DMS is typically noticeable in which beer styles if not boiled or cooled properly?

• A. Dark ales and stouts.
• B. Porters and brown ales.
• C. Lightly hopped pale lagers and some pilsners.
• D. Strong lagers like bock.

Answer: (C)

DMS (dimethyl sulfide) comes from the malt and is volatile, so it should be driven off by a strong boil and quick cooling. It’s more likely to be noticed in pale, lightly kilned malts—the kinds used for pale lagers and pilsners—because their clean, light malt profile highlights any residual DMS rather than masking it with roast or strong hop character. If the wort isn’t boiled long enough or is cooled too slowly, DMS remains and can give a cooked corn-like aroma, which is especially evident in these lighter styles. In darker ales, porters, stouts, or strong lagers like bock, the roasted, caramel flavors and heavier malt aroma tend to overwhelm or mask DMS, so it’s less noticeable.
