No hydrometer, no brewing for me. I do prefer a refractometer pre-fermentation however. Someone on the board has a sig: measuring is knowing. It's a must in the brewing game.

One Wyeast smack pack or White Labs vial is equivalent to 1 Billion cells.

I think your math is wrong somewhere. If you plug a 1.048 wort into Mr Malty and ask how many vials/smackpacks to pitch it does not say 180, more like 1.8. if a vial is 1 billion and you are saying that 5 gallons of 1.048 wort needs 180,000,000,000 you would need to pitch 180 Frsh vials into it to get your desired level as stated above. Perhaps litres instead of millilitres?
Yes, bad math, wrong spot though.  100 Billion cells per smack pack.

Thanks for the edit Tom.

I corrected my post to reflect 100 billion cells per smack pack or vial of yeast.

Well yeah, except where I missed the 1 vs 100 part  :(

My brewing is pretty consistent so I sometimes forget to take a reading. My most important measuring tool is the thermometer though I'd miss the hydrometor.

Funny I was thinking about this thread when I noticed the batch brewed last Sunday was finished apparently on Monday. ???

Then just realized tonight I've just been looking in the wrong fermenter and at the Kolsch that was brewed over a week ago. ;D

Pitching rate and fermentation characteristics play a large part in head formation and retention in the finished beer, so they might also have a role during fermentation.  her's a great article...
