General Homebrew Discussion / Re: Using sweet cherries
« on: October 08, 2012, 05:44:25 pm »
I would certainly reserve some for a pie! 

Jamil said in one of the podcasts (I think on Baltic Porter) that cherries are one of the harder fruits to work with.  You either have the problem of driving off too many volatiles by adding during the late stages of primary fermentation, or if you add them too late, they can sometimes just taste funny.  What many say works best with fruit is too add them after primary fermentation has completed, and to SUPPLEMENT with the same fruit extract at bottling/kegging, or slightly before.  If I were you, I would do the following:

Select a style -- I believe that american wheats and porters are several styles that work better than others with cherries.  I'm not sure if its sour or sweet (or if it matters).  Add 6 lbs of them to your batch of whatever you make after primary fermentation.  If you can puree them after thawing, do that to add surface area and pulverize the skins (sanitize your blender/food processor, though the alcohol in the beer at that point will be helpful in staving off bugs/bacteria from taking hold/multiplying).  Wait another few weeks (order some cherry extract in the meantime), let them ferment out and taste it. 

This is the best part:  draw about 8 ounces of the beer, and separate into 4 glasses.  Dose each one with increasing amounts of the extract and taste each one, clearing your palette in between (it helps to have some additional palettes/pieholes around).  Then scale it up to the amount of beer remaining prior to kegging/bottling. 

Then, once its carbed, send me a six pack.

All Grain Brewing / Last three batches terrible

Not sure if someone else said this, but could it be carbonation levels in the finished beer?  Sounds more like a water issue though.

Many ppl, including Denny, say u can skip the weights.  While it might make us feel better, I don't know that it increases the amount of aroma they impart.

Was thinking about as much as 5#, then if they ferment out, supplement it with cran extract

All Grain Brewing / Brewing for a party on a deadline.
« on: October 06, 2012, 05:20:13 am »
This looks awesome!  I might brew this real soon.  May I ask why notty tho as opposed to 001/us05? Does it bump up the maltiness or give it a light tart edge?  I just had an awful experience w s-04 is why I ask.

Anyone need one?  $140.  My wife had a work thing come up and I'm going with our two friends on Friday night.  I have it on Stubhub right now, but would rather an AHA member have it.  PM me or reply.

As I rarely take beers off the  yeast for conditioning, i typically dry-hop in the primary, in a bag, so i can take them out if it gets the flavor/aroma profile I want.  I needed the yeast cake on this one though, so I transferred to a carboy.  I probably just won't weight them next time.  Or I split it into two batches, weighted dry hops in one, equivalent weighted dry hops in the other.  I will see if myself or 10 tasters can tell the difference.

Don't worry, the chrome is in metallic form and unless you see corrosion there shouldn't be any significant chromium dissolving.  Theres chrome in stainless steel too for that matter.  Chromium is actually an essential nutrient, albeit at low levels.

Hexavalent chromium ions are the bad stuff.  The most common form is trivalent chromium.  I have not attempted to strain my brain, but I don't see why metallic chromium would be converted into the most oxidized form of chromium (hexavalent) in a reducing solution, beer.  If you haven't packaged it yet, I would bottle condition so the yeast can eat it and also make the beer even more reductive as an additional safety measure.

Have not packaged, but was planning on bottling.  Right now its sitting in a bottling bucket that has been purged with CO2 at room temp.  I introduced about 2 packs of gelatin, most of which will precipitate out, but maybe I will bottle this saturday/sunday and leave them for a few weeks.  So you think by bottling, the yeast consuming the additional sugars will cause any 'leeched' metallic chromium will precipitate to the bottom (your word, "reductive")?  Will gelatin help, or will that only cling to proteins?

Hexavalent Chromium

I'm having a tough time finding the subsection and/or appendices on "Dissolved ppm of Chromium VI when exposed to home-fermented alcoholic beverages in quantities under 5 gallons and its potential to cause renal failure or off-flavors that may cause the moron who exposed them in the first place to get points deducted in a BJCP-sanctioned competition"

Thanks!

