I finally got some batteries for the digicam & took a pic of this ale in my new Thirsty Dog brewery glass;
http://
Beer turned out really clear with good hop flavor & bittering. Malt flavor's a little light,but present. nice head & mouthfeel from the .5lb of carapils in the mash. Overall a well balanced pale ale. Good kit from midwest for $25!

Iím kinda new to brewing. Iíve done about 6 batches (2 all grain). Can someone explain to me (very slowly) what the difference is between a partial mash and steeping grains in a grain bag for an hour? Iíve done a brew where I used about 11lbs of oats and dark malts + a lot of DME/LME. It all seems the same to me. Maybe Iím just not into the efficiency aspect. Thanks.

The difference is that with partial mash you are creating fermentables. When you steep, it is just for mouthfeel, flavor, and aroma. You may have done a partial mash and not known it. Usually you mash at a lower temperature than you steep, too.

As libeerty said, the difference is *creating* fermentables, i.e., converting starches into sugars by pulling starches (from grains/malts) and enzymes (from lighter malts) into solution and holding them at a temperature where the enzymes are active. The enzymes facilitate the break-down of complex, unfermentable starches into simpler fermentable sugars (as well as some larger unfermentable sugars).

I would describe a steep slightly differently. A steep is simply extracting stuff from the grains/malts. No significant conversion takes place. It may extract fermentable sugars, but only those that were already present.

They're not exactly *different*, in that they overlap. A mash is a stringently controlled steep, usually lasting longer than a non-mash steep since it takes longer to convert the starches than simply to extract them.

If we're talking about a 5 gallon batch, an 11 pound steep is huge, but if it's just oats and dark malts it is not a mash because neither of those contain any significant enzymes. Basically, you must have some base malts to mash---plain "2-row," pale malt, pilsner, vienna, or munich are the usual options, because they all provide enough enzymes to convert themselves plus some. In crystal or dark malts, the enzymes have all been denatured by the roasting/toasting process (in crystal, after they've already converted the fermentables in an in-grain stewing step).

Mash temps are usually 150-160F for 1 hour. Typically 153-155F.

Also you normally get about 1 lb or or so of grains to steep and if your doing a partial mash you'll get 4+ lbs of grains to actually mash.

1 Pot will work with extracts kits were you steep grains, but with partial mashing your gonna need 2 pots.

I usually wind up using three pots doin' (AHS) PMs. One steep/boil pot (2 gals, 160įF, 45 min.), one sparge/soak pot (2-4 qts., 170įF, 20 min) and a third to mix the L/DME (1 gal.). There's really no scientific/experience reason for this. I've heard that using DME vice LME will give you a beer that's closer to the intended color. I want to make sure that all the DME gets dissolved and not form a carmelized crust at the bottom of my pot.
unionrdr, Are you now a convert to PM/BIAB?

I don't understand the AHS PM instructions. Shouldn't the mash use the smaller volume of water and the sparge step use the larger volume?
