A bit disappointed to see such widely varied predictions from brewing calculators.

As they say: "All models are flawed but some are useful"


Wonder if it will taste good?

I ran the numbers for a commercially brewed Festbier on the recipe calculator.
This beer was a similar grain bill to mine, and came in at 1.055. On the recipe calculator, it predicted 1.048.


Batch size: 5 gallons (19 liters)
Brewhouse efficiency: 72%
OG: 1.055
FG: 1.010
IBUs: 22
ABV: 5.9%

MALT/GRAIN BILL
7.4 lb (3.4 kg) IREKS pilsner
2.1 lb (953 g) IREKS Vienna
10 oz (283 g) IREKS Munich (10 SRM)
3 oz (85 g) IREKS sour (acidulated) malt

We hope my beer tastes good!

I plugged your numbers in to Beer Smith at 72% efficiency and I come up with 1.054 OG for a 5 gallon batch. I've got things pretty dialed in for Beersmith.

Good luck with your brew and hope you figure out the issue. I bet it will still taste pretty good.

Here is another possibility, although rather remote…I may have misread the refractometer. But it was read two times. The wort was 74 F at reading.

Per recommendations, I adjusted the brewhouse efficiency up to 90% in my recipe calculator. After making this adjustment, it did show an OG of 1.071.

Not saying my system is that efficient, because it is not. But thought it is interesting.

What are normal efficiency ranges for those of us here? 75, 80, or 85%?

The other factor is my mash time can easily run 2 1/2 or more hours. Triple step infusion mash.

High efficiency happens.  My last 5 batches since I last re-adjusted my mill:

94%
90%
86%
83%
90%

Average 89%

Not bragging, just stating a fact that it can be higher than 80-something.

In my experience, the crush has the most to do with it.

Secondly, collection of every last drop of wort and not wasting any in the bottom of the mash tun.

Thirdly, in my particular case, I think another big part of it is because I am usually a small batch brewer, so for instance if I am trying to make 2 gallons of beer, I really need to sparge enough to get 3 gallons, because I'll then boil off about 1 whole gallon, which is like 33% boiloff rate by volume.  Most people aren't doing that.  So since I need to sparge with a greater volume percentage-wise than the average brewer, I am collecting a greater amount of sugars then too, so I can easily achieve efficiencies >90% on a regular basis.

On the other hand........ those last two batches at 83% and 90% were about 6 gallons each.  ;)

Other than that................. any gump can get lucky every once in a while.

Cheers all.  :)

i dont know how you guys do it.

my efficiency is almost always between 60 to 70% (most recent 69%). i estimate OG on software for 60%, with the expected OG calcs on the low end, so if its higher it's relatively alright.

i don't find it to be excessively costly at this rate, so i dont want to change it.

I’m normally somewhere between 75 and 85% depending on what og I’m going for
On Tap/Bottled: IPL, Adjunct Vienna, Golden Stout, Honey Lager
Fermenting: IPA
Up Next: mexi lager, Germerican pale ale

I get ~73% +/- on my setup. A bit more on lighter beers and a bit less on all malt stronger beers.

If you want better efficiency you can probably mill your grain finer.

100% agree! You will get a much better crush on the grain. Our goal is to get as little "flour" as possible, but still crack open each piece of grain. And keeping the husks mostly intact.

This last brew was probably close to 90% efficiency. The sparge was stopped at 1.024 runoff gravity. If that means anything.
