Hi all, brewed a Amarillo SMASH with expected OG of 1.048. The new (cheap) refracto which I've never used before confirms this reading, however the hydro which I have always used says it is 1.060. My question is: does/could sediment in the bottom of the sample jar that the hydro sits in effect the reading? There is quite a bit in there. For a little info to help: 2kg of extra pale malt was used in 8l of water, mash for 90 mins, sparge 4 litres and topped up to 12l for the boil.
