I boiled my first batch approximately 30 hours ago. It is a northern brewer American wheat with dry yeast. The plastic fermenter is under my stairs at a temp around 68 to 70. Being a first time brewer I am concerned I have seen no activity in the relief tube. Did I kill my yeast by not refrigerating it (was wrapped in a present). Should I wait a few more hours before concern? I will probably make it to my hbs today, should I get more yeast and re pitch? Any advice to put my mind at ease is appreciated. Thanks.
