1 gallon mash technique

[jsulmar]

I'm trying my first all grain small batch, mashing in a 3 gal. cooler. For a 5 gal. batch in a larger cooler I normally stir every 15 minutes but for the small batch I think opening the cooler multiple times will drop the temperature too much. What do people think of just shaking up the cooler without opening the lid every 15 minutes? Any negative effects?

Given the small thermal mass of a 1 gal mash, I think your idea of swirling instead of opening it is good. Or just leave it sit. I do 5-8 gallon batches in my 13 gal (49L) picnic cooler and I stir at most once at the half-way point of the mash. Usually I don't open it up at all during the mash.

No need to stir or swirl periodically. Just do a really good job mixing it at the beginning of the mash, and leave it sit with the lid on.

I'm with dmt.... mix well at first and let it ride

Just let it sit.

Or do what Herms did, use a large sst or aluminum pot and do the mash in a warm oven.

When I mash a small amount of grains to make crystal malt I heat it to about 155 then even with a bit of heat loss it's still in the zone no need to stir
I don't even stir a 5 gallon batch

When I did small batches, I'd mash in a stainless pot in the oven. I'd set it for 170 (lowest) and keep a temp probe in the mash to make sure it wasn't rising with the ambient temp. Taking it out to stir would be no problem. I think efficiency is helped along by moving things around a little.
