Didn't use 5.2 on that mash but I think I'm not getting the sparge water up high enough to get the grain bed up to 170. Beersmith doesn't account for that and only tells you to add x gals at 170 which DOES NOT get the grain bed up to 170.



Could be a good place to start. If you are doing multiple batch sparges you could slowly bring it up.

You either get the appropriate amount of sugar out of your grain or you dont. If you end up with less wort but the right OG then you didnt pull out enough sugars. If you end up with 5 gallons but a higher OG then you pulled out more than you expected


But if my evaporation rate is much less, then my mash efficiency hasn't changed.

I've done hand calculations and beersmith. Mash efficiency is calculated pre-boil. I don't think my post-boil volume has anything to do with mash efficiency. I guess i won't be sure until my next brew, of how volume effects mash efficiency.

He was talking about the pointlessness of brewhouse efficiency to a homebrewer.

Well i agree with that. But i think he was referring to my mash eff. I mean unless i drained off more wort from my mash, i can't really know for certain if my mash eff. would change. I can see a possibility of it going down, but until i do it, i won't know. But also, if my wort loss is less, then it shouldn't really effect my evap. rate.

I see the brewhouse efficiency is good at getting all the parts of your brew dialed in for consistency.

Take my brewing for example. My last 2-3 batches i've been short on wort volume at fermenting time. If i can get my evaporation rates calculated properly, i may be able to fix this. This could mean scaling my recipe up to 5.5 gallons

I agree with the statement above.

Your total volume and OG have a direct connection to your mash efficiency though. You are shooting for 5 gallons at X.XXX OG. If you do not get that then your mash efficiency was off of what you expected it to be.

I don't think there is anything we are really arguing about. I think I use on calculation for the same information that you are trying to use 2. In the end I am trying to ensure that I get 5 gallons at the OG I planned on, and that is all that I am concerned about.

In your cases though, had you ended up with 5 gallons of wort your OG would have been significantly lower than you wanted, meaning that you didn't pull off enough sugars from your mash. the fact that you didn't have enough sugars in your wort has nothing to do with the boiling and transferring to the carboy/bucket. It all has to do with your mashing/sparging technique.

Because what you will do to fix it is add more water to your mash/sparge which will only dilute the wort. So you can either determine why you aren't pulling out more sugar or add more grain to compensate for the lack of mash efficiency.

Again though, i don't think i can say that definitively without brewing again with that adjustment.

Also, how much wort do yall collect pre-boil? I collected 6.5 gallons the last couple boils, and it is where i come up short.

Well you see, that's the thing. I could have collected more without adding more sparge water. I had a bit more sparge leftover on top my grain bed, and i believe i could have easily gathered another 1/2 gallon or more to the wort.

I guess this is where i think that my efficiency might not change as much, because i'm still extracting the sugars. I understand if i'm upping my sparge volume.

Again, I think i will only know for sure when i brew my next batch.

Estimated about 7-7.5 gals.

Well my next brew is a Blackberry Wheat ale. So i think i'll keep the same grain bill for a 5 gallon batch and pour some more wort into the brewpot. And by next brew, if my efficiency drops, i'll know to prepare for 5.5 gallon brews.

Also, of the hop varieties i have, what would you dry hop with?


I'd dry hop with the Citra and Cascade. But that's just me. I'm on a big time citrusy hop kick.

Zappos sells hops now?
