Hi all, I'm new here and new at homebrewing. Made my first batch in partial mash about two weeks ago (second total batch, first was an extract kit).
Made a bitter, i'm going to bottle tomorrow, seems good, but something strange happened when brewing, so here's my question.
This was the original recipe (in metric system, as I'm from Italy) for 23 L batch, 10 L boil, late extract addition, 75% efficiency:
2 Kg Maris Otter
0.5 Kg Cara-Pils
0.2 Crystal 105a
0.1 Chocolate Malt
1.5 Kg LME extra-light
0.35 kg DME light
Made my mash at 68° (154 F) without worrying about my efficiency as I planned to achieve the planned OG (1.054) adding the right amount of DME; so when I came out with an OG of 1.048 instead of 1.064, with an afficiency of 58%, I modified my recipe by adding more DME, calculated in an amount of 0.75 Kg, considering potential of my extract was 1.046 PPG.
Well, after boiling my wort, adding the extracts and diluting to 23 L I came out with an OG of 1.048, this meaning I should have added 1 kg of DME to reach 1.054.
Trying to figure out the cause of these difference, the only thing I came tois a lower SG than the one i figured (and indicated by most software).
Has anyone experienced something like this before, or have a guess about some other reason for my low OG?
Sorry for the long post and for possible mistakes in writing, and thank you in advance
