Brewing Potsize

VinylJunkie · 14-10-2016 9:04am #1

So, I'm getting back into brewing after a 4 years or so, I have all the equipment from before, picked up some glass bottles and this American Pale Ale kit - http://www.geterbrewed.ie/american-pale-ale-extract-brewing-kit/

My questions are
- The recipe is based on a 23L boil, I have a 10L brewpot. How should I alter the recipe to allow for that? I was reading online and people were suggesting adding the second batch of LME with 15mins to go in the boil?
- Do I just throw the hops into the boil - no need for a muslin bag for the hops?

Yep, then top up with cold water to full batch size at the end.

Sure. When I brewed this way I used to pour to concentrated newly-boiled wort through a sieve into the fermenter to aerate it, then top up with cold water.

Cheers for the reply, so I reckon in a 10L pot the volume at start of boil should be 8L.

So my basic recipe is as follows

1. Steep grains in muslin bag for 30 minutes at 66 oC in 6L of water in brewing pot.
2. Remove muslin bag, let it drip then place into a sieve over the brewing pot.
3. Pour 1L of boiling water through the bag to get the rest of the goodness (I should have give or take 7L in the brewing pot)
4. Take off the heat and Pour in the first 1.5kg of LME - stir until disolved.
5. Put back on the heat and bring to a boil.
6. 60 Min - Add the hops to the boil at indicated times given in recipe (will be pouring these straight into the wort, no muslin bag)
7. 15 Min - Add the second 1.5kg of LME - stir until disolved.
8. 10 Min - Add the Whirlfoc tablet
9. 0 Min - Remove from heat and bring temperature down to 19 oC
10. When temperature down to 19 oC, pour wort into the FV through a sieve.
11. Top the FV upto the 5 gallon mark with water (Will buy Tesco water for this)
12. Sprinkle yeast on top of the FV when at 19 oC
13. Close lid and let ferment

(Not forgetting sanitation BTW)

I bought a muslin bag and hop pellets to dry hop but I'll cross that bridge when I come to it.

The recipe says OG of 1.045-1.060 & FG of 1.010-1.015, will this be affected by not doing a full boil?

aaronm13 · 14-10-2016 10:35am

Was just about to ask a question about pot sizes too. Going to move away from kits myself and want to start the mash kits from the home brew company

http://www.thehomebrewcompany.ie/hbc-dunkelweizen-mashkit-23lt-55-alc-p-1264.html

What size pot would I need?

Beer nut , would the stock pots from that place on Talbot St be suitable or are they too smal. Will be in town over the weekend and could pick one up then.

Let it cool (or dilute it) to about 60 rather than boiling. Water that's too hot will extract tannins, which you don't want.

Do you have a plan for doing this? It's easier to bung it into the fermenter hot, top it up and cool it as one process, and then even if it's still too warm it's not as big a job to bring it down the rest of the way. You want it at 27 (but no more than 30) btw. The initial higher temperature gives the yeast a boost.

Tap water is probably cleaner. As long as your tap water doesn't actually taste of chlorine it'll be fine.

VinylJunkie wrote: »

No, but if it's your first brew I wouldn't worry about the numbers anyway. When your readings are nothing like you expected, don't worry.

aaronm13 wrote: »

The answer to this question is almost always "the biggest one you can get".

I bought my 17L one there. It's grand. As I say: go big.

Makes sense so just run warm water through the bag / sieve.

Makes complete sense and makes things easier for me, cheers

So when I fill up the fermenter I should pitch the yeast when it's at 27 oC ish?I'm guessing the boiled wort + cool water will be near enough or above this temp? BTW The recipe says to add the yeast at 19 oC

I have a filter tap that I may use, just takes ages to pour from the filter.

Brilliant stuff, thanks very much!

No: fill it up, then pitch the yeast unless the temperature is still 30 or over, in which case let it cool to below 30, then pitch. Matching the ratio of wort to top-up water so that you finish with 23L at 27C is a real trial and error job. I'd just about got the hang of it by my sixth brew, which was my last using this method.

Lovely Bloke · 14-10-2016 12:26pm

If you mash the grain in 6 litres of water, you won't have 6 litres +1 litre sparge water at the end of that process.

The grain soaks up water and doesn't let it all out, when I'm doing all grain, full brews I usually calculate losses of about 1 litre per kilo of grain (so if I mash 5 kilo of grain in 18 litres of water, I'd expect to get 13 litres (give or take) of wort), then sparge with another 10 litres of 73 degree water to give me 23 litre boil.

