Three weeks ago I put down a Dutch Lager with saflager 34/70. Final gravity should be around 1012. Fermenting in my temp cabinet at 12.c. Racked to secondary last Sunday and SG was 1014. Minor activity in airlock after transfer. Yesterday noticed small islands of white coloured foam on top of wort. Today they are the size of small finger nail. Checked the SG and it is still 1014. When I took the sample the islands dissapated. Beer does not taste off (a little 'spikey') but seems different to when I racked. Could be I'm paranoid. Would appreciate your views on whether it could be contaminated.
