First time using the strike water calculator can you guys help me out?

[Brewer #452450]

Hello everyone,

I'm about to do my first all grain batch and I used a strike water calculator can someone tell me if I did it right. I am at about 500 ft above sea level. I want to do a 152 F infusion for 60 mins. I will be doing an 11 lb batch. My malt will be about 65 degrees warm. The calculator said my strike water should be 166 F. Does that sound right? Something else is the standard amount of Gs of malt per lb of malt on the calculator is .31 Gs per lb of malt and I want to do a 5.5 G batch, should I add 8 Gs or something of strike water? If I'm getting 70% efficiency then I should add 7.9 Gs right?

Thanks in advance!

Sounds hot to me..
I rarely use over about 155f at about 5.5 gallons

166 for strike temp seems high to me too. Similar grain bill size, the strike temp for my 153/154 mash temps is 160.

Your numbers are all very close to mine and and most often my strike water is 166°F (74°C).
As for gravity points, different malts have different PPGs. I always go by what the recipe editor has.

11lbs or 11 gallons?
Unless it is damn cold outside, getting 8 gallons of strike water to 152 in a 16 gallon kettle with 11lbs of grain and single infusion for a 5 gallon BIAB batch should be no more than 158. 160 at the very top end. 166 would be quite warm assuming the previous. I'm in Florida at 100 ft. 100ft and 500 ft shouldn't be that big of a difference. This also assumes you are mashing in ambient temps around 50 or above. 8 above mash temp is normally a good rule of thumb using 13-14 lbs of grain. 11 should be less.

To calculate the exact strike water temperature:

Formula: Tf = ((Va * Ta) + (Vb * Tb)) / (Va + Vb)
Where:
Tf = Final mash temperature
Va = Volume of water
Ta = Temperature of water
Vb = Volume of grain
Tb = Temperature of grain

Because I mash in a picnic cooler (old school batch sparge method) I have set my mash tun heat loss to 6°F in my equipment profile. This accounts for heat that goes into the cooler itself upon adding the strike water.

That explains a lot. My kettle insulates well with a couple of towels on it, and I lose very little heat during the mash.

Hello BarbarianBrewer! It's true that each malt has a different PPG, and keeping track of the information from your recipe editor is a good way to ensure accuracy in your recipe.

Always nice when old friends drop in to say hello.

More than 3 years ago, a new trial member Mia Amelia started posting. They posted infrequently, and almost exclusively their posts were so general and, uh, bland? Not totally on-topic? Not always, a few posts seemed, uhh, less bot-like?? But 99%. Something like that. Direct messages went unanswered, as did direct questions. They stopped posting about a year ago, no activity since.

Many of us concluded it was a bot doing all that. Never figured out if that was the case, nor could anyone figure out what their game was. Still a mystery.

So when spammers post super-general messages to get their post count up, so they can post spam links (it’s a search engine optimization thing) we bring up Mia.

In the above case, the spammer posted a link, hidden in white. I deleted it, but left the rest so we could all still see it.
