Anyone brewing Brut IPA?

[couchsending]

If your gravity ends a little high you can always add more enzymes at the end. I’ve actually naturally carbonated a beer doing this instead of adding sugar. It was just a small experiment that I kept cold in a keg but it did turn out great. Wouldn’t do it with bottles unless it was thick glass.

Just FYI, for anyone using the FermFast Glucoamylase (10g)...I did 3g during my sparge (batch sparge with room temp water, so temps were not an issue), then I added the remainder of the enzyme during chilling once the wort was at/below 130*. Pitched US-05. Dropped from 1.052 to 0.999 in 3 days. Monster.

View attachment 581508For those of you that are using this 10g pack, how much did you add for 5 gallons? Also did you just mix it with warm water? I plan on adding it to the fermentor.

I added the entire packet as fermentation started slowing around day 3, waited a few days and FG was right on the dot at 1.000
added a 3oz hop charge waited 3 days FG hadn't changed
cold crashed 2 days
kegged w/ 40psi for 24 hours
reduced to serving pressure yesterday
Ill draw a pint tonight and report back

EDIT: I added the packet dry and gave the FV a swirl, used US-05

Tasting notes?

Stand by! I didn't get to taste the hydro sample the other day, I was in a hurry and it was full of trub and hops. I'm transferring to a dry hop keg this weekend and will taste then.

 

[WiscoBrewer]

Kegging mine right now, damn is it friggin dry. I hate to say but I might not like this style too much...we’ll see after carbonation. I’ll be hitting it with the QuickCarb shortly.

 

[dschiller]

The glucoamylase is the one that will chop dextrins down to glucose that the yeast can eat. Alpha amylase cannot chop up dextrins. It's the elimination of dextrins that enables the very low FG's in a Brut, since dextrins are not fermentable.

Brew on

You should be able to use either, right? According to the above, Kim Sturdavant’s advice is to add amylase enzymes to the fermenter (although I also read that he puts it in the mash). I ordered the alpha amylase to use in a week when I try this for the first time, so I’m hoping it will work. Perhaps the main difference is how long it will take to convert all the remaining sugars?

Oh...I just realized he didn’t say to use alpha amylase. In fact he says he uses:
Amylo[emoji769] 300, which is an amyloglucosidase enzyme.

I just ordered the Fermfast glucoamylase and I’ll save the alpha amylase for making bread.

Ok, I have been drinking on the keg all weekend. The dryness is interesting for sure, I wasn't sold on it at first but now that it has had a week or so in the keg I am really starting to enjoy it. I wouldn't say it is exactly quaffable, but it is deceptively strong.. I'll put back two of these pretty quick because they are so light and crisp, stand up and feel it. I do like the concept of a lower OG still resulting in a 7+% beer. Because of the higher carb levels, I am keeping my fridge around 35F which does seem to mute the flavors of the hops slightly. I didn't do two dry hop charges in the fermenter and next time I definitely will.. I think I might just toss a few oz in the keg and see if that increases aroma. I did a 3 part combo with Bravo, Mosaic, & Cascade. Overall the hop flavor is good but a little light I would like to bring it up a bit in the future.
Hop schedule looked as follows:
Bravo 0.5oz @20
B, M, C WP (1oz each)
B, M, C DH on Day 4 (1oz each)

Aroma: Definitely a hoppiness, some citrus and the slightest hint of tropical fruit
Taste: Super crisp, definitely get the cascade citrus and similar to the aroma a slight fruity backbone. You can definitely get that it is dry, but by no means is it off putting. I definitely understand why some call it "hop champagne" but I must say I like the brut a hell of a lot more than champagne..

This is quite decent and I am curious how it will age while drinking. I would definitely like to keep experimenting with this style and surely will

I was finally able to get my first attempt at this style going last night, and the yeast are happily chugging along. When I went to add the Ultra-Ferm, I noticed something odd on the back (see picture) - in the "Temperature" section next to ultra-ferm is says "Up to 185F (85C)". From everything I've read, this enzyme would denature very quickly at temperatures that high, assuming it is actually amyloglucosidase as White Labs claims. Does anyone know what is meant by this? I'm expecting everything will turn out fine, but this struck me as odd so I wanted to see whether anyone knew why White Labs would list such a high temperature for this product? I'm using it in the fermenter, so obviously nowhere near 185F, but still curious.

 

[brew703]

I brewed my version this past Friday. Fermentation is still going but not as strong as Saturday night through yesterday. I'll probably take a gravity sample Saturday or Sunday and if close or at 1.000 I'll add my dry hops (citra & mosaic).
Getting a little anxious to see how this turns out.

