This is a poorly formed question. I am no expert, but as I understand it, espresso (misspelled in the question) refers to a brewing process, and Italian roast refers to a roasting process. So it's possible to use an Italian roast coffee in both drip or espresso coffee, and it's possible to make espresso using lighter roasts. The lighter the roast, the higher the caffeine content in the beans. Intuitively, this makes sense:roasting burns off the caffeine. This may be somewhat offset by the fact that a darker roasted bean gives up its caffeine more readily in the brewing process. Like I said, I am no expert. Many coffee vendors produce a variety called "Italian roast" and also a variety called "Espresso" or "Espresso Roast." These are marketing terms, and it's the vendor's choice which is roasted longer. An interesting, and related question is "which has more caffeine: espresso or drip coffee?" For the identical amount, variety, and roast of coffee bean, the answer is drip coffee. It's in contact with the beans far longer, so it leaches out more of the caffeine. For one Starbuck's espresso shot vs. a 5 oz. serving of Starbuck's house blend, it's probably about 80 to 100 mg. caffeine for the former, and 115 to 125 mg. for the latter. Remember, though, that people order a Tall (12 oz.) or even Venti (20 oz.) at The Buck, and typically get 2 or 3 espresso shots in their lattes. So it's almost certain that the drip coffee has more caffeine. I have also heard rumors that they have different half lives; that is, an espresso shot will hype you up faster but leave your system faster. I have no idea if it's true.

Dark roast coffee typically contains more caffeine than light roast coffee, which can help keep you awake longer.
Yes, if by extra bold you mean dark roast. Caffeine is destroyed by heat, so the longer roasting reduces the caffeine content of dark roast coffee (contrary to popular opinion which thinks of dark roast coffee as "stronger" somehow). By the way, the darker roast also burns off many of the subtle flavors in good coffees, which is why a lot of mass-market coffee shops over -roast their coffee, to disguise the poor quality of the beans they are using. Ergo, dark roast coffee means less caffeine, less coffee flavor (but more of that delicious charcoal flavor) and thinner body.
Because the caffeine is lost during the brewing process. But also during the brewing process, mass of the coffee bean (coffee seed to be technical about it) is reduced. So if you brew it by WEIGHT and have equal mass, the result will be MORE caffeine in the dark roast but if you brew it by quantity in the scoop, it will have less.
First of all there are two different colors of unroasted coffee beans. There are green coffee beans and there are arabica beans. While arabica type beans are much more popularly sold in stores. This is because arabica coffee is cheaper to produce. When judging a coffee by it's color in terms of roasting there are many different options and flavors. There are light roast, medium roast, full roast, or double roast. The color of these beans get darker the more they are roasted. Medium roast coffees have the most balanced flavors than the lighter or darker roasts so these would typically be more appealing in taste.
Blended coffee is 2 or more coffee varieties blended together. You can blend coffees from the same region, or coffees from entirely different growing regions. Coffee can be blended Pre-Roast, meaning the beans are blended and then roasted, or Post-Roast, meaning the coffee is roasted then blended. Pre-Roast blends would all have roughly the same roast profile while blending Post-Roast allows you to mix light and dark roasts or even similar roasts with vastly different flavors in the same blend. When coffee is not combined in a "blend" it is called Single Origin.
To make your coffee more caffeinated, you can use a higher ratio of coffee grounds to water when brewing, choose a darker roast coffee, or try a brewing method that extracts more caffeine, such as espresso or cold brew.

Light roast coffee is generally the least bitter type of coffee due to its shorter roasting time, which preserves more of the bean's natural flavors and acidity.
Dark roast coffee beans are roasted for a longer period of time than mild roast beans, resulting in a stronger and more intense flavor. Dark roast beans tend to have a bolder and more robust taste, with notes of smokiness and bitterness. Mild roast beans, on the other hand, are roasted for a shorter period of time, preserving more of the bean's natural flavors and acidity. In terms of caffeine content, dark roast beans actually have slightly less caffeine than mild roast beans, as the longer roasting process can reduce the caffeine levels.
Dark roast coffee typically has a bolder, more intense flavor due to the longer roasting time, which brings out deeper, smoky notes. In contrast, light roast coffee retains more of the beans' original flavors, often featuring brighter acidity and fruity or floral notes. Ultimately, the perception of flavor can vary based on personal preference, as some people may prefer the complexity of light roasts while others enjoy the richness of dark roasts.
To reduce acidity in coffee, try using a darker roast, adding a pinch of salt, or using a cold brew method. These methods can help make your coffee smoother and more enjoyable to drink.
Small coffee beans tend to have a more concentrated flavor and higher acidity compared to larger beans. They also tend to roast more evenly and produce a more complex and flavorful cup of coffee. Additionally, small beans are often considered to be of higher quality and are prized by coffee connoisseurs for their unique taste profiles.