Would you advise having a full kettle of boiling water at hand to pour in if the temp is below 25L as it reaches 23L?

BeerNut · 14-10-2016 1:00pm

Don't try and raise the temperature. 27 is ideal. 30 is too high, but if it's below 27 just pitch, it'll be fine: trying to raise it is more likely to cause something to go wrong.

You'll need a 30L pot if you're doing all grain mash kits from HBC

aaronm13 · 14-10-2016 1:20pm

Thanks beernut, might just have to get one online so. The homebrewcompany's ones are expensive but I'm sure they're good. I'll take a look at Amazon too.

Really? Was hoping I wouldn't have to get one that big ad storages space is going to bea problem, €64 too online.

Defninitely. Also think about how you're planning on heating it - an electric cooker won't be great - certainly ours wouldn't have gotten it close to a rolling boil. Haven't a clue about domestic gas.

You'll also need a chiller.

You could get a electric boiler or you could get the 17L pot and do 11L brews instead of 23L but you'll have to do your own recipes.

You'd have to be sure the base of the pot is of the right grade steel to work with induction mind.

BeerNut · 14-10-2016 2:30pm

I've never heard of anyone doing full-batch all grain brewing on a stovetop. If you're putting the effort in to doing all-grain, get a boiler. Or cut your batch size.

VinylJunkie · 14-10-2016 2:47pm

Sorry BeerNut, another couple of questions,

If I add the second can of LME with 15mins to go in the boil, should I take the pot off the heat so I don't burn the LME on the bottom of the pot or just stir like mad?

7. 15 Min - Add the second 1.5kg of LME - stir until disolved.

When the 60min boil is up, do you leave the pot off the heat for a length of time, or pour straight into the FV?

Cheers for tha. Think I might have to go back to the drawing board and see what I'll do. I'm only in an apartment so space is very limited. Thought I was good to go when I got a stock pot and my brother in laws mash tun. Any links to a suitable electric boiler. I have a gas hob to work off.

You should maintain a continuous rolling boil for the full hour. If you're concerned about burning, add the second can after you've poured the hot wort into the fermenter, then stir like mad before topping up.

The only reason to leave it sitting would be if you've done a big 0 minute hop addition. Otherwise, once the boil is over your immediate priority is getting the temperature down as quickly as possible.

You got a balcony? Most people do it there.

You could do brew in a bag if doing beers 1065 and under. Good video here

Thanks for the link and video. That boiler might actually be a better option and is the same cost as a pot. My gas bill would go through the roof boiling 20+ litres of water. So with this bolder and the mash tun I'm getting am I good to go or would I need the cooler too?

Unless you already have a way of getting 20L of boiling water quickly down to 30C you'll need a chiller.

To be quite honest I think you'd be better off doing 10L batches on the stovetop and just brew more often if output volume is the issue.

Yeah, I might just go down that road. I'll have to have a think about it. My brother in law must have a cooler so I'll check with him. Even if I did get those 23 litre kits I could just do 2 batches of 11.5 liters.

Not sure about that. There's no guarantee that you'll get the right proportion of grains in each half.

Surprised they don't have a 10L option.

aaronm13 · 16-10-2016 10:09am

Just reading through a few forums about cooling and came across something and would like some opinions as I'm a bit unsure. Say we take these 23 litre kits for example. If I was to boil maybe 13 litres of water for doing the whole process then top up with 10 litres of cold water in the FV at the end to cool. And also put the FV into a bath of cold water to help cooling. Would the addition of the cold water compromise the taste of the beer. I also saw freezing a 2 litre bottle of water and place in the pot or boiler to help cooling. I know I'm probably just going to have to do smaller batches but just wondering people's opinions.

testaccount123 · 16-10-2016 12:16pm

You know you'll need a 33L fermenter to ferment a 23L batch right? How is it you have the space to store a 33L fermenting bucket but not a 33L boiling bucket? One fits inside the other

I have two 33L and one 15L bucket that all fit into each other. If I get the boiling bucket this will fit into them too, no space issue there. My issue is unfortunately with the cooling as I don't have the space in an apartment to be setting up a hose. My kitchen tap will also not take a hose connection

VinylJunkie · 16-10-2016 11:25pm

Thanks for everyones help, I brewed it this evening, just waiting on the temperature to fall to pitch the yeast. The OG is 1.045 which is in the range for the recipe, tastes and looks very nice. Plan is to dry hop it next week.

VinylJunkie · 17-10-2016 9:29am

Is there anywhere to buy a 30L induction brewpot in Ireland?
