Brewing With Beetroot

[Malnourished]

(Apologies for cross-posting this, but I'm really keen to show off my new Imagestation skills :lol: )

A while back Neonmeate brewed a Beetroot Brettanomyces Barleywine which I was lucky enough to be able to taste. In a discussion on another board it was mentioned that when you mash beetroot the resulting beer loses the colour. Neonmeate's beer was the colour of blood, but he added the beetroot to the secondary, so I was keen to test it out.

Anyway I got around to finally brewing this beer on the weekend and it's true! The runoff was a beautiful beetroot colour, but after the boil it had changed to more of an orangey-pink, kind of like that Schweppes Agrum soft drink. Weird.

I took some photos which can be viewed here

Anyone have any idea why this would happen? I wish my beer was still purple

Jeez - I got stick for putting bananas in my beer :blink: ... I can't stomach beetroot at the best of times, what does it add to the beer??

Guess it must have been good if making after trying someone elses ...

Sorry, don't know the answer to the colour question - looks nice though...

The technical answer would be that it's doing something funny to the anthocyanins, I imagine.

 

[Tseay]

From my research, the answer probably goes along the folllowing lines:

The red colouring in beetroot is the result of two pigments. A yellow agent
( Beaxanthin) and a purple pigment (Betacyanin). These pigments stabelise in acid conditions, which is why beetroot is often pickled.

"Betacyanins are fairly stable under food processing conditions, although heating in the presence of air at neutral pH values causes breakdown to brown compounds. The colour of betacyanin solutions was stable at low temperature. Half-life at 25 oC is 413.6 min vs. 83.5 min at 60 oC"

So in a boiler for 70 minutes ( although an acidic environment) you can imagine the purpule pigment would be going south quickly. It would seem the more the purple pigment breaks down the yellower the mix should become.

It seems to me that what you've experienced is what you would expect and your friend's result (ie intense red) seems to be unusual. Unless of course he was using some other source of colour. eg crystall etc. alternatively was the big difference in boil times ?

Also it appears that the ratio of red to yellow pigment varies between species of beetroot.

Guess it might have something to do with the fact that Neomeate added to the secondary not the kettle ...

 

[Malnourished]

Wow! Thanks Tseay! Great answer.

Geez Ross, you must be nuts putting banana in a beer. That's crazy! Actually I figure the beetroot is just a source (a very inefficient one at that) of basic starches. I don't expect it to taste strongly of beetroot, though a subtle touch would be nice. I really wanted to make purple beer though...

 

[neonmeate]

it was already quite a dark barleywine - sort of mahogany-brown. adding the beetroot though made it go incredibly rich red with a bright pink head! perhaps the acidity added by the brettanomyces "pickled" it. or perhaps the 12-14% (i have no real idea but it's high) alcohol preserved the colour too.
i didnt boil the beetroot - i cooked it (baked with the skin on so as not to lose liquid) then mashed it up and threw it in secondary, then racked it off to bottle after leaving a couple of months for the yeast to get through the extra sugars.

i liked the taste but then beetroot is easily my favourite vegetable! the earthy sweetness matches rich malt really well IMO... i also make a chocolate and beetroot cake which has to be eaten to be believed.

i'll have to try it again one of these days...perhaps without the brett...

 

[neonmeate]

just an idea, er, "mal", did you cook your beetroot?

 

[Tseay]

Apparently if the skin is left on during cooking it will maintain the cell integrity and minimise leakage of the pigments

Well you can beat an egg, but you can't beet a root!

Beetroot?!

We'll have to call you Bert Baxter NM.

(Anyone ever watch the Adrian Moll series on the ABC?) :unsure:

yeah i used to watch that but i don't remember a lot about bert baxter (beer has dislodged a lot of other stuff in my brain). did he like beetroot? or do you just like alliteration?

 

[Malnourished]

Yep, but I boiled them in water, then chucked the whole lot in the mash. Didn't you look at the pictures????

Care to share the cake recipe?

doh, thought i had to sign up for a username to look at em.

well you might have lost a little bit of colour boiling them up already peeled and chopped in the first place but it looks as though the runoff was a nice colour...

what i don't know (having no idea about biochemistry) is how the cooking affects the starches? i know beetroot has a high sugar content but how starchy is it? does it in fact need to be mashed? i wonder if throwing them in secondary left some starch around which caused the gusher that wrecked your carpet?

cake is something like: flour, baking powder, eggs, cocoa powder (or melted chocolate), vegetable oil in normal proportions for a chocolate cake, then add i think two medium beetroots pre-baked for 90 mins, peeled and mashed to mush. cook the cake. cool. eat with king island double cream. or a nice thick natural yoghurt.

How can people not love betroot goes great/u beaut on a burger.

My understanding is that baking won't convert any starches (like how all those Yank pumpkin ales mash the pumpkin after roasting) but I could be wrong. Starches + brett in a bottle is a sure-fire recipe for a gusher I reckon, but perhaps after 6+ months in secondary all the starches would be eaten up? Secondary sure seems like the way to keep that great beetroot flavour. I reckon a brett beetroot imperial stout done that way would be pretty grouse. And it didn't wreck the carpet - it came straight out. I was shocked.

cake is something like: flour, baking powder, eggs, cocoa powder (or melted chocolate), vegetable oil in normal proportions for a chocolate cake, then add i think two medium beetroots pre-baked for 90 mins, peeled and mashed to mush. cook the cake. cool. eat with king island double cream. or a nice thick natural yoghurt.

Ta. Sounds a lot like something I do with bananas (there ya go Ross!) Don't think it'd go all that well with beetroot saison though, sadly.

Old Bert was always munching on a jar of pickled beetrot. As witnessed by the staining around the top of his shirt. :blink:

Bert Baxter broke his bowels bottom burping beetroot. :wacko:

Just let it be known my alliteration sucks arse. :lol:

bert baxter brewed and bottled a big batch of brettanomyces beetroot barley wine. boom! the bottles began to burst. "bugger!" he bellowed belligerently, bending to bin the broken bits of beerbottle.

looking lively lying lovingly on lino licking it up.
