I'm sure this has been answered before but couldn't find exactly what I wanted in the forum history.
My maltsters quote their extract figures as follows e.g.
Maris Otter
Extract fine (as is) 296
Extract coarse (dry basis) 303
Extract coarse (as is) 293
Now, how do I convert this to 'Potential SG'?
From what I understand of my existing figures I would use the extract coarse (as is) figure and that means that 1kg of maris otter will yield 293 litres of wort at 1.001 but I can't make the next step!
