Re: lalvin d47 yeast
As a DIY co2 user, I'm always looking to make my system more efficient and improve output. For the longest time I focused exclusively on the yeast, Mixing, storing, oxygenation, temperature variants. Like you, if I didn't see something happening within an hour I was worried. Shaking this mixing that, when all I had to so was wait. Yeast likes to take its time, you can't set your clock by it trays for sure. While 4 hours may seem like an excessive amount of time, keep in mind, the outside variables can play a big role in how quick things happen. I have seen it take over 12 hours to get a good reaction going, it all depends on the variables. I won't get onto all of them, unless you ask, but don't panic just yet.
