Boiling

[Maeldric]

Hey guys i have a quick question about boiling. Lets say you wanted to make a 50L batch of beer and you are doing an extract brew. If you only have a pot that is about 15L in size if you did your boil of hops and malt extract in that and then added the rest of the liquid straight to the fementer would you get the same results as if you had done the whole 50L boil? Thanks in advance.

I think the whole boil beer will be slightly better. I've found that boiling will drive off a lot of the telltale signs of additives in tap water.

Where I live, the tap water has a smell and a taste that makes you certain there's an amount of something in there, it's not just aqua pura. This taste persists through a partial-boil beer, but doesn't with a full boil beer.

That's not to say that the partial boil beer will be undrinkable, but if you actively loathe the way water tastes out of your tap, you'd be better off doing a full boil.

Hi Maeldric

Palmer says that in order to get the right hop utilisation (he might call it isomerisation or something) the gravity of your boil should be similar to the gravity of the final wort.

I am doing a similar thing to you, except I am doing 22L batches from a 15L pot. So in rough terms, my boil wort (7-8L) is about a third of the total wort volume (you want to leave a bit of room in the pot for foam and the like), so I add about a third of the malt extract bill for the full boil, then add the rest of the fermentables in the last 10 minutes.

hope that helps.

Wardhog I would still use all boiled water in the fermenter i just do bits at a time seeing as my pot is so small hehe. Just wouldnt be able to do it all with the hops and extract at once. Thanks for that insight Earl, given me something to look into now.

Apart from low hop utilization, a more concentrated wort in the 15L boil will promote maillard darkening in the final beer. So your beer will be darker than if you did a full volume boil.

Also, even if you are topping up with water later, for sanitation reasons, you should make sure that the top-up water has been boiled at some prior stage.

Ummm wouldn't this be no different to making a kit beer when you add the water. You don't bother with "sanitising' the added water in that case. Why would it be different in this case?

Bingo! Not to mention that the water out of the tap is 'drinking' water. How many ppl is Oz die from drinking tap water? HTFU

Sometimes ppl make a habit of overthinking things.

I'm not quite sure, but as soon as I moved on from kits I suddenly felt the need to start doing that, not sure itll make any difference (Apart from the taste thing mentioned earlier)

Probably noone, but that doesn't mean there no bacteria in your pipes/taps etc.

Not trying to overthink, just know there's nothing worse than wasting a batch of beer because of a simple precaution you could have taken.....

HTFU????
