This includes the 8, 12, 16 and 20-ounce lines, helping to pour the right amount of ingredients for each kind of drink. For example, an iced coffee would have coffee filled to the second line and milk filled to the third.
  • Reusable cup lines – Reusable cups also have three lines like the staple coffee cups from Starbucks, these are not for ounces of coffee however, they are just for aesthetic purposes, the barista will make the cup of coffee in a normal cup and then pour it into the reusable one.

Where Do Starbucks Cup-Sized Names Come From?

All of the coffee shop Starbucks names come from the Italian coffee languages, in the 70s Starbucks only had short and tall sizes for their standard drink range, grande was then introduced when customers said they wanted something bigger. 

Venti and Trenta then came along later, Trenta is nearly a litre of sweet drinks and is banned in some countries due to the high sugar content.

I love a good cup of coffee on Monday mornings for that pick-me-up, also love them in the afternoon, and on Tuesdays. In fact, it's fair to say that I love coffee all day everyday! So much so that I created a whole site to blog about it, answer questions and to just have a place for my frequent ramblings on the wonder that is.. coffee!
