As an expert sommelier and brewer, I can tell you that there are indeed differences between Helles and lager. Helles is actually a subcategory of lager, specifically a German style of pale lager. While both Helles and lager are lagers, there are some distinct characteristics that set them apart.
First and foremost, Helles lager is known for its sweeter taste compared to other lagers, including its Czech cousin, the Czech Pilsner. The sweetness comes from a more prominent bready malt presence in the Helles, giving it a slightly maltier flavor profile. This sweetness is often balanced by a mild hop bitterness, but it is generally less hoppy than other lagers.
In terms of appearance, Helles lagers are typically golden yellow in color. However, it's worth noting that there can be some variation among brewers, as some may take liberties with the style and experiment with different shades of gold or even slightly darker hues. Ultimately, the color should still be within the range of a pale lager.
In terms of body, Helles lagers are traditionally medium-bodied. This means that they have a moderate amount of body and mouthfeel, which adds to their overall drinkability. The medium body helps to balance the sweetness and maltiness, creating a well-rounded beer.
It's also worth mentioning that Helles lagers are often associated with German brewing traditions and craftsmanship. The Germans are known for their meticulous attention to detail and their commitment to brewing quality beers. This dedication is reflected in the Helles lager style, where every aspect of the beer is carefully considered and executed.
