first time brewer... I stuffed up and added yeast to just boiled water with the malt and sugar. Is there any chance the yeast will have survived or should I just bin it and start again? Thanks!
In this situation, brew it as normal and get it into the fermentor. The wort should be fine for a day as long as your initial sanitation was good. I routinely do lagers this way. Make the wort, transfer to carboy and chill it overnight, pitching the yeast in the morning.
Put the fermentor of wort in the coolest place in the house or basement. Make it a priority to get a fresh pitch of yeast from the brew store the next day.
Not a chance that your yeast survived boiling water, but continue the brew and then cool it normally. After you have done that, pitch new yeast or whatever drips you can get out of your first container into the wort and see what happens--no reason to throw it out.
Alternatively, if you only have your empty yeast container (and not an extra new container full of yeast) then put about a cup of water at about 105 degrees F into a sterile container and mix in about a teaspoon of sugar. Then add what ever drops of yeast you can squeeze out of your empty container. Give it a couple of hours. There is a chance that the yeast will take off in there. After a couple of hours, just pitch it into your wort.
