  1. after a long day of writing and recording speeches,
  2. you might find yourself unwinding with a glass of wine,
  3. but how often do you think about what went into making that glass of wine?
  4. I'm sure most of us have heard that wine is fermented,
  5. but what exactly does that mean?
  6. As someone with a background in biology,
  7. I've learned about this process quite a few times and
  8. have even made my own wine in the lab before.
  9. Although it wasn't that great
  10. as college students,
  11. I'm sure we've all had our fair share of wine or have at least tried it.
  12. So it's important to know just what we're putting into our bodies.
  13. Winemaking is a relatively simple process, which involves a complicated science
  14. making wine involves several steps including picking and crushing grapes,
  15. alcohol, fermentation, pressing malolactic fermentation and aging.
  16. The first step in winemaking is harvesting and crushing the grapes
  17. grapes are harvested when fully ripe.
  18. In an article by Ben O'donnell,
  19. he states that harvesters will look at skin thickness, berry texture,
  20. seed color and texture and whether the standards have turned from green to brown,
  21. allowing the grapes to fully ripen will also increase their sugar content,
  22. which will become important in later steps of the wine making process.
  23. After the grapes are harvested,
  24. they will be d stemmed and crushed to release the grape juice
  25. after crushing
  26. the grape juice along with the skin, begins the concentration phase,
  27. which can last several days.
  28. I stated in an article by Maisie Lyman.
  29. During the concentration phase,
  30. the juice is cooled to around 15°C, which allows
  31. the skin of the grapes to release their color compounds
  32. after the fruit is crushed.
  33. The next step is to begin the fermentation process as soon as possible,
  34. wine typically undergoes to fermentation processes,
  35. the first being alcohol fermentation.
  36. This is a step where wine becomes an alcoholic
  37. susanna Barati states that during alcohol fermentation,
  38. yeast converts sugars into ethanol, carbon dioxide and other by products.
  39. These by products typically become the flavors and aromas.
  40. The most common type of yeast used in winemaking is sacra mrs sarah vizier,
  41. which reacts with the sugar to n grapes to form alcohol.
  42. In this, in his article
  43. in Food and Science series,
  44. paul Chamber explained. Okay, I fudged that up. So bad.
  45. Ah
