Hello everyone. This is my first post here but I have been lurking around for months. Just hit the 100 gallon mark so I'm still pretty new at this. Most of what I have learned came from you awesome folks, so thanks. Anyways,, I was brewing a batch of pale ale yesterday and it was 105 degrees outside (and in the garage). I took my readings with my refractometer during and after sparge and during the boil. I am now seriously questioning some of those readings and was wondering if anyone else has noticed their refractometer was off while using it in high ambient temperature. Thanks in advance for any responses.