 

[jaymosbeershack]

Just added some enzyme to my mash. Officially brewing a style i've never tasted. Gonna split off a gallon and add some peaches, aim for a beer bellini. Thanks everyone in this thread for all the info

 

[TravelingLight]

I kegged mine last week and am drinking it now (well, not right now). I like it. It's dangerously chuggable at 7.1%. But I don't know yet if I love it. I think I want more hops in the nose. I did a double dry hop with 3oz in each dry hop (and a 3oz whirlpool in the kettle).

Didn’t clear up and didn’t like it much at first, but after sitting a cpl weeks it’s fantastic!

 

[ProblemChild]

joining to follow - had my first Brut IPA last Wednesday. Fantastic.

Same. Mine was better a week or two after first tapped. I had troubles clearing mine up as well - chalking that up to the large dry hop charge.

 

[Northern_Brewer]

For those whose heads are spinning at all this talk of 1-4 and 1-6, there's a nice explanation of all the various enzymes in wort from p25 of this new MSc thesis from Tom Shellhammer's lab which is mostly looking at enzyme activity in hops.

 

[stickyfinger]

did a split batch brut ipa. added enzymes to the wort when it was chilled to 135ish after boil for like 30-60 mins. went from around 1.050 to around 1.0001. one had huell mellon in the dry hop and one had mosaic/ctz. both are very nice. i don't really get a super dry character though. i would think they are maybe 1.010 from tasting them. weird. i did like 150 ppm sulfate with minimal bittering.

 

[cheesebach]

My first brut is getting kegged tomorrow - it's crash cooling now and already carbonated about 90% of the way, so I should be able to get my first taste this weekend. Mashed at 152F, added enzyme to the fermenter at 8 hours after pitch and went from 1.055 to 0.999 (as measured by my Tilt - will take a "real" reading tomorrow). It took about 6 days to finally get there though - it was at 1.008 at 72 hours in and then slowly made its way down to 0.999 over the next 3 days. Went Mosaic/Nelson/Citra for whirlpool and dry hop with just the tiniest bittering charge at 15min in the boil. I haven't found anyone here in Austin making a legitimate "Brut" yet, so this will be my first experience tasting one and not to sure what to expect. Good or bad - it will be interesting and I'll learn something new!

I'm in the same boat. I will be kegging mine today. First taste might be Sunday. Finished at .997. Never had a Brut IPA so this will be the first. Sample tasted pretty good so have high hopes.

It's interesting he mentions WLP644 and WLP026 Premium Bitter Ale as possible POF- diastaticus strains. Suregork found a STA1 gene in WLP026 but White Labs make no mention of it as a diastaticus risk (which is something they're quite hot on these days) and list its attenuation at 70-75% which suggests the STA1 is not active.

Interesting. I'll bet taking out a portion of the wort after five to ten minutes and rapidly chilling it down would work best.

Would be good to know how much of the raw wort would be necessary to provide a sufficient amount of enzymes.

[stickyfinger]

my hall blanc is weird. i think i overdid the dryhop. 1 oz/gal. maybe it will age well. it’s just a very unique hop flavor!

 

[cheesebach]

How low can you go? Looks like there’s no stopping this enzyme when you give it a week or more to work in the fermenter. The temp-corrected reading for the sample below is actually 0.996 so not quite as low as it looks, but the OG of 1.055 puts this one at 7.7%. This was the sample from the fermenter, so I’ll have to wait a few more days for a real taste, but my first impression was that it wasn’t necessarily sweet, but also not that dry. Gonna have to be careful with this one...

 

[jomebrew]

I kegged and carbonated my version inspired by the Social Kitchen recipe. I used a generic amylase enzyme from BSG. I will definitely do this again.

Below is my recipe and brew notes.

** I used rice extract instead of flaked rice as my LHS didn't have flaked rice.

6.6% ABV
60 IBU

Really happy with the result. I am not sure I would like it as much with a lower final gravity.

Can anyone comment on 1-4 enzyme vs 1-4 + 1-6 enzyme with regard to FG and body & flavor differences?

I bought some 1-4 enzyme hoping to dry out a beer (it's at 1.004 without enzyme) and I'm wondering if I should spring for something else.

The 1-4 enzyme will not reduce limit dextrins to fermentable sugars, so you will not get the maximum "dryness" or lowest FG.

That said, my 0.996 FG brut had more body and mouthfeel than I expected. I assume that it is all due to the late/dry hops.

Brew on

 

[jaymosbeershack]

Got mine carbed to 16 psi so far(working toward 20) fg was 1.001. The first sample is quite good. Cant wait to try it at 3.2 volumes

 

[Cede]

I did not try this new style yet but I find it interesting and reading the recipes and comments is tempting.

I have the amylases as I use them for some other beverages and I think I will try a mash whisky style and see where it goes.

 

[jaymosbeershack]

Fully carbed and i love it. The Azacca almost gives it a mimosa character. Nice and dry, but not astringent. Cant wait for the next batch.
