I have just bottled 3 batches of a pale ale recipe that I have brewed several times with excellent results.
All 3 batches were made of a 13 lb grain bill, and each wash mashed for 75 minutes @ +/- 156 degrees with an initial temperature of 160 degrees. By design, the initial mash temperature was hotter than I had previously used, though the number fell to the target temp within 10 minutes of mashing in on each occasion.
All 3 were 6 gallon batches that were topped up to the lip of my 30l kettle with sparge water prior to boiling. Each was boiled for 90 minutes and cooled rapidly with a wort chiller.
Up until this point on all 3 batches, everything was exactly as expected, however, the original specific gravity reading for all three batches were odd; I received readings of 1.036, 1.038 & 1.036 where I was expecting a reading between 1.050 & 1.055.
In all three cases, the target final gravity was right on.
Are there any reasonable explanations for this anomaly? Could it have been an inaccurate OG reading?
Thank your for your thoughts.
