Choosing malt depends on the style of beer.
Choosing the right malt is crucial and depends on the style of beer you aim to brew. Generally, the darker the finished beer, the darker the malt you should use. However, exceptions exist, such as dark lagers and white stouts, which break this rule.
For instance, using a dark malt in a Pilsner would be inappropriate and alter its characteristic light colour and flavour. It's important to match the malt to the beer style to achieve the desired taste and appearance.
