antibiotic-free grapes grown in rich soil without the use of animal biproducts. They take great care in the vineyards where their grapes are grown, and the wines produced are both delicious and healthy. Some winemakers go even further, practicing what is called "slow wine making", in which a grape variety is grown for up to four years, allowing the vines to fully mature and produce sweet, full-bodied wines - sometimes in as short as eight months.
