Hi
I am new to home-brewing and this is my first post, so please go easy on me!
I have just done my first partial mash brew and needed about 49 gravity points from my DME. Unfortunately I overshot my OG by quite a bit (it was 1.066 instead of 1.057)
I used an online calculator (Brewersfriend) to calculate the amount of DME. Using the metric calculation, 3kg of DME in 23 litres shows an OG of 1.049 (so I used 3kg). After much head-scratching as to why my OG was high, I checked the imperial calculation which shows 6.6lb of DME in 5 gallons giving an OG of 1.059 - I would have expected the OG to be virtually the same in both cases and think this variance is why I overshot
I think the B/F tools are excellent, but I want to try and make sure I’m using the right amount of extract. As I have seen quite different values for DME (light) can someone please advise which of the above calculations is correct so I can adjust my weights accordingly
Many thanks
Richard
