Just buy a wine thief for $10 and your problems are solved! That competes with my Autosiphon for favorite piece of equipment so far that makes life easier.

I figure it's made me more paranoid than I was when I was using my turkey baster, so I'm probably safer than I was before. It's a decent product, but if you were doing smaller batches, I wouldn't recommend it, as it can be harder to fill with less than 5 gallons of beer.
I'm also putting the samples back. I would definitely classify myself as a little OCD/overboard when it comes to sanitization, but it gives me that peace of mind since I don't want to waste any of my product.

Duuuude, you're doing it wrong

When I take hydrometer samples, there is probably in the neighborhood of 2-3oz of beer per test. I drink that. So far, there is a few drops of beer wasted, at best, during each operation since not all drips and drops make it into the glass that I drink.

4 hydrometer tests is a lot for me too. I'll take a gravity reading pre-boil (AG), post-boil, and at kegging/bottling. I've only done multiple tests at the end of fermentation, for beer at least, if I suspect the beer isn't as done as it should be at the end of 3+ weeks of fermentation.

half a gallon!
its been said, but I'll reiterate, thats too much.

2 to 3 oz per reading, at 3 to 4 readings is no more than 12 oz.

Yep. The refractometer is still a good gauge of whether gravity is falling or stable, though.

Use the refractometer for your OG, and for your periodic readings during fermentation. Once you get a stable reading 3 days in a row, then you take your 1 and only hydrometer reading to get the FG.

Also, on the "3 days in a row": don't bother checking on day 2. Measure on day 1 and 3. If they're the same, you're good to go--it's not like the gravity spiked up or down and then returned to the original level!

Someone mentioned the Fermtech Thief. +1 to that. I've been using that now with my last batch and it's GENIUS.

http://www.midwestsupplies.com/fermtech-wine-thief.html

You sanitize it and the hydrometer, then dip the Thief into your fermenter. It fills up naturally (enough for a reading), then you remove it (or hold it there). You drop the hydrometer into it, spinning it as usual to dislodge any air bubbles. When you get the reading, you simply press the bottom tip against the fermenter and it slowly/gently runs the sample back down the side and into the rest of the brew. You can sample a taste if you'd like, or not sample any. It's like they combined their springless bottle filler with their auto-siphon and...voila!! So smart and easy.

I don't know what you are using to sample. My hydrometer tube takes less than 4 oz. Even if I did 4 samples, that is still only a pint. Typically, I take the first sample after adding the yeast. That sample sits next to the fermenter and gives me continuous updates. When it has been stable for 3-4 days, I draw a new sample. If the new sample is higher, I let it sit.

I test pre fermentation and then before it goes into the keg which is usually at least 3 weeks later. I don't need to babysit the thing while it ferments.
