Moy71 Posted June 15, 2010 Share Posted June 15, 2010 Need your help on this one folks: Irish Stout recipe: 300g dextrose, 500g DME, 23litres Yeast code: 30009 Can best before: 2/12 * Pitched yeast @ 24c * Original gravity 1040 * Day 4: SG 1016 @ 18c * Day 5: SG 1016 @ 15c * Day 7: SG 1016 @ 14c At this point, Paul/PB2 recommended I should heat to around 21c. * Day 9: SG 1014 @ 21c (2point drop due to heating and mild airlock activity as well) * Day 10: SG 1014 @ 21c * Day 11: SG 1014 @ 21c Obviously despite the heating it has stalled yet again. I have just double checked my hydrometer, plain water is showing 1012 @ 18c. I now assume that my hydrometer is not fully callibrated and that 1014 is really 1012. The beer at this point tastes very good. Any thoughts/comments please? Link to comment Share on other sites More sharing options...
Moy71 Posted June 15, 2010 Author Share Posted June 15, 2010 BTW, will be using PET bottles and so I am tempted to bottle. I am also tempted to add more yeast, but reluctant to open the fermenter at this point for fear of contamination. Link to comment Share on other sites More sharing options...
PB2 Posted June 15, 2010 Share Posted June 15, 2010 I have just double checked my hydrometer, plain water is showing 1012 @ 18c. I now assume that my hydrometer is not fully callibrated and that 1014 is really 1012. From the above, I take it that you mean water is 1002 @ 18C. Taste it. If okay, bottle.

Moy71 Posted June 15, 2010 Author Share Posted June 15, 2010 oops, you're right... 1002 @ 18c. OK, will bottle tomorrow. I mean what's the worse that could happen.. a little overcarbonation right( easily solved by letting the extra air out of the PET bottles). From the formula of getting the alcohol ABV, my FG will be around 1014 which means my alcohol ABV would be a little lower than if my FG was 1010. Is my understanding correct?

Trusty1 Posted June 16, 2010 Share Posted June 16, 2010 oops, you're right... 1002 @ 18c. Some Hydros read the meniscus diferrently, some take the reading at the top and some require the reading to be taken from the level surface of the sample. Just make sure you consitently use the same point for taking readings[rightful] . Link to comment Share on other sites More sharing options...
Slurtis Staggersalot Posted June 16, 2010 Share Posted June 16, 2010 My hydro says that it is calibrated to 15 degrees Celcius... Link to comment Share on other sites More sharing options...
John Posted June 16, 2010 Share Posted June 16, 2010 Hi Slurtis - is 15 deg considered a heatwave at your end?[joyful] Link to comment Share on other sites More sharing options...
Slurtis Staggersalot Posted June 16, 2010 Share Posted June 16, 2010 Nope 18-20 is the usual room temp, I don't know why they decided on 15 degrees, but the hydrometer was made here [sideways] I'm going to double check the paperwork that came with it but I'm pretty sure that's what it said...
