Combe, et al. (2013)
- All grains: contain some degree of foam-negatives
- Crystal malts: particularly foam-negative!
- Black malt and roasted barley: foam-positives greatly outweighed foam-negatives

Positive and negative impacts of specialty malts on beer foam: a comparison of various cereal products for their foaming properties, som under Abstract/Results sier:
Cereal products differ enormously in their foam?stabilizing capabilities. Heavily roasted grains, notably black malt and roast barley, do have superior foaming properties. However, certain specialty malts, notably crystal malts, display inferior foam performance.
