I recently read an article titled ‘Better Beer Foam Tips’ on the AHA website. They recommend:
Get your carbonation right.
Choose malts with high protein levels (e.g. crystal malts, dark malts).
Avoid low-protein adjuncts (e.g. corn, rice, sugar).
Wheat malts and flaked barley will increase head retention.
Bittering hops help with head formation.
Sanitize and rinse your equipment well.
Depending on the grain, mash at high enough temperatures.
Nitrogen- CO2 gas mix can help with foam stability.
Avoid fats and oils.
Make sure glassware is beer clean.
Carefully measure priming sugar.
Serve beer chilled.
