Distilling hops
 
Humans have been dis tilling plants for concentrated oils for literally millennia.

I'm thinking of distilling some hops to make IIPAs easier to make. Because:

A) Dry hopping tastes freaking awesome, losing beer to the hop mess sucks.
B) I can keep oil much easier than lots of hops hanging around. Freezer space!
C) no hop bags.
D) it sounds cool


I have never done it before but I have distilled, um, water and vinegar before.

Would it work the same?

I've also thought about using ethanol to extract the hop oils and just add that to the carboy, but I don't know how much oil can dissolve in the alcohol and dont want to make it too boozy.

Curious about this as well, since some of the big name breweries (Miller in particular) uses a hop extract (for lack of a better word, im not sure what exactly its called) instead of straight hops for making certain beers such as their High Life.

Hop oils are typically done by supercritical co2 extraction. Typically used for bittering, even in commercial examples like pliny or hop stoopid. Not sure how effective they would be for dry hopping since theyre very viscous (wont disperse in cold beer) and also when dry hopping youre trying to infuse the beer with the essential oils. The oils are very volatile so its not likely you can extract them using a typical distillation.

Do some searches on the net for essential oil extraction and you'll come up with some good finds. PM me if you want a few links to forums that can answer your essential oil distilling questions as this forum frowns upon distilling talk. Yes you can absolutely remove the resins. Its a fairly long process but your normal pot still will not do it very well.

Cheers

Distilling oils, along with water and vinegar, is perfectly legal in all states and Canada; I don't see why it would matter to talk of such things here... I'm proposing a legal process to make better homebrew.

Would I make a tea first? How is it different from distilling vinegar?

Ohhh I know.... As do others for sure. I was just giving you the heads up, just in case you didn't know...

Cheers

Thanks, Jay.

I did some searching and it looks like there is one more leg to essential oil distillation than water or vinegar distillation.

Apparently you have to steam the plants and then distill it and condense it in cooling hoses per usual.

It looks like the by-product of floral water in my scenerio might be a version of hop tea. Wort water anybody?

If my previous experience with vinegar is something to go by, it looks like this might add another full hour to the brew process, though it could be done a different day of course.

A little bit confused by the picture I your proposed process. Does the distillate go into a decanter and then separate into an oil fraction and a water fraction? You didn't mention it specifically in the post so I just wanted to make sure.

It will be an interesting flavor difference I think compared to conventional dry hopping. The other interesting thing I'd that if you get good at this, you are perfectly setup to make a killer clone of Ballantine No.1 according to recipes Ive seen. I think you will just have to find, I think, bullion hops.

There are varietal hop oils but I don't exactly know how you would get it to disperse into the beer. I have a feeling its pretty viscous. It'd be interesting to get some and add it to a batch like with a priming solution. For all we know that might be a technique used by some of these breweries that bottle condition. I could see adding a portion of beer to their bottle conditioning system along with a varietal hop essential oil dose. Then that is dosed inline to the filler.

I think so. The oils should separate from the water and float to the surface.

If, however, hop oils have a higher volatility than anything else, it would seem that once condensed in the cool water, one could simply collect the first runnings (heads) and keep them separate from the floral water. Then, use the floral water as wort!

This is a bit different pic From this cool article:
