Made my third extract batch today and everything seemed to go smoothly - until I took a sample from the wort before pitching my yeast and did an original gravity reading. I’d forgotten to do it on the first two batches - they turned out nicely but I wanted to learn more about my final product. According to my recipe, for an American Pale Ale, my OG should have been around 1.053. It is 1.100. Barley wine territory. Adjusting for 74 degrees up in the kitchen, that’s 1.1017. Here’s my recipe:
OG 1.053
FG 1.010
IBU 48.47
ABV 5.66 %
SRM 4.86
Specifics
Boil Volume 3 gallons
Batch Size 5 gallons
Boil time: 40 minutes
I have to say that hydrometers have never struck me as what you’d call precision instruments. But this is probably user error. What did I do wrong? Is this repairable by, say, adding some boiled/cooled water to dilute the wort at this early stage, whether or not the yeast has been pitched? Suggestions, please! And thanks.
I do three gallon extract batches and 7 lbs of extract looks about right for 1.100 (Belgian Dark Strong neighborhood for me).
Did you intend for the batch to be 3 gallons or 5? It looks to me that Beersmith gave you measurements for 5 gallons when you intended on it being a smaller batch size. These are easy mistakes to make. Also check the setting for Extract vs Partial Mash vs All Grain… and also the preset systems vs “My System”… those will all change the numbers that Beersmith gives you.
You can dilute. I do it all the time. You may have to adjust your hop load though after diluting (do a dry hop addition that wasn’t planned etc).
Kat: (Palm to forehead). That’s exactly what I did. I was using the Palmer method of pitching the (rehydrated/proofed) yeast into the cooled 2 gallons of water. I was so determined to remember to take the OG reading before any fermentation had begun that, without thinking, I did so in the concentrated wort. I may also have gotten confused as Palmer says in a separate entry, “Check the gravity when you are ready to pitch the yeast.” I did (from just under the surface, re Jim’s question) - but it was highly concentrated. D’oh! But thanks.
Ethison: Nope, was making 5 gallons but as noted in previous reply, I took my reading in the concentrated 3-gal. wort. (I thought that sample smelled strong :-[) I did check those Beersmith settings when setting my recipe so I’m probably ok with this recipe. I was aiming get a typical pale ale strength but to lighten the color somewhat from my previous two brews, and took a suggestion to start the boil with DME and add the LME a bit later, 10 minutes into the boil. In any event, won’t be taking another hydrometer on this batch as fermentation has begun. Besides, I knocked it off the kitchen counter last night. Those little steel balls are hard to vacuum up.
When you are doing extract batches it is easier to determine the OG using math.
If you know you have X pounds of LME/DME and Y gallons in the fermenter, just add up the points per gallon from the extract and divide by the total gallons in the fermenter.
It is difficult to get wort and water to completely mix and when you take a sample for a hydro test, you get a sample that is more water than wort or visa versa.
Mainebrewer: Thanks. I found a formula online that does exactly that, but uses a different multiplier re points per pound for DME vs LME. http://www.picobrewery.com/askarchive/gravity.html. Using my recipe, it worked out like this:
4 lbs. LME x 38=152
3 lbs. DME x 42=126
152+126=278/5=1.0556
I was shooting for 1.053, so not too far off? And do you or anyone else have any thoughts on the different values the link author uses?
LME usually runs around 35-36 points per gallon and DME usually runs 45-46 points per gallon.
So the author is a little high on LME and low on DME, it averages out in your case since you used close to equal parts of each.
Ah good. Well at least you got it figured out. As mainebrewer said, you should be pretty damn close to your estimated OG, so you can just kinda wing it. I’ve had to do that before. I feel your pain with the broken hydrometer… I’ve broken three.
Although I’m curious… I can’t say that I read Palmer word for word, but I don’t remember anything about pitching yeast into dilution water… did he have a reason for that? I don’t understand why you would want to do that.
Thks for the feedback and sorry for the delayed response. I went back to re-read Palmer and I believe I misunderstood him - he says to pitch into the cooled wort. I poured the wort into the dilution water immediately after that and after taking a peek while dry-hopping six days later, it appears everything worked out. But what in your view would be the difference? It seemed to me - geez, maybe I read this somewhere else - that with the (rehydrated) yeast already in the dilution water, I’d help get it working on top of agitating the bucket for a couple of minutes once sealed.
