The phrase "Blondie" in the coffee world is not a universal term, and its caffeine content depends entirely on the brand and preparation. In recent years, it has been most commonly associated with specific signature drinks from chains like 7Brew, while elsewhere, it refers to the "Blonde" roast profile, famously popularized by Starbucks. To get an accurate answer, it's essential to distinguish between these different products.
The 7Brew Blondie
For many, a "Blondie" is the signature flavored drink from the popular drive-thru coffee chain, 7Brew. This sweet and creamy drink is built on espresso shots, and its caffeine content varies directly with its size and the number of shots it contains.
7Brew Blondie Caffeine Breakdown
- Small (typically 2 shots): Contains approximately 128 mg of caffeine.
- Medium (typically 2 shots): Contains approximately 114 mg of caffeine, though some sources suggest it can vary.
- Large (typically 4 shots): Contains approximately 256 mg of caffeine.
It is important to note that these figures are based on the standard recipe. A 7Brew barista may adjust the number of shots, so checking directly with the location is always the most accurate method.
The Starbucks Blonde Espresso
When people refer to "Blonde" coffee at Starbucks, they are talking about the espresso roast profile, a light-roasted bean blend with a sweeter, more mellow flavor profile. Counterintuitively, a shot of Blonde espresso contains more caffeine than a shot of Starbucks' standard Signature espresso.
How Starbucks Blonde Espresso Gets Its Caffeine
- Blonde Espresso Shot: 85 mg of caffeine per shot.
- Signature Espresso Shot: 75 mg of caffeine per shot.
This difference is due to the roasting process. Lighter-roasted beans are denser than their darker-roasted counterparts because they have lost less moisture during roasting. When measured by volume, a scoop of Blonde beans contains more physical mass and, therefore, more caffeine.
Brewed Blonde Roast Coffee
Beyond espresso shots, Blonde roast is also available as a standard brewed coffee. The caffeine levels for brewed coffee differ significantly from espresso because of the larger serving sizes. At Starbucks, the Veranda Blend is a popular Blonde roast example.
- Starbucks Grande (16 oz) Blonde Roast: 360 mg of caffeine.
- Starbucks Venti (20 oz) Blonde Roast: 475 mg of caffeine.
This high caffeine content is another reminder that a lighter roast does not mean less of a kick. In fact, a large brewed Blonde roast can have nearly double the caffeine of a four-shot 7Brew Blondie.
Caffeine Comparison: "Blondie" Variations and Roasts
To illustrate the wide range of caffeine, here is a comparison table:
| Drink / Roast | Standard Size | Number of Shots | Approximate Caffeine Content (mg) |
|---|---|---|---|
| 7Brew Blondie | Medium | 2 | 114-128 |
| 7Brew Blondie | Large | 4 | 256 |
| Starbucks Blonde Caffe Latte | Grande (16 oz) | 2 | 170 |
| Starbucks Brewed Blonde Roast | Grande (16 oz) | N/A | 360 |
| Starbucks Blonde Espresso Shot | Solo (0.75 oz) | 1 | 85 |
| Starbucks Signature Espresso Shot | Solo (0.75 oz) | 1 | 75 |
| Starbucks Brewed Dark Roast | Grande (16 oz) | N/A | 260 |
Factors That Influence Caffeine Content
Several elements beyond just the roast level contribute to the final caffeine content of a coffee beverage.
- Bean Variety: Arabica and Robusta are the two main types of coffee beans. Robusta beans naturally contain significantly more caffeine than Arabica beans. While many specialty roasters use Arabica for blonde roasts, some blends may use a mix, impacting the caffeine levels.
- Measuring Method: As discussed, measuring beans by volume versus weight can change the outcome, as light roasts are denser. Many commercial establishments use precise weight measurements to control consistency, but at home, scoops are more common.
- Brewing Method: Brewing methods like espresso extract a highly concentrated shot, while drip coffee involves longer contact time with water, resulting in a higher overall caffeine volume in a larger serving size.
- Serving Size: The most obvious factor is the amount of liquid. A larger beverage, whether espresso-based or brewed, will simply have more total caffeine than a smaller one, assuming a consistent strength.
In conclusion, the caffeine in a "Blondie" is not a fixed number. It varies dramatically depending on whether you are referring to a 7Brew flavored drink or a Starbucks Blonde roast coffee. It is a common misconception that blonde or lighter roasts have less caffeine. In fact, due to the bean density, they can contain slightly more caffeine per measured scoop. When ordering, always clarify the type of drink, and consider the size and number of espresso shots to know what you're truly getting.
