I have two questions with the below recipe process I am hoping I can get clarification on so I understand why it is how it is and how it would change.

The steps of this recipe reads:

Place crushed grains in a nylon steeping bag and steep at 155 °F (68 °C) in 3.0 qts. (2.8 L) of water for 45 minutes. Rinse grains with 1.5 qts. (1.4 L) of water at 170 °F (77 °C). Add water (to save time, preferably boiling water) to “grain tea” to make 3 gallons (11 L), stir in dried malt extract and bring to a boil. Boil for 60 minutes, adding hops and Irish moss at times indicated in the ingredient list. Stir in liquid malt extract with 15 minutes remaining in boil. Keep a small pot of boiling water handy and do not let the wort volume dip below 2.5 gallons (9.5 L) during the boil. Cool wort, siphon to fermenter, top up to 5 gallons (19 L), aerate and pitch yeast. Ferment at 68–72 °F (20–22 °C).

My questions:

1) What does rinse grains mean? I thought steeping and rinsing were the same, obviously I am wrong.

2) How would the flavor, reading be effected if I did a foil boil with this recipe instead? Would starting with more water necesitate additional malt, hops, grains?

I hope this made sense and I appreciate any and all help.

I tried doing some research on my own but just got more confused.

this is a partial mash recipe not a specialty grain recipe.

when it says rinse grains it means get a second pot and put 1.5qts at 170F and let it sit for 10 minutes or so.

i wouldn't add more water. this recipe was obviously set up to be a partial boil. as such its boil gravity and subsequent hops amounts have already been calculated for you. if you did a full boil the boil gravity would change and you would get a different level of bitterness out of your hops than is intended. if you do decide to go the full boil rout you will have to recalculate the hops additions to get the same IBU.

This recipe is written for a stove top setup with small pots. If you have a large pot, like 32 qts, and the btu's to boil that much water it could easily be converted to a full boil.

Since the recipe obviously calls for two pots I would steep the grains in one and rinse by dunking the grain bag in the other, then combine the two for the boil.

The reason for the explicit instructions on water volumes is so the totals will eventually come up to exactly 5-5.25 gallons.

Others may have other thoughts, but that's what I see.

how much grain is involved? what type of grains? How much dried malt extract (DME)?

yes, the recipe sounds like a partial mash...let's see your grain bill.

Steeping is like a tea bag - for color and flavor. Partial mashes get rinsed (sparged) with hot (170F) water after conversion to stop the enzymatic activity. You are converting starches to sugars.


...and fermenting temps sound a tad warm - what does your yeast package say? if it doesn't tell you, what brand and style of yeast? most ale yeasts are 60-70, with the lower range being a better choice.

Right on, that makes perfect sense. I am still working on extract brewing so that's perhaps why I didn't get the rinse. So rinse is the same thing as sparging?

I appreciate your help clarifying!
