Feed Barley I.P.A.

DSC02593

Here’s what I’ve done with some of that feed barley I malted a little while ago. I know an I.P.A. is not the best beer to judge malt quality, the hops mask a lot of the malt character but I felt like drinking an I.P.A. so I made one, so don’t judge!

It’s super tasty, I’m loving these Galaxy hops. I also dry-hopped with Mosaic. There’s a dose of peach up front followed by some citrus and ending with a strong piney bitterness that reminds you you’re drinking beer, not sangria.

I used quite a bit of caramel malt and some honey as well so it may be too malty for the style but I think it’s balanced and for me the sweetness seems to accentuate the fruity character of the hops.The Mosaic hops were sent to me from John from his families hop farm in Washington “thanks John!”

It has a nicely rounded mouth feel and as you can see in the picture a creamy head that likes to linger. O.G. was 1.059  F.G. 1.013 According to Beer Tools my efficiency was 80% What was also surprising is that I had full conversion in one hour.  Being more patient than I used to be with the germination and waiting until it’s really well modified has obviously helped in developing the enzymes in the malt.

If there is a possible flaw it has to do with a faint hint of phenolic flavour that I detected in the last beer I had which would be pretty disappointing. I can barely taste it so I don’t really care but I’ve sent this one off to be judged at the local competition, so we’ll see what the judges say about it in a few weeks. The possible source may be my water. I tried using tap water treated with half a campden tablet overnight. This is the first time I’ve tried this. Has anybody else experienced an issue with this method?

Update: This beer scored pretty low at the competition. It received a 29/50 from one judge and a 31/50 from another. However, it’s main flaw was stylistic -not enough hops and too sweet. I’m usually good at taking criticism, but I do disagree that it was low in hop flavour. Maybe the Galaxy hops threw them off? I would say they’re more peachy than citrusy but this was not noticed. According to Beer Tools this beer should have had 78 IBU’s which does not include the 2 oz of Mosaic that I dry-hopped for 5 days. Oh well.  Here’s what the judge who gave me the 29 had to say:

Aroma: Moderate grainy toasty malt. Not a lot of hops. Some citrus but very faint. No DMS, maybe diacetyl, low fruity esters. 7/12

Appearance: Hazy orange amber. Off-white moderate creamy head. Retention is pretty good. Leaves some lacing. 3/3

Flavour: Moderate caramel toasted bread crust. Hops are very faint. Bitterness is moderately low. Finishes sweet and the sweetness lingers in the aftertaste. some diacetyl maybe and low fruity esters. Moderately low alcohol. 11/20

Mouthfeel: Medium strong body with medium carbonation. Alcohol warmth is low and smooth. No astringency. A little cloying from sweetness. 3/5

Overall Impression: More like an English P.A. It feels a little under attenuated with way too high sweetness for the style. I also got some caramel which I sometimes mix with diacetyl. I didn’t feel any slickness in the mouth so I assume it was caramel which is fine but it was a little high. If you used some specialty malts it might be better to reduce them . Also the hop flavour and … was lacking a little. ( I could not make out a word, the guys writing was terrible)  5/10

At least there were no obvious off flavours. Looking at the recipe it probably was too sweet and malty. I used 11 lbs of pale. 1 lb. of caramel and 12 oz. of my brumalt. I mashed in at 143F for 15 min and decocted a gallon of mash to get to 152F for 1 hour. The final gravity was 1.013 making the ABV 6.09%

Feed barley, what to expect.

The first time I tried malting at home I used a bag of barley I bought from an animal feed store. I bought their last bag which looked really old but I was just too excited to try malting with it to care. Unfortunately when I first soaked it the water turned dark grey. It was so dirty and full of nasty bits of what looked like mouse turds I ended up throwing it out. I only paid 10 bucks for that 50 lb bag so not a major loss but still it was pretty disappointing.

Since I’m running out of last years homegrown barley I thought I’d give feed barley another try. Using feed barley seems kind of hit and miss. It’s super cheap and if you’re not growing it yourself it may be your only option but it’s worth it to find a good quality feed barley. I’ve talked to people who have a good supplier of clean barley but most often you’re likely to get barley that includes some “extras” including weed seeds.
My advice: wash, wash and wash some more. I rinsed this latest batch 10 times before the water was running clear. I bought the new bag from a different store and it’s definitely not as dirty as the first but it still contained a lot of what I thought were pebbles, turns out they’re actually small dried clumps of dirt, see the pictures below.
The difference between malting barley and feed barley is that the strains of barley classified as malting barleys have certain genetic qualities that are better for brewing like lower protein and beta glucan amounts as well as higher enzyme levels.
Here’s a list of other factors that make a good quality malting barley. For feed barley expect the opposite.

According to the Brewing and Malting Barley Research Institute (BMBRI), the following characteristics are required in superior malting barley:
Pure lot of an acceptable variety
Germination of 95 per cent or higher (three-day test)
No signs of pre-harvest germination
Protein content of 11 to 12.5 per cent (dry basis)
Moisture content to a maximum of 13.5 per cent
Plump kernels of uniform size
Fully mature
Free from disease
Free of DON mycotoxin caused by fusarium head blight
Free from frost damage
Not weathered or deeply stained
Less than 5 per cent peeled and broken kernels
Free from heat damage
Free of insects, admixtures, ergot, treated seeds, smut and odour
Free of chemical residue
These requirements will affect both the malting and brewing processes, as well as the quality of the end-product, beer.

Here’s something I got off the Ontario ministry of Agriculture website, what’s especially interesting is the last sentence.

DON, also known as vomitoxin, was the principle mycotoxin found in Ontario wheat samples in the 2000 harvest year. Its effects on horses have not been well documented. It is also called vomitoxin because it induces vomiting in pigs and dogs after ingestion of contaminated material. In various livestock species, vomitoxin will cause feed refusal, decreased weight gains, signs of gastrointestinal irritation (e.g., diarrhea, colic, rectal prolapse, and rectal bleeding), reproductive problems, skin irritation, cardiotoxicity and interference with the immune system. In mice, ingestion of DON may cause the overproduction of IgA immunoglobulins in the intestines. IgA accumulates in the kidneys and results in glomerulonephritis (kidney failure). The maximum acceptable concentration of DON in wheat intended for human consumption in flour is 1 ppm. Wheat with a concentration greater than 1 ppm will be diverted for livestock feed.

Just thought I’d throw that in there to cause some panic.

Here’s some more very interesting information in the link below on how grains are graded it includes information on animal feed. It’s nice to know that all grain is tested and regulated to this extent. It does state however that in barley meant for animal feed that .02% excreta is the maximum allowable amount. Yes it really does say excreta. If I read that right  that means that in 50lb. bag of barley there could be .16 ounces of mouse turds. I’m not sure what .16 ounces of mouse turds looks like, I just hope they float. By the way .16 oz. is 4.5 grams which is about what a teaspoon of salt weighs. For malt grade barley the number is .01%

We’ll see in a few days what kind of germination rate this barley has.

Update: After taking quite a few random samples I’ve determined that this barley has a germination rate of 80%. That’s pretty low compared to the 95% or higher expected from malting barley. It’ll be interesting to find out how those un-malted grains will affect the beer. I’ve been trying to pick out any rotten ones when I see them.
