Used to sterilize and dunk my pyrex measuring cup like caveman3141. Just bought a 60ml hypodermic syringe a couple of weeks ago so have used that a few times recently and am really pleased with it. I spray starsan into the pyrex cup with syringe in there so the outside of the syringe gets a good coating. Draw back the plunger and suck up starsan into the syringe, give it a good shake then expel the starsan back into the pyrex cup and place the syringe in there. Usually takes 3 draws to get the perfect volume to fill my sample cylinder. Only the very tip of the syringe contacts the wort in my buckets. When drinking the sample I draw about 30 or 40ml into the syringe and expel it with a bit of force into the beer in the glass to get a bit of a head on top. Last night the head stayed right til the end on an ESB sample and I'm considering priming to style, and going much lower on the amount of priming sugar than I usually do, due to that.

Can you get accurate readings with a refractometer after sugars are converted to alcohol? Other posts on this forum report that refractometers can be inaccurate after fermentation.

I always like to taste my sample as well, but it always hurts to have to pull such a large sample out of my precious brew.

Accurate enough, I am not building rockets here.
There are online calculators that compensate for alcohol but you do have to have a good O.G. measurement to start with.
I have compared refractometer readings, after alcohol compensation, with actual hydrometer readings and have found them to be within a few points of each other.

I do the same. Spray some starsan on a paper towel to put the lid on. Then sanitize my hydro and take my reading.

I used to do the drop the hydrometer in the bucket too, but after I researched more that the wort and water needs to be mixed very very well for an acurate OG reading, I had way to many bubbles to be able to see a reading. Also the turkey baster is hard to pull a good sample because so much dribbles back in, it takes me 3 pulls to get enough for the hydro tester.

Sounds stupid, but I just sanitize my auto siphon, and pump a little into my hydrometer tube.

I have spigots on my FV's & bottling bucket. I sanitize the hydrometer & tube. Then open the spigot to fill & test. OG sample goes back in. Others get aroma & flavor test by me.

And if all you are doing is tracking fermentation it doesn't really matter the the alc mess the reading. Just make sure it is stable over a few days and then you can bottle/keg, then you can use that last little bit that always gets left in the fermenter for your FG with a hydrometer.

I use the lower half of my auto siphon as a wine thief. I lower it into the beer... give it a up/down shaking motion, and it fills with beer... even above the liquid level.
