PB2 Posted November 5, 2006 Share Posted November 5, 2006 Gravity does not go up during fermentation so you must have a sampling error with one (or both) of your readings. There is an article describing how to use the hydrometer in the July 2003 newsletter. You can download this as a pdf. Just a note that the alcohol formula has been amended since to read "+ 0.5" rather than "+ 0.2" for priming. Link to comment Share on other sites More sharing options...
Jeff Posted November 5, 2006 Author Share Posted November 5, 2006 how long should you let the beer sit in the tube before the reading? thanks Link to comment Share on other sites More sharing options...
Big Mal Posted November 5, 2006 Share Posted November 5, 2006 how long should you let the beer sit in the tube before the reading? thanks G'day c23627, It doesn't matter how long the beer is in the tube, You can test it straight away just remember to give the hydrometer a good spin as you put it in to throw off any bubbles that form around it, this could also be the reason your fg is higher than the other day as the bubbles in the beer are becoming more refined. Hope this info helps mate! Cheers, Mal. Link to comment Share on other sites More sharing options...
Jeff Posted November 7, 2006 Author Share Posted November 7, 2006 after 2 weeks it's 1020 so I guess I'll have to half sugar the bottles :? thanks guys Jeff Link to comment Share on other sites More sharing options...
PB2 Posted November 7, 2006 Share Posted November 7, 2006 Jeff, what were the ingredients, yeast strain and quantity, total volume, ferment temp, etc. ? Link to comment Share on other sites More sharing options...
Jeff Posted November 7, 2006 Author Share Posted November 7, 2006 coopers traditional draught, 1 tin of wheat, 300grms of dex, 2 packets of cascade finnishing hops & the yeast from the draught tin filled to the bottom of the fins on the barrel @20l & the temp on the sticker is @ 22-24 Link to comment Share on other sites More sharing options...
PB2 Posted November 8, 2006 Share Posted November 8, 2006 Not sure whether you are saying you added 20l to a total volume of 23l or you filled to 20l?? :? 1020 does seem a bit high though... This recipe looks like the one on a Brew Cellar brochure except you have omitted the American Ale yeast - your yeast pitching rate may be a bit low for the style of beer. Try drawing a sample off and degass it (toss it between to glasses about 20 times or so). Then put it in the flask for a SG measure. Link to comment Share on other sites More sharing options...
Jeff Posted November 8, 2006 Author Share Posted November 8, 2006 my guess is the total volume is 21L & I could not get the American Ale Yeast because the shop had just been cleaned out (burgled). just did the glass tossing & it reads 1018, should I just bottle with less sugar (I'm using grolsh 500ml swingtops) thanks Jeff Link to comment Share on other sites More sharing options...
PB2 Posted November 8, 2006 Share Posted November 8, 2006 The advantage you have is that you are using vessels that can be degassed easily. 8) PET's and kegs are excellent for this reason too!! So bottle with the normal priming rate and check them after a couple of weeks - if they look like being overgassed simply crack the head pressure from time to time until the gas level is suitable for you.

kieran Posted November 8, 2006 Share Posted November 8, 2006 There may be some atmospheric temp differences between your 'first' fg reading, and the others, as temp will change the gravity. I don't know if it will do it by 2 points though.. Link to comment Share on other sites More sharing options...
