my favorite drink is red wine.
[{"role": "system", "content": "Red wine is a type of wine made from dark-colored (black) grape varieties. The actual color of the wine can range from intense violet, typical of young wines, through to brick red for mature wines and brown for older red wines. The juice from most purple grapes is greenish-white; the red color comes from anthocyan pigments (also called anthocyanins) present in the skin of the grape; exceptions are the relatively uncommon teinturier varieties, which produce a red colored juice. Much of the red-wine production process therefore involves extraction of color and flavor components from the grape skin. The first step in red wine production, after picking, involves physical processing of the grapes. Hand-picked or machine-harvested grapes are usually tipped into a receival bin when they arrive at the winery and conveyed by a screw mechanism to the grape-processing equipment. On arrival at the winery there is usually a mixture of individual berries, whole bunches (particularly with hand-picked grapes), stems, and leaves. The presence of stems during fermentation can lead to a bitter taste in the wine, and the purpose of destemming is to separate grapes from the stems and leaves. Mechanical de-stemmers usually consist of a rotating cage perforated with grape-sized holes.\n"}, {"role": "user", "content": "I really like red wine!"}, {"role": "assistant", "content": "I love it too, it's made from dark colored grapes and very delicious!"}, {"role": "user", "content": "Yes and isn't it supposed to be healthy too?"}, {"role": "assistant", "content": "It can be. I don't like when it's bitter though, that's caused by the presence of stems during fermentation."}, {"role": "user", "content": "Really? I had no idea. I thought they were really good at getting those out of the wine!"}, {"role": "assistant", "content": "They usually do, the mechanical de-stemmers have a rotating cage with grape sized holes in them to seperate the stems from the grapes."}, {"role": "user", "content": "Interesiing I had no idea they had a machine for that. Very cool! What else can you tell me?"}, {"role": "assistant", "content": "Well the color of red wines can vary from violet through to brick red and brown depending on the age of the wine"}]
