I've been trying to get ready for my first all grain brew this Sunday. I've picked out a recipe "lil sumpin sumpin" clone from a byo magazine. The recipe calls for a 45 min mash but it seems like an hour is more standard. Do I stick to the recipe or go with the longer mash? I'll be batch sparging and the grain bill is as follows:
10 lb 2 row pale
4 lb white wheat
1 lb flaked wheat
2 oz victory malt

Thanks for the help

I would stick with 60 min. 45 is probably ok, but the prevailing thought is 60 should be plenty of time for full conversion.

Yeah, I've been planning on 60 the whole time. Just had a doubt slipping into my mind that the mash time change would have some kind of detrimental effect on the beer.

Go with 60. After you've been at it a little bit and test how well your water plays with the grain, you could find you only need to mash for 20-45 minutes. But 60 is only ensuring good conversion, it will never hurt the beer.

Chances are that conversion will happen within the first 30 minutes, but letting it go longer is a safe bet. 60 minutes is my minimum, regardless of what a recipe says. That way, if there's any areas that didn't get well mixed, they'll have a better chance at getting saturated and thus convert into sugar.

Good luck on your first AG! It's a blast!

Awesome. That's what I thought. Just don't want to get off on the wrong foot.

Conversion time is REALLY dependent on your crush. If you have a great crush, you could get nearly full conversion in 15 minutes. If you have a mediocre crush (eg average home brew store), you probably won't even get full conversion in an hour. My local store's crush takes about 90 minutes for full conversion.

So if I crush my grain with a rolling pin, I should mash for like, two days?
I just bought ingredients for my first all grain batch, but I'm too cheap to buy a mill at this point.

Test for conversion using Iodine.


If the rolling pin is wooden and has been used for rolling out larded pie crust or butter cookies. You may need to wait a light year or three for conversion. If it was only used for bashing heads or the occasional squishing of a cockroach. Two or three days will be fine.

It was a "not so local" hbs crush, and since it's my first attempt, I don't really have any way of knowing if it was a good one or not. I might go ahead and mash 90 minutes or so just to make sure. Anyone had any problem keeping a rubbermaid picnic cooler tun at mash temp for 90 minutes? Will I need to add some water at some point? I think I remember seeing someone who mashed for 60 minutes and lost 1 deg.
