Hey folks. Haven't been on in a while. Had a question for all of you though. I last brewed a pilsner, 100% German pilsner malt and hallertaur. 148 F for the mash and a single decoction. Lagered with wlp bock yeast. Beer came out great except the head disappears quickly - both from the keg and bottle. I don't usually use regular soap on my brewing equipment and I don't think its my glasses - tested already. I did not do a protein rest. Not sure what it really is and I'm not necessarily out for an an answer as to WHAT it could be though feel free to give input. What I am after is: can I use wheat at say 5 to 10 percent bill and still have a true pilsner? Wheat has always helped with a lasting head on my beers and I love the taste at large and small quantities. In the same vein I suppose carapils would help too? Is it a true pils if I use say 5 percent carapils? Thanks all.
