Hey all, I did a cal. ale yeast 001, 2L starter this morning. I'm using a stir plate and there is barely a dimple on the surface for a vortex. I can see the rotation but there is absolutely nothing to indicate yeast activity. I have only done 6 or 7 starters and I've only had my stir plate for the last 3 brews. That being said, I have noticed bubbles and activity on my other starters and was confident things were working properly after only a couple of hours. I don't think I have ever used the wyeast 001 before so maybe this is normal. I've been trying to RDWHAHB. But its not working. Should I worry? Thanks.
