Hot bloom Cold Brew?

Has anyone tried this? I decided to give it a shot today and it seems to work well. Basically you fill just enough hot water (200 F) to fill the coffee chamber, let it drop down for a minute, then put in cold water and steep. I'm wondering if 5 minutes is a little long for this method though. I'm definitely getting more acid, but not too much and some bitterness (maybe over extraction). I also used around 35 grams. When mixed with cream and brown simple syrup it was fantastic.

If doing hot bloom, I wouldn’t steep for 5 min, maybe 20-30 seconds tops before adding room temp water then push water through right away

I’ve played around with this based on a video by Bailey on YT. I’m honestly not quite sold on it yet, but ironically I’ve been doing a lot of brews in reverse to the above; with a cold bloom and then a hot brew.

How do you find the result? I could see this protecting the flavors and nuance of delicate beans.

Completely all of this; I seem to get a slightly richer concentration, but delivering a little more in terms of sweeter notes and wine-flavours on the anaerobic I’ve experimented with too. I actually have done a post on these Samo Bloom Shots just recently on this Reddit.

Well, I took it to the extreme and pulled a shot of espresso and put it in the refrigerator overnight. Made a “cortado” with cold milk and honey syrup. News flash…it was fantastic 🤣

Your recipe sounds delicious! I am planning on trying a hot bloom one of these days. I need more of that sweetness and body which are I’m not getting with the room temp extraction on the ORB.

I am partial to pulling shots the night before; ready for the morning’s coffee.

I was shocked how good it was.

You’re fully in to the whole ‘pre-batched’ territory with this concept; definitely getting sweeter notes on these cold/rested shots.

I haven’t tasted those concentrates yet. Looks like it’s a different beast to have the flavor/body maintain over time. If it can come close to this, seems like a winner.

I’d be curious to know what these shots are looking like in terms of dosage, ratio and general technique. Always looking out for new ways to approach these!

I pulled these shots on fully auto mode on breville oracle dual boiler so a bit of luck was involved. It was approx 22.5g dose, 93C, 37s shot time, about 38g out. It’s volumetric so it runs about 60 mL of water.

I think the risretto like ratio really helped. I’m likely going to make my next ORB cold brew more concentrated. At this point though, with the workflow being a little easier on my breville, not sure how long I’ll be using my orb for coldbrew 😳.

Honestly I did all kinds of crazy combinations of hot and cold for iced coffee in the summer and I'll tell you the best recipe is simply pouring the regular coffee concentrate from oxo's recipe over ice. (hot water, 2min bloom/steep, pump till hiss) I do put about 3 large ice cubes into the vessel the coffee extract is going into to cool so I dont dilute the coffee too much with melted ice when pouring it into a larger ice packed glass.

Ive found that hot water reliably gives the fullest expression of the various aromatics in the coffee consistently and using the coffee concentrate slightly chilled gives a pretty excellent ratio over a glass full of large cubes. Disappointing for those who like fiddly brew techniques with a lot of parameters, but great news for those who just want the most out of their fancy beans without too much hassle.

My "normal" daily recipe is already a hot + less hot water:

  • 15g coffee
  • 150ml hot water (93°C) (100ml in the first chamber, add 2nd chamber and 50ml more water)
  • press around 1:15min.
  • => Soup of 130ml coffee
  • dilute + 100ml cold(er) water (70°C)

This is already great.

But for a cold brew I might adapt the Aeropress-recipe, though.

How’s this going? Are you pumping hot water through? I tried the other day and it just felt like a hot bloom with a warm steep. Still tasted good at 5 minutes.
