btw, welcome to HBT
I LOVE the taste of the mature final product. But I do like to know how it tastes at each stage. I like to think it's helping make me a better brewer- if not a drunker brewer!hellbender said:I personally don't. I much prefer the tast of the mature, carbonated final product but I understand how others may want to experience/evaluate the interim stages.

It's ben a while but I beleive yo have to calibrate the software by using that formula (tool) where you take a reading with a hydrometer at OG then a reading with hydrometer AND refractometer at FG. Or something like that. I'll have to take a look.FlyGuy said:Hey Denny -- good to see you back again!
Question for you -- have you had good luck using the refractometer to measure gravity of fermenting wort? I have used the calculators that factor in the conversion of sugars to alcohol in your brix reading, but I haven't found it to be adequately precise. What's your secret?
Sampling your brews at different stages helps you in determining if anything is going wrong. Not testing it along the way is foolish IMO.hellbender said:I personally don't.

Absolutely.homebrewer_99 said:...Many of us have 4-5-6-7 brews going at any one time. Unless we had 4-5-6-7 hydrometers that method would not be beneficial. It's just as easy to take a reading with a thief.
+1 I use a refractometer also and it gets me a good reference but isn't accurate. I use it to get me close during my fermentation to the carbonation time for the yeast and then have to degas a sample for hydrometer testing to get the real gravity. The refractometer is usually off by a couple degrees due to the alcohol and small CO2 bubbles on the sample glass (after the Beersmith recalculations), but gives me a great estimation of the last third of my fermentables. They are a little pricey but come in to their own on the sparge and boilDenny's Evil Concoctions said:I use a eye dropper and refractometer. No lost beer and less chance of contamination.
Most people outside of Naval Aviation don't know what QA is. Quality Assurance!david_42 said:The krausen can make reading the hydrometer a bit tricky, otherwise no problem.
Samples never get wasted around here. I call it QA. Plus, as I use buckets with spigots, drawing gravity samples helps clear the trub away.
I think he meant that he dips the mug in and pulls the sample out that way. I started with a measuring cup doing that before the turkey baster dawned on me (though I of course bought a new one for it ).wortmonger said:Why are you sterilizing a mug? You aren't dumping it back in are you after you test? I ask because that would be way bad, but if you are just testing it then no need to sterilize. You should only have to sterilize the thief or other extraction means.
