How Many Ounces In a Shot of Espresso?

A shot of espresso is considered to be one (fluid) ounce, while a double shot is two (fluid) ounces.

This volume refers to the espresso shot volume (water) that gets passed through the espresso.

The weight of the coffee required for a single shot is typically 7 grams for a single shot, and 14 grams for a double shot. This can be adjusted up to 9 grams for a single and 18 grams for a double, depending on your machine and how strong you like your coffee.

A double shot should take between 20-30 seconds to brew. Most machines are calibrated to apply a given amount of pressure (measured in “bars”) to a given volume of water, which is resisted by the espresso in the portafilter. An espresso that is ground too fine will resist the flow of water too much, while a grind that is too coarse will let the water pass through too quick and result in an underextracted brew.

What is an Italian Soda?

An Italian Soda is a flavored carbonated drink, typically made with a flavouring syrup component and an unflavored carbonated component.

Italian Sodas can be purchased pre-mixed from grocery stores, though the quality isn’t usually great. The most popular way to enjoy an italian soda is to buy the components and made it yourself at home, which is as simple and mixing the ingredients together in a glass.

Fruit flavors are typically used in Italian Sodas, such as peach, raspberry, lemon, lime, strawberry, etc. A popular variation know as the Italian Cream Soda adds a vanilla or coconut flavor to the fruit flavor to create a smoother, creamier taste.

The carbonated portion can be made using mineral water, sparkling water, or plain water depending on personal preferences.

They usually don’t have any caffeine content, though they can be mixed with a tea (after cooling) for a little pick-me-up.

Italian Soda Brands

Popular brands of flavoring syrups include Torani, Monin and 1883. These brands are known for using quality ingredients, and a have a lineup of over 100 unique flavours each.

Sugar Free Italian Sodas

Sugar Free Syrups can also be used, which are typically sweetened with Splenda, though sometimes Aspartame or Stevia are used. They allow people with a restricted diet (due to a diet, or diabeters) to enjoy more flavorful drinks.
