I was going to mention pre-boil grav. The beauty of it is that you can do it, and dump your sample right back into the boil. PBG will tell you what your extraction efficiency is. http://hbd.org/uchima/tech/efficiency.html That's important to know, because it will tell you how well your mashing procedure is extracting the (theoretically) available sugars from the grain. Once you know that, you can calculate your expected OG accounting for boil-off.

There's a good calc for figuring ext eff here: http://www.brewersfriend.com/brewhouse-efficiency/.

But dcp is right..bite the bullet and run hydrometer readings for a couple or three batches to see what you're getting. It's worth the waste, meaning your beer will be worth the wait.

Good thread Jeff! Not sure I wanna do hydro tests either but I might explore a refractometer. I'm just following my recipes and focusing on hitting my mash temp. Once I built a 5 gal MLT it became easier. My beers have tasted good so far but would like to know the ABV%

If you want a refractometer, you can get them on ebay for under $30 shipped from China.
