Minimum boil time for LME and steeped crystal wort?

[lancsSteve]

Just wondering what minimum boil time could be for extract beers?

For all grain (which I used to do all the time but now time and kids mean when I rarely get to brew it's extract) you obviously need a good hour's vigorous boil to drive off volatile compounds and get a good hot and cold break for clarity. But what about with processed malt extract?

Anyone got experience or warnings of minimum boil times - I'll be using protafloc for clarifications and working with IPA type recipes so almost all the hops go in really late i.e. 15minutes or so.

Planning 2 brews tomorrow both based on pale LME - one with a bittering charge of dry first gold, then lots of late hopping with home grown first gold hops in last 5 mins and a long 80c steep added, the other also with some steeped paler crystal as well as palm sugar then 200g of Sorachi Ace and 100g Pacific Jade in total in a late charge, 80c steep and dry hop.

Wondering how long I'd NEED to boil them - can you get away with 45 or 30minutes for example?

This https://byo.com/hops/item/10-10-steps-t ... ct-brewing still points towards 60 minute boils - is that real minimum then.

15 minutes at the boil is fine. Most extract has already had the nasties driven off by the extract producing process.

Extracts are boiled in the manufacturing process and don't really need to be boiled, which is why no-boil kits work.

Cheers, thought so but wanted to check!
