Default best method to check gravity

Hi, Im a first time brewer. What is the best method to check OG and FG and not waste too much beer? Im having trouoble finding a larger beaker type vessel that my hydrometer will fit in.
I have been told not to put the hydrometer directly into the fermentor.

You can use the tube the hydrometer comes in or one that is for testing that has a base on it . Slightly larger. It can easily be found online. A traditional beaker is wide and short. You can put the hydrometer in the fermenter if you sanitize VERY well.

Here is one:http://www.northernbrewer.com/shop/e...-test-jar.html

Prior to fermentation, use a refractometer. It uses just a few drops. I got mine a couple of months ago off of eBay for about $26 delivered from Hong Kong. It makes it very easy to adjust the length of your boil on the fly in order to meet the OG you are shooting for. Once fermentation has started you should use the hydrometer. Any LHBS store will sell you a cylinder for testing gravity. Personally, I don't even think about checking gravity until my beer has been fermenting for about three weeks and I am getting ready to keg or bottle.

+1. I've also used a friend's refractometer, but you're going to have to sanitize whatever you use to get beer out of the fermenter anyways... might as well just sanitize the hydrometer and put it in the fermenter. If your sanitation is diligent though it's no problem.

Please don't return the sample... it begs for an infection. Just drink it.

only if you sanitation is bad, its exactly what it designed to do.
if its not sanitary enough to return, it wasn't sanitary enough to dip into your fermentor

But we never know if an existing bug is contained in the beer thief. So if you don't return it, then you just might avoid a problem.

Bingo Jethro! Not worth the risk IMO. Plus its fun to taste at different stages.
