No boil brewing.......

South Coast Brewer · Jan 11, 2020

Just about to try my first no boil brew, a pineapple and mango no boil recipe tweaked to my liking from the David heath original and scaled to my GF 30. Anyone else here a regular no boil brewer? I like the idea of using this method (if it turns out well of course........) to squeeze in a brew day when time may be limited. Looking forward to using omega hot head yeast again as well, always liked the results from this strain.

I do some no-boil extract brewing with good results.

I did a no-boil wheat last summer the fermented with Voss, it was really good and is still decent 6 months later even though the hops have faded. I'll probably do this again over the summer when it's too hot and there's too many wasps about to brew comfortably.

How do you utilise the hops in a no boil? Extract?

@BeerCat is the forum no-boil-meister. I think he does all his brews no boil and has done for a while

Don't you get undesirables with not boiling the wort? Like DMS?

Also does spraymalt need to be boiled, as I haven't boiled extract kits, just followed instructions, and beer enhancers contain it?

Hop isomerization starts around 185f (85c) so you can get bitterness without boiling.

Extract is boiled in the manufacturing of it which is why "no-boil" kits work and DMS is not an issue.

Never heard of no boil before. Would be interested to hear some of the results peeps have had. I am mainly a 20/30 min boil guy. As @MrRook says, bitterness starts extracting before boiling temp and continues to be extracted after flame out, unless you are seriously chilling your brew almost immediately. I find the 60 min boil unnecessary for the most part. I tend to boil closer to the 40/45 min mark if I am going for a beer with a high IBU content but when I say high, I am talking 70+.

I boiled 1L of water on the stove for 20 minutes with enough hops for the IBU I wanted. Then I added this after sparge along with the rest of the hops and held at 80c for a while (away from notes) to pasteurise and let the hops soak.

So, technically not no-boil, just no wort boil.

True enough I guess. But the wort not being boiled is the important bit for the beer. Also it's a lot easier (and less steamy) to boil 1L on the cooker for 20 mins than booking 20-28L for an hour.

The basic brewing radio guys do a hop sampler every so often, it's extract and they do boil but all the hops are added post boil and they get plenty bitterness, I want to say they cool to 80c before adding them which would be the same as the no boil steep.

Found this for those who wish to learn more, rather than sticking red hot needles in their eyes. Think I may give it a go, commercial breweries dilute and add the hops post fermentation, just have to work out how much extract to add. 15 mins held at 85 C will give a beer with a 12 week shelf life, more than enough.

Just watched this on no boil -
Think I may try it if we get a hot summer.
Interesting he used kveik yeast.- and screamed at it. Apparently that is a thing. clapa

In the pdf foxy linked to it was saying kettle hop addition would be better at 10% of normal rate for bittering, so maybe leaving more for dry hopping later?

Learning new stuff all the time here. Thanks. athumb..

I have an American wheat conditioning in the bottles which is no boil.
I heated the wort to 80 degrees and banged in 100g of hops and left to cool then dry hopped with an 150g of hops.
Hopefully I will be tasting it in a week or so.

I recently did a scaled down to 12 litres totally tropical (James Morton) no boil. Basically followed @BeerCat thread and more or less same way as @Zephyr259 mentions above. No issues with the beer, tastes great, everything went well other than the og was way down on what I'd calculated, think about 8 points from target. To be honest, the beer tastes great so not too bothered about the ABV.

planning to make a hop tea and add to the keg before my closed transfer, also dry hop for aroma. Ive also got fruit going into the FV at 4 days so there`s alot going on! Cant wait to try it!

DMS becomes volatile and will start to evaporate off once the wort reaches 75 degrees +, planning on keeping the lid off during the process allowing maximum surface area exposed to help with this. It`s an all grain recipe so not sure about extract i`m afraid.

I did a no boil wheat in the summer and I was disappointed. Found the rest of it quite recently and it's improved immensely.

Does no boil beer need longer conditioning time
