Default About the liquid WYeast slap-packs

It says to refrigerate it until use. Then slap it to activate the yeast then let it sit for three hours. It doesnt need to be room temperature before i slap it does it?

For example, i can take it right out of the fridge, slap and activate it then let it sit for 3 hours till i pitch it in the wort?

or it says i can pitch it immediately after it has been activated. whats the difference between the choices?

why would one person wait three hours OR just pour it right into the wort?

Yep, that's it. You really don't even need to let it swell. That is just a quality assurance gimmick. By smacking you are releasing yeast nutrients and wort into the yeast. You could go straight to a starter from there.

Ahh ok. So i can boil the wort, let it cool, take the yest out of the fridge, smack and activate shake it up, then pitch itto the wort?

Or would it be safer to let it sit out and warm up a little as i boil everything?

You can do it either way. But I think most guys smack it about 3 hours before they plan to pitch it..That's what I do.. I like to see it swell up so that I know the yeast is viable.. Letting it swell leads to a quicker fermentation start, at least in my experience..

I'd go with White Labs Yeast...Sure smack pack might be cool but its just dry yeast surrounded by what? Yeast nutrients... Essentially the same thing as Fermentis. I have never tried them but IM sure they work good.

In your situation I don't really think it matters much. With my liquid viles I leave them out before I start the brew day. With dry yeast I take it right outa the fridge and pitch. Or make a starter for high gravity brews.

Take it out and smack it immediately; take it out, warm to room temp, smack it; don't smack it...it's all good....these yeasties have been doing this for millenniums.

when I use a smack pack, I make a starter a few days before.

If you're not going to make a starter, I don't think there's much difference in when you remove the yeast from the fridge and break the nutrient inner-pack. Then pitch

Either way is fine. Personally, I'd make a starter like referenced above, YMMV
