I think the issue is that I didn't know that the alcohol content would skew the results of the refratometer. It looks like it's better to use a refractometer for OG reading while brewing, and maybe a hydrometer for the FG readings when fermenting. Either that or try to decipher the hydrometer calculator lol
That's exactly what I tend to do as I got caught out using the refractometer to check FG,but when checked against the hydrometer the reading was askew as I was not using a correction factor to allow for the alcohol.
Now I use the refractometer on brew day and the hydrometer for the rest.

Never took a sample in all my life - take a clean hydrometer, rinse it in boiling water, then lift the lid and put it in the FV. Never had an infected brew doing this, but there again I only take a reading when I'm pretty sure fermentation has ceased after 2 weeks. I only really do it to check I haven't got a stuck fermentation and to work out the ABV.

In the absence of anything else (at the moment), I just sanitised an auto siphon and siphoned off just enough to fill the trial jar. Tested it with the hydrometer, and it's reading about 1.009 - 1.010 (hard to tell as I was too impatient to wait for the small head to fully dissipate.

So assuming that the Hydrometer is a good reading, (it's reading 1.000 in water)... and assuming I don't have to account for alcohol with a hydrometer? (I don't think I do)... Then...

1.039 OG
1.010 FG

ABV 3.81%

If all is true, then I'm wondering whether it's worth keeping. Maybe I'll keg it, stick in the corner and keep it a few months... see what it tastes like. I had a small sample from the trial jar, and it tastes like very bland wheat beer.

Not very impressed tbh.

Fingers crossed that my Punk IPA is going to be okay. But I didn't take an OG from it, so won't be able to work out the ABV. As long as it tastes good, the ABV doesn't matter.

Most of my FV are carboys. If I drop a hydro in I'd never get it back out!

I have been thinking I should start fermenting in buckets, it does seem to make more sense and be more practical.

I've got a fermentasaurus for my next brew, which is going to make life nice and easy as I'll be able to remove the screw jar from the bottom of the butterfly valve. Once I've dumped the trub, it'll be just beer in the collection bottle.

I never rinse my hydrometer in boiling water. I'm scared that it will soften the glue holding the paper scale in place which will then move and give a false reading. Lukewarm water and then sanitise for me.

Although wheat beers are not usually big on hops, if you are a bit unhappy about your wheat beer being bland you could always bump up the hop flavour with a hop tea or dry hop. Hallertau or Tettnager are often used in wheat beers. Another suggestion is to add coriander and orange peel (boiled to sterilise) but I have no personal experience of this so others may be able to advise if you are interested.
