MichaelH23 Posted April 17, 2011 Share Posted April 17, 2011 I'm new to brewing - today new. My question - Are there any usual readings for specific gravity i.e. upper / lower marks.[innocent] Link to comment Share on other sites More sharing options...
RoyG Posted April 17, 2011 Share Posted April 17, 2011 Welcome to the world of home brewing mate. With my brews they all vary.As an example my last Pale Ale started at 1036 and finished at 1010. I leave my brews in the fermenter for 2 weeks and then bottle. This gives it a bit of time to clear up. Hope you have success and most importantly have fun.[biggrin] Link to comment Share on other sites More sharing options...
Muddy Waters Posted April 17, 2011 Share Posted April 17, 2011 Welcome to the world of champions Michael [biggrin] There are estimates for expected gravity based on ingredients. There are too many variables for anything other than an estimate but it is usually fairly close. It all depends on yeast, ingredients, brewing temps, brewing practices. So yes, there are usual readings but they differ greatly depending on ingredients. If you need estimates/guesstimates for a specific beer we will need ingredients, volume, yeast etc. Link to comment Share on other sites More sharing options...
MichaelH23 Posted April 18, 2011 Author Share Posted April 18, 2011 Thanks to you RoyG & MW for your quick replies. With the right specs on I found the OG & FG figures on the supplied brewing card. I was worried that I did not mix properly as there seemed to be white sediment on every flat surface of the brewtube within an hour. I may be suffering first born fretting syndrome though.

AnthonyR1525228508 Posted April 18, 2011 Share Posted April 18, 2011 From what I've noticed, for a brew mixed to 23l a can will add 20 points to the SG and 1kg of sugar will ad 16 points to SG. The FG will depend on the type of sugar you use, eg maltodextrin or lactose won't ferment out 100%. If your FG (same reading 2 days running) is below 1010 you're probably right to go, especially if you are using PETs. Link to comment Share on other sites More sharing options...

Damo Posted April 18, 2011 Share Posted April 18, 2011 Does it matter if fg doesn't fall below 1010 ? I have done a few brews that haven't now & all have been good. Ive recently started drinking a cerveza , its only about 2 wks old but it tastes really , really great.Made it with BE2 & the fsg wouldnt fall below 1012 @ the 6 day mark @ 24 deg, so on good advice from "Frank" @ Coopers I bottled it anyway. (No Probs). And so if what you add to your mix can alter sg (og & fg)& I've used 2 hydrometers (Brigalow & Stevensons Reeves) both read The same in 22 deg water (1002)does anything else effect readings ?

The Brew Master Posted April 19, 2011 Share Posted April 19, 2011 G'day Damo, It depends on what you are brewing at the time to what FG reading you will get. Make sure that the sample is not carbonated & there are no air bubbles on your hydrometer at time of reading. Cheers, Peter Link to comment Share on other sites More sharing options...
Damo Posted April 19, 2011 Share Posted April 19, 2011 Hi Peter , yeh from what old hands @ the craft are saying I think you are spot on as I have been using BE's & LDM's alot which as Anthony mentions don't completly ferment out maybe... (Paul ? are we correct mate ?) And thanks for the tip but I have been decanting the sample back & forth 3 or 4 times between a couple of glasses before putting it into the sample tube to degass it.Then spinning the hydrometer to get any remaining bubbles off it. I'd been wondering if the sugars hadn't completly fermented out of my brews & yet they have been tasting like medal winners & still plenty alcoholic..[happy] Ta again Damo Link to comment Share on other sites More sharing options...
LeonardC2 Posted April 20, 2011 Share Posted April 20, 2011 I've had two brews based on the OS lager kit come out with an FG of 1.012. The 1st started life at OG 1.048,the second,at an OG of 1.044. They were 5.3% & 4.8%ABV,respectively. The first used brewing sugar,the second plain extra light DME & 2 hop additions. So 1.012 is just fine! It leaves more malty goodness for us to enjoy! No worries,m8. Here's a lil inspiration,1st & 2nd pale ales;http://i563.photobucket.com/albums/ss71/unionrdr/family%20fun/PICT00041.jpg///http://i563.photobucket.com/albums/ss71/unionrdr/family%20fun/summerpale22.jpg Link to comment Share on other sites More sharing options...
Guest Posted April 20, 2011 Share Posted April 20, 2011 Oh I see now, I was wondering how you got 5.3% & 4.8% with those readings then it dawned on me.... you bottled, duh! [sideways] Link to comment Share on other sites More sharing options...
LeonardC2 Posted April 21, 2011 Share Posted April 21, 2011 Yeah,they were both bottled with Cooper's carb drops. They work so well,I have no real desire to do it any other way.[love] I used a mix of bottles from Germany-Paulaner 11.2oz,to 12oz from rogue,Sam Adams,Michelob amber bock,Sierra Nevada,& many other craft beers that all use pop top bottles. My favorites are the German Paulaner bottles I saved from the Salvator doppel bock,& Hefeweitzen. They are a sort of dark amber with a slight green cast,like clean motor oil sort of color. And they have embossed busts of bearded monks around the shoulder of the bottle. But it was interesting that the FG on both were the same. Just the OG was higher on the 1st one,using Cooper's brewing sugar. The second one was a bit lower OG,due to my using 3lbs of plain extra light DME in place of the 1kg of brewing sugar. You'd think the DME would give a higher OG,but it clearly doesn't. Link to comment Share on other sites More sharing options...