So is that metallic taste I'm now perceiving just in my mind?!

So I've been messing with IPA recipes and techniques.  I have never bothered with trying to weight down hop bags for dry-hopping, but I thought I'd give it a try this time.  As I am not a 19th-century British schoolchild, I do not have marbles on hand, which I know are the recommended weight of choice.  I was racking my brain for something to use, then I saw my tool box.  Why not use the attachments for a socket wrench?  Stainless steel, able to be sanitized...boom, I have http://www.google.com/imgres?q=socket+wrench+set&um=1&hl=en&safe=off&client=safari&sa=N&rls=en&biw=1272&bih=605&tbm=isch&tbnid=lQ0dxi-EuUQfCM:&imgrefurl=http://www.cdsct.com/products/show-2666.html&docid=vFcwxC5ThScm5M&imgurl=http://www.cdsct.com/uploads/201008/Socket%252520Wrench%252520Set.jpg&w=350&h=262&ei=JmZrUJihMMTz0gGuqIDwAQ&zoom=1&iact=rc&dur=263&sig=103855574045057058693&page=1&tbnh=115&tbnw=154&start=0&ndsp=21&ved=1t:429,r:2,s:0,i:119&tx=84&ty=80 weights. 

Then after muscling them into the carboy neck (they bunched up in the bag and it was harder than I thought), and racking the beer, I noticed that despite the weight, the hop bags were still on top of the solution.  Fantastic.  Well the hops were wet, and hopefully it didn't matter.  Later found out that weighting down the hop bag really isn't worth the trouble. 

THEN I found out that the socket wrench attachments weren't stainless steel.  They were chrome/chromium-plated steel.  Usually for socket wrenches, they use cheap chrome.  http://en.wikipedia.org/wiki/Chromium_toxicityChrome is toxic.

So I ran home, racked the beer out of the carboy, and it does smell fantastic.  It seemed to taste good, but I haven't been feeling great and I'm not sure my palette is the sharpest. 

The attachments did not appear to have any corrosion.  There were some flecks on the inside of them, but then I looked at the attachmenets I didn't use, and they had the flecks as well.  However, I do know that beer pH is usually well below 5, and could likely corrode something like this. 

As I do not want to poison myself, my wife, friends, or family, should I dump this beer?  Its one of my better IPAs, and would sting like hell to dump it. 

Anyone familiar with corrosion of chromium on steel?

Beer Recipes / Re: Sorachi Ace in a Hefe?
« on: October 01, 2012, 08:05:38 pm »
I say go for it.  I really like Sorachi Ace and have used it a lot although more in APAs.  I can't comment on yeast interaction but I think the dill character is overstated.  I do find it has some dill character but that it seems to become more apparent, in my experience, as the beer ages.  I've said this before and others haven't agreed so maybe I'm nuts too.  I just find the character becomes more savoury with time, I think the hop character doesn't fade evenly with the lemon fading first.  If this beer goes quick, I bet you'll like it.

I'm going to disagree.  I've made IPAs, IBA's, and cream ales with Sorachis for that exact reason.  They were good, but not great.  Its kind of a tricky hop, because the lemon is there, but that savory note is a bit off to me.  They work great in a saison, but I don't dig them in hop-forward styles. 

On the other hand, other people loved the cream ale I made with them.  I just don't see how lemon/savory works with banana/clove. 

All that being said, great versions of beers have come from ideas that were thought to be crazier than this!  If you have a recipe that you can replicate and feel like tweaking it, I say brew on, brewer!

Ingredients / Re: NZ hop varieties?
« on: October 01, 2012, 08:00:20 pm »
I personally don't care for Nelson sauvin, I feel like they impart a weird vinous, tart, almost astringent character. 

No, that's why they're great. I never got the vinous thing from those hops until I picked up a bottle of NZ Sauvignon Blanc, and it's really striking how similar they are.

Yeah, it could be one of those things that its just offensive to my palette personally, because everyone else who had a Humming ale liked it a lot @ my house.  Blech though for now.  I like Sauvignon blanc too.
