Default Should I re-hydrate my yeast?

I've heard both yes and no, but is there some sort of guidance on this? Does it depend on the style?

I've wondered the same thing; FWIW I did not rehydrate and both of my fermentations have gone fine. Just seems to simplify the process.

There is usually more than enough dry yeast in 1 package to ferment your wort. If you do not rehydrate, you could be killing off half your yeast. There may still be plenty in there to finish the job, and there may not. IMO, rehydrating dry yeast is easy and I have had much better results since I started rehydrating.

I just started using yeast starters, and it works very well and is quite easy.

Yes. I always do when using dry yeast. Besides, it's to easy not to do it

I know it makes more sense to rehydrate, and it is easy, but I've found it still works 100% of the time I pitch dry. I am not arguing for it, just saying that if you've already pitched you'll be ok.

So really there is no reason not to. I've only done one batch so far and I did in fact rehydrate the yeast. On fermentation day 11 and all seems well

Before dry yeast cells can start fermenting , they need to absorb the water they lost during the drying Process and

the most important objective is to reduce the lag phase .

+1 I think it's just good practice to always rehydrate, but of course it will most likely still work if you don't. Here is a bit on the subject. And to answer the OP's other question, no it doesn't matter what style beer you are doing.

Yes, rehydrate.
