First time using BIABacus!

Post #1 made 10 years ago
Hey all, I just started brewing an would like your input on this recipe. I tried BIAB twice before using 1 gallon recipe kits and failed the first time because my water volume was way off and the second one the OG was very low so I suspect either my mash was not efficient or my water was off... The first recipe kit I did was a cream ale, the ingredients went like this:
0.75 lbs pale malt
0.75 lbs pilsner
0.2 lbs rice flakes
0.21 oz hallertauer 60 min
0.12 oz hallertauer 1 min
safale american us-05
I did not know any better and only had 1.5 gallons total water volume and had the heat on max for the boil so I think the boil was too strong and too much water evaporated. I only mashed for 60 minutes, did not sparge and boiled for 60 minutes.


I would like to try this recipe again so I bought:
4.4 lbs pale ale
4.4 lbs pilsner
1.1 lbs rice flakes
0.882 ounce Styrian Golding


My brew pot is only 4 gallon so I would be going for a 2 gallon recipe. The quantities I would be using are as shown in the excel sheet.
If anyone has hints or suggestion it would be appreciated!

Thanks!

Welcome to the forum RF :salute:,

It's great that you have found this forum - you are now in the right place. This forum was started because of the vast amount of confusing, let alone incorrect, new brewers are exposed to. I first discovered brewing forums ten years ago and it was easier then than now. Personally, I have no idea how new brewers manage these days if learning from the net. I take my hat off to you (and them) :salute:.

Okay, down to business...

Firstly, all-grain kits were unheard of ten years ago when BIAB was being pioneered. BIAB, unfortunately/fortunately, allowed them to happen. I say fortunately, because, all-grain kits (AGK's) aren't a bad way of having a crack at all-grain. I also say, unfortunately, because they get you thinking incorrectly.

An AGK makes you think that you will get such and such volume of such and such gravity from the kit. This is not correct. The wording that comes with them is also often very ambiguous or poor.

In your post above, I can see that you are trying to blame yourself for the problems with your first few recipes. Don't!

You've tried the kits twice and they haven't worked so let's forget them (as you have by ordering ingredients) and cover some basics.Let's start with a fresh mind as I think you want to do - that's fantastic and impressive you have jumped into the BIABacus - most brewers would open it up and say "that looks too hard!" - you've done a great job :clap:.

The Basics

- Firstly, you plan your brew first, based on your equipment, and then buy the ingredients. (AGK's work the opposite way - don't worry if that doesn't make sense.)
- Mash temps are critical. Thermometers are often inaccurate at mash temps so you can't rely on a sinlgle thermometer.
- Before taking any temperature reading, you must agitate the water, or if you have mashed in, the mash, really well as extreme temp differences occur in non-agitated liquids.
- Mash for 90 minutes. That extra 30 minutes makes a difference on nearly all grain bills.
- Boil for 90 minutes. This will correct some problems that a 60 minute boil will not.
- Don't use hot water from your tap to mash unless you have an instantaneous gas hot water heater.
- Don't use water from your garden hose.
- Create a process where you can double-check weights of ingredients and volumes of water; for example, some jugs you buy are not marked correctly for volumes (I'm possibly the only person in the world that has a jug that says 4L but only hold 3. Go figure!)
- Use the BIABacus and this forum (which you are).

Moving On to You

I've had a bit of a look online but can't find the 1 gallon AGK you bought.

Before writing more, I just want to quickly mention that the smaller the "batch" size, the harder things are to measure so don't be disappointed if you are a bit out on your 'actuals'. Even large commercial breweries have to continually adjust each batch and they are dealing with pounds of yeast, assuming dried, while we are dealing with grains. Same goes with hops.

Brewing a Cream Ale

I don't want you to try and copy the kit you have already brewed. It's really hard to try and find recipes online, AGK's or, in many books, that have what we call 'integrity'. There's a few stickied posts in the new member forum I think that contain the word integrity. What it basically means is that a high integrity recipe is one that is written in a manner where other brewers can copy them easily. They are really rare.

To date, whilst not perfect, the highest integrity recipes we have found are in "Brewing Classic Styles" and "Modern Homebrew Recipes" which you'll find, at time of writing, at the bottom of this page. Buy one or both in electronic or book form, whatever suits you best.

I'm going to have a look at both those books now and see if we can come up with a Cream Ale (a style I've brewed several times) using the ingredients you have that will work. I'm going to assume that you have bought the following ingredients...

Based on the above, this BIABacus file shows what I think you should do...
BIABacus PR1.3T - Cream Ale - RedFlag PP - Batch A0.xls
A Few Notes

You'll need 13.79 L (top of Section K) for your mash. After the mash, but before or when the boil starts, you'll need to add 3L of water (see Section W).

Your first hop addition of 4.7 grams should be added after mash-out (after you pull the bag).

Your original fermentation temp and time was too high and too long. Aim for 18 C / 64.4 F. 10 days will be plenty of time.

I think that's it!!!

Wow thanks for the reply!

I will definitely give it a try using the modifications you did to the recipe. Section K is kind of confusing to me (like what is SWN?) but as you said I will mash using 13.79L. One thing I learned from last batches is that I need something to keep track of my volume, I will probably make some identifiers on my stirring spoon at half gallon increments.

As you recommended I ordered the book Brewing Classic Styles. I already read How to Brew by John J. Palmer and loved it.

FYI the AGK I bought was http://www.everwoodavebrewshop.com/prod ... ca-ag1.htm

I figured I would try to do a type of beer that does not require too many different types of grain as I cannot get grain locally and have to order online and shipping gets expensive, as I get more experience and better success I would like to brew porters as they are my preferred style. For now I will stick with "easy" recipes to get my process working and fine tuned.

As far as the section W that you added to the sheet would that be because of the longer boil and that I would have needed more water than my kettle can handle at the mash?

Again Thanks a lot!
