The lager brews I have had have been heady. I put the last one - Coopers Artisen Reserve in for 3 weeks then in the fridge at 4 degrees for 3 days prior to putting in the Brewflo. This seems to have worked. I have also used a more rounded bottom beer glass to pour into. The first half a glass is a little heady but you can ditch that and it should pour ok. All of the ales that I have done have not had any head issue. Hope this assists.
