Beck’s is a pale German pilsner brewed by Beck’s Brewery headquartered in Bremen. The actual beer you drank was likely brewed in St. Louis, however, as Beck’s is wholly owned by AB InBev.
Pale Lagers as a style are usually straw colored, up to a light gold with a white head. The flavor is very light and dry with only slight malty sweetness. A little crisp hop bitterness without too much hop aroma.
Most “macrobrews” will be somewhat similar, though the stock “American” variant of Pale Lager like Budweiser or Miller will have a corn sugar flavor to them and likely be a bit lighter in body. Beck’s claimed to adhere to the German Beer Purity Law which would prohibit the use of an adjunct like corn.
