So I had a good brew day and pitched the dry yeast at about 21 celsius. It is now 26 hours later and there is no activity. I used an American West Coast Ale yeast. Unfortunately I do not know which brand as the homebrew store I bought it from had repackaged it in a vacuum sealed package. I have some yeast that I harvested from a Weissbier that I bottled a week ago and was thinking I should just throw that in for good measure. Any thoughts? Advice? I am new to this and this is only my 4th brew.
