Yea this is the second time I’ve ordered from them but the first time contacting there customer service. The representative that contacted me back said "In the future it may not be a bad idea to have some dry yeast on hand just in case the liquid yeast is not viable after traveling for days and days. The yeast is quite resilient though, so I don't anticipate you having issues with it, just wanted to suggest it, just in case". Is this something that is a common problem and how do I know if my yeast is bad? Please don’t kill me for asking what may seem like an ignorant question I’ve only brewed once and it didn’t go that well. So I'm a little nervous, but I bought what appears to be good equipment and am more than willing to learn. Thanks for your help.
