Default 30 minutes?

this recipe i got for an extract brew only calls for a 30 minute boil, with hops going in at the beginning, then 8 minutes to the end and then the last minute. is a 30 minute boil accurate? im just a little confused because ive never heard of this before

It's certainly possible. Boiling for 30 minutes means you might get some hop flavor as well as bitterness coming through, but it shouldn't really hurt anything, assuming that 30 minutes is enough time to extract enough bitterness. I've deviated from the standard 60 minute boil several times with no ill effects; for instance, I did a Kölsch with only a 40 minute boil and it turned out great. Just out of curiosity, what style of beer is it?

Most of my extract kits have had a 60 minute boil but just as "jar1087" experienced, my Kolsch used a 45 minute boil. I've also read some other extract recipies that have shorter boiling times.

would a 30 minute boil really be a good idea for a bitter, or should i just deviate from these instructions a bit?

What are the alpha acid % and weight of your hop additions and what IBU are you shooting for?

im too early for the alpha acid % and IBU thing, Im not exactly sure what they are, but the hops are listed in the ingredients as follows

1 oz Northern Brewer Hops (boiling) 30 minutes
0.7 oz Fuggles Hops (flavouring) 8 minutes
1.5 oz East Kent Goldings Hops (finishing) 1 minute

Personally, I'd boil 60 min.; especially if you are expecting an Original Specific Gravity (OG) of 1.050 or above. Add the NB at around 45 min, the Fuggles at 10 or 15 before flameout, and the EKG at the 1 min mark as directed.

But that's just me.....

No actually not, just the opposite.

Bitters are low grav/low ibu beers ("bitter" as a name is a misnomer, most of them are very balanced or even more malty than hoppy imho) so it makes perfect sense that an extract bitter would have a shorter boil time; you don't NEED the extreme bitterness that a 60 minute boil would do...You don't have to worry about a huge isomerization of the alpha acids.

I'm noticing that a lot of low Ibu extract recipes are going for the shortest boil possible these days, just enough to extract any alpha acids from hops and to steraliize the wort. I'm thinhking this may be another brewing culture shift...which may be a great thing for lighter beers, a shorter boil means less carmaliziation of the extract and may make for lower srm extract beers.

So I would stick with the recipe in this instance....if it were an IPA, I would have a different take on things.

So Revvy, you think I should just do the boil as per the instructions at 30 minutes?
