1. ### Anvil Foundry High Mash Efficiency - SG vs OG outcomes question

Hi all, I brewed my second batch on my 6.5 Anvil Foundry today and copied Clawhammer's Candy Orange IPA recipe (Candy Orange IPA - Hazy Session). I am still dialing my Brewfather numbers in but today I found something strange with my SG and OG. Their recipe targets an OG of 1.046, I set my...
2. ### Mash Efficiency Correlation to Boil Off

Hey All, Had a weird occurrence happen last weekend, and I'm curious what might be the cause... We brew all grain with 3 kettles (HLT, Mash, Boil). We had what I believe was a really efficient mash. Everything hit at all the right moments, and things felt good. Then the boil hit, and we...
3. ### The Efficient Brewer

Why is my efficiency so low? Can someone explain my efficiency? I thought I understood efficiency. These statements are just some examples of the many threads relating to efficiency that I have seen on HomeBrewTalk. It would seem the forum is replete with individuals scratching their noodles in...
4. ### Recipe Numbers Not Adding Up: 5 Common Causes

Ever find a great looking recipe - on a website, in a book, or elsewhere plug it into your brewing software - and the numbers just don't add up? I'm specifically talking about the IBUs and the specific gravity. It can be frustrating! Here are the main reasons why that happens: (Note: I've...
5. ### Take the guessing out of efficiency Part 3

As I explained in the first article, efficiency is defined as the amount of extract present in the wort divided by the total possible amount of extract. This can be divided into different kinds of efficiencies that can be calculated such as conversion, lautering and brewhouse efficiency. Here is...
6. ### Take the guessing out of efficiency Part 2

Note: This is the second article in a series of 3. The link to the first one is here https://www.homebrewtalk.com/entries/take-the-guessing-out-of-efficiency.html In this article, I will explain how to calculate extract content of wort and sparging volumes. Conversion efficiency, as previously...
7. ### Take the guessing out of efficiency

When creating all-grain recipes, whatever program you use will ask to input an efficiency to calculate the OG of the beer. But what value do you enter? In BYO, they use a nominal extract efficiency of 65%. In general people are told that with experience and good brewing practices you should...

11. ### Partial Mash Efficiency Dropping from Pre-Boil to Fermenter

I brewed a partial mash recipes using BIAB method last weekend. I mashed all my grains and then added LME in the last 15 minutes of the boil. I tried calculating my efficiency using Brewer's Friend (https://www.brewersfriend.com/brewhouse-efficiency/). I am coming up with 57.4% efficiency (not...
12. ### Negatives of Low Mash Efficiency

Besides having to spend a little more money on grains to make up for a low mash efficiency, are there any other downsides to having a low efficiency? EDIT: I use BIAB with double milled grains and get ~80% which is typical. I just wanted to see what the reasons are for trying to bump the % up...
13. ### Questions about all-grain using Mash and Boil

Hello again, I'm about to acquire a Mash and Boil, and I'm pretty excited. I've never done an all-grain, only extract, and the M&B seems pretty user-friendly. After extensive reading (staying up till 3am several nights in a row), I've got some questions about achieving desired efficiency...
14. ### Am I understanding what efficiency is?

We're new to brewing (6 all-grain batches so far). We want to make sure we are understanding brewing efficiency. Our most recent batch was a single hop using 24 lbs of pale 2-row malt. So - is this correct? Theoretically, we should get 888 gravity points (24 * 37 PPG)? After mashing and...
15. ### Questions about juice efficiency

Hello HBT community, This site and its community is fantastic and has been a staple in my research when brewing and vinting, so thank you all! I looked pretty hard to find info before posting, but I haven’t had much luck. I’m seeking any intel you folks might have on the following: What is...
16. ### Sugars settling in hydrometer sample?

Hey guys, I've got a few batches under my belt with an eBIAB setup I bought and I've been trying to take a lot more samples throughout the process to find out what my efficiency is. My last batch was a while ago so I don't quite remember exactly the numbers I was getting, but basically: I'm...
17. ### Steeping grains in wort vs. water: extraction efficiency vs. tannins

After having had several bad results (strong tannin flavors and harsh bitterness) with steeping grains in our local tap water, I've tried to steep in wort instead. While I'm now not getting any tannin flavors and nasty bitter notes anymore, I'm also not getting a decent extraction efficiency...
18. ### Sudden strange efficiency issue

Hello everyone. I've been brewing on a grainfather type machine for about 2 years. Efficiency has been all over the place and just when I thought I had it down I run into this low efficiency again. I currently have 2 similar machines and did 2 batches on the same day. I usually mash for around...
19. ### Beersmith 2 Efficiency Issue

I've been using beermith for a few years now and like it for recipe formation but I've had issues with it I've never really resolved. One is that the calculations for mash water and sparging never match and frankly it kind of annoyed me that I was unable to simply run a test to set up the heat...
20. ### Estimating Efficiency for New System

I'm a brand new brewer, working with my first recipe, a clone of MadTree Galaxy High obtained from the brewery. I've input the recipe into Beer Smith 3 to the best of my ability. With the listed brew house efficiency of 82.35%, I expect my system will be a bit lower than that. I will describe my...
