I have been brewing for about 2 years and decided to try a lager. We made 3 5 gallon batches and used brewferm lager yeast in all three. I pitched I made a yeast starter with dme first thing inthe morning and pitched the yeast into it and let stand at about 70 degrees for about 5 hours until the wort was ready to pitch the yeast into it. I then put the wort into my fermentation chamber at 50 degrees and it has been in there for four days and there is no activity. I have no experience with lagers. Any help from the vast experience on this forum would be greatly appreciated.
