Homebrewing: In-Process Thread
So i was reading last night on here, that this year's ghost batch is different due to some hop changes and mainly a change in ph. Does anyone know the affects of the ph or when the change happens?

When i brew i typically aim for the 5.2-5.5 threshold. ARe the ph changes happening post mash? If so, i've never adjusted ph post mash. How does one go about measuring and doing this if required?


I personally have no idea what Andrew is talking about with Ph impacting clarity of this new batch. On a homebrew scale, I am worried about mash ph for efficiency purposes. I am going to have to do more research about this ph impacting clarity. It could impact hop character I suppose but that is over my head. I will talk to some chemistry guys and get back to the board

Yeah, i'm more interested in how it reacts with the hops, not so much on clarity.

I had been drinking when it was explained to me.

Basically, the higher pH in the mash didn't allow certain proteins to fall out, causing a chill haze.

But people a lot smarter than me will have to explain it.

I just read up on this. It has to do with the boil. a lower ph of 5.1 allows the proteins to fall out quicker.

same here. So the ph thing only had to do with color?

In theory (and simplified)....

Mash and Kettle pH can affect hop utilization and protein coagulation in the hot and cold break, both should be somewhere between 5.2-5.5. Lower than 5.2 and you start to affect hop utilization, Higher than 5.5 you can have problems with color (darkens during boil) and protein coagulation.

A lot of residual proteins can be dropped out using gelatin, but gelatin and fining agents can also bind to hop oils and pull those out of solution too.

IMO: Just add more citra and enjoy your hazy IPA.

Tried the wife's Lemon Basil Wit over the weekend, it really came out nice. 4.7% with a good haze to it and just the right amount of lemon and basil to taste it without it being overpowering. She really did a good job with it.

Anyone here use Motueka and/or El Dorado Hops?

I'm fine tuning an ipa recipe using mostly El Dorado hops, with some Motueka as well, and a little bit of Amarillo. Someone told that El Dorado is a gentle hop. I'm worried about the amarillo overpowering it.

Hop Bill - 91 ibu's

1.2 oz El Dorado - First Wort
1 oz El Dorado - 20 min
1 oz. amarillo - 5 min
1 oz. motueka - 5 min
1.8 oz. el dorado - whirlpool/hop stand
dry hop
1 oz el dorado - 5 days
1 oz amarillo - 5 days
1 oz Motueka - 5 days
1 oz el dorado - 3 days

I'm thinking the orangey quality of the amarillo may overtake the profile i'm looking for (stone fruit, with hint of lemon/lime). I'm thinking of maybe subbing in citra for amarillo or maybe eliminating amarillo and upping my el dorado/motueka quantity.

El Dorado did nothing for me when I dry hopped with it once. Had to put some Citra hops in the keg to kick it up a notch.

Haven't used Motueka, but had the single hop IPA using it from Courtyard. It didn't wow me. Scott said he has no desire to use it again, so take that for what it's worth.

I made an all El Dorado pale ale once that was very unimpressive.

dammit. I had the entire recipe all laid out. Wanted to try some new hops i've never used before. I guess it's back to the drawing board.

well try it. I used them before I used the correct water, before I was aware of the effect of ph, and in an extract beer that I bottled, and none of my bottles every carbonated right, it was too much or too little.

Looking back at the recipe, I should have used more. I only used about 2 ounces in the boil in 4 seperate additions and the beer was only a calculated 48 IBUs

Well, i'm doing some reading and a lot of the comments on homebrewtalk is that it is very mild. A lot of hops equals minimal presence. I'm still resesarching.

ETA: I think i'm still going to brew the recipe. I still want to find a replacement for Amarillo. Something more subtle.

Bug, here is a description of one of Maine's beers:

quote:

A tiny beautiful something showcases a new hop variety, El Dorado. We started playing around with this hop last year. We brewed a pilot batch with this hop exclusively and one with it blended with some of our other favorite Northwest varieties. In the end, we decided that the El Dorado had such a unique and interesting character on its own, so we decided to brew it as a “single hop” pale ale. The aroma and flavor offer intense candied orange and citrus zest. A touch of flaked oats provide a rounded, silky mouthfeel. And like our other hoppy offerings, tiny was brewed to finish dry and clean.


you can read the reviews of it here
