I have been having really high OGs reading 1.120 on the hydrometer. The batch size is 50liters and I'm hoping someone can help me with a calculation as to how much water I should add in order to get the OG down to 1.048 for an American pale ale? Also, any recommendations on yeast starters? Trying to find the best way to start up my safale us-05 or is it a bit of a time waster... better to just pitch it dry directly into the primary? Thanks for any help!
How much 1.120 wort do you have? And you want 50L of 1.048 wort or you just want however many L of 1.048 wort? For a batch this big, I think you need more than one pack of safale us-05. Rehydrate the yeast for sure.
Yeah, the final volume should be 50 liters. After the boil I'm at close to 45 liters of 120 wort. I use two packs. How would you recommend rehydrating the yeast?
I may be wrong but I think lowering the gravity is a sort of ratio. For example: 50 L of 1.048: X L of 1.120 + x L of 1.000. This works out to (I think, double check this) 40% 1.120 + 60% 1.000 = 20 L 1.120 + 30 L 1.000. Rehydrate by sanitizing about a cup of water, cooling it to ~70F, then adding the packet. Pitch that whole volume after it has a chance to rehydrate.
This is the right answer. 20 Liters of the 1.120 wort plus 30 Liters of H20 equals 50 Liters of 1.048 wort.
I am still a bit confused... meaning my hydrometer measures from 0 to 20 % extract and my reading is 12... how do I understand what the gravity of that is?
Your hydrometer should have a specific gravity reading, I.e. from 1.000-1.160. Wherever your hydrometer rests in this range when taking a reading should be your specific gravity.
It only measures in percent of extract and the numbers read 1 to 20 referring to percentage. I think it must be in Plato
