Poor efficiency

Unread postby mikeschmidt » Mon Jan 15, 2018 9:24 pm

I've been making great beer but my efficiency has suffered recently. It use to be in the 70s but lately has been in the 60s.

So either...
* My grain crush has gotten worse - I don't think so
* My mash pH is outside ideal range. I have recently started adjusting my water but if anything the pH should be closer to the ideal range. BrewersFriend usually estimates it between 5.4-5.6.
* My mash schedule is not optimum - I don't think so; I have used same schedule and got higher efficiency
* BeerSmith configuration is messed up and isn't giving me correct targets meaning my efficiency is better that what I calculate
* I'm starting with too much water (25L) and/or rinsing with too much water (4L). I've increased this over time to get 19L into the keg.
* I'm not letting the malt pipe completely drain. It seems done but after I remove the pipe I see 0.5L of wort collect in the tray holding the removed malt pipe.

All of this only matters for 2 reasons
* I would like to rely on BeerSmith calculations when building recipes. This is easily fixed by assuming the lower efficiency ratio.
* I would like option of building bigger beers.

What an I asking?
* Recent updated BeerSmith profile for 20L Braumeister. I use the mobile app which has no option to import.
* Any thoughts on my list of things to check? Is anything missing?

Are you using a hydrometer? The paper inside can move around. This happened to me when I checked it with water and found it was reading .960 instead of 1.000

I have both a hydrometer and refractometer. For last reading of OG both showed the same 1.050.

Can you check back against your previous brews? Is something different? Have you changed grain supplier? Old grain? Water? Iodine test?

I brewed this weekend, and my milling was to fine. That caused the grain to form a plug in the malt pipe, so there was a poor flow. I paused the mashing and stirred, that really helped.
I manage to bump up my yield from useally around 80-85 % to 95 %.

Is your top disc free to move?

I buy supplies from 2 online suppliers but haven't kept track of efficiency based on where material came from. I can say the last few have come from same supplier and the efficiency has been poor.

I was going to buy next batch of grain precrushed so I could compare to my own crush. Maybe I buy also from other supplier to see if it matters. I'm also visiting a local brewery soon for a tour. I'll ask where they buy their grain.

Regarding my plates. I just use the standard setup so they are free to move up/down with flow.

Good call.

I have had trouble with suppliers in the past, with old stock. I now buy the freshest precrushed and store it myself.

That would be good . How you can ensure it’s the freshest, ie know the dates etc if it’s precrushed?

If you purchase from brewery suppliers you know they have the throughput (and the details). Unlike some HBS.

Also check the fermentation process carefully. :)
