A couple of questions that I have had for a long time, but finally took the time to write down. Would love some help with these.
- A majority of pro brewers do not cool their wort after the boil and before adding hops flameout hops. I know this is an area of interest for some breweries, but not everyone is equipped to do this. The hops sit around for a long time at high heat due to the thermal mass of the wort and the time it takes to cool the wort. I’ve heard from some pros it takes an hour or more. Why is it that the neipa community has adopted whirlpooling at say 160F or so and then letting the temperature decay over 20-30 mins. If we are trying to replicate the beers from pro breweries, shouldn’t we be whirlpooling right at flameout and maintaining temp? Lower temps do not isomerize all those awesome hop oils which makes sense, but like I mentioned, aren’t the pros isomerizing them?
- A lot of recipes seem to suggest killing the flame, throwing in some hops, and begin chilling right away. What’s the advantage of doing that if you are at isomerization temps for like a minute before you are cooling already and down a significant amount of temperature?
- Dry hopping. Some pro brewers I hear on podcasts and such talk about the importance of crashing out yeast before dry hopping. It’s known that yeast pulls hop oils with it so the more yeast you can get out the better. For us homebrewers that don’t have cool conincals, this is an it hard to do without oxidation. However, at the same time, another contingent of brewers discuss the importance of dry hopping at fermentation temps, at the very tail end of fermentation to allow yeast to scrub any introduced oxygen. Is it just a meter of preference?
It's definitely an interesting discussion.
but in the interest of homebrwing, i suspect we do what we believe works bestfor our own systems, but it would be an interesting experiment for someone to try out.
In other news, i got hold of some Dry voxx kveik from lallemand, so did the below.
1.065
4.3kg pilsner
1kg pale male
1kg flaked oats
1kg wheat
200g acidulated for ph
chucked in the following at whirlpool
2 oz amarillo
2 oz azacca
1.25 oz riwaka
1 oz centennial
gave it 30 minutes and then rack into my bucket.
pitched a day 1 dryhop of 1oz centennial
with another 2.5oz at 48 hours in.
2 packs of voss kveik - unhydrated (i've been told to try it without rehydration on kveik dry strains).
then on day 5/6 the final dryhop of 3.5oz mandarina bavaria & 1.5oz loral.
will be interesting to see the difference between kveik and other strains for me, having not used it before, i tried the NEIPA lallemand strain recenly, and wasn't impressed, but keen to try london esb as a dry strain into a hazy. Has anyone tried it?
