Jack, what do you sparge in? And do you do a mashout?

Lots of homebrewers use insulated igloo coolers that are very efficient in
retaining heat. Although I have never probed the actual mash, I find that
when I mashout at 170 F and my sparge water goes in at 170 F, I get the sweet
wort out of the lauter tun at 150 F minimum, usually even hotter depending on
the speed of sparging. In such a setup, boiling water for sparging probably
isn't desirable.

tasting like tea.

Perhaps, but only a bit. It is a very accurate description of what sparge
water tastes like once the sugars are washed out of the grains.
You'd be surprised at ho wort!

From Jack:
>Yes, what and why not what?

The first question was: Is the yeast on the outside in a packet of Wyeast?
And the second was: Why not just make a starter using the yeast without
breaking the innner packet?
