Seymour Tiny Hop Trial & Yeast Starter Project

Post by seymour » Fri Feb 21, 2014 2:20 am

...Being a super-easy, no-waste, quick-and-dirty, kill-two-birds-with-one-stone technique for analyzing an unfamiliar hop while simultaneously stepping-up a stolen yeast strain.

Now, I know you nerds can surely plug this into your fancy-pants brew calculators and software, and then shoot all kinda holes in my simple homespun process, but I assure you it's reliable, repeatable, very educational, and very cheap. You don't necessarily need an expensive scale, stir plate, magnetic bar, hydrometer, racking tube, flasks, air-locks, stoppers, etc…though any of the above come in handy.
95% = 84 g = .185 lb = 3 oz = ½ cup, Light Dry Malt Extract
5% = 6.8 g = .015 lb = .25 oz = 1 tsp, Molasses

+pinch of yeast nutrient (or not)
+pinch of gypsum (or not)

Top-up with water to ≈900ml which will boil-down to ≈700ml, stir well, and add

.1 oz = 2.8 g, hop variety of your choice

Boil ≈ 20 min, chill, pour through sanitized strainer into clear sanitized container with loose-fitting lid or airlock, add bottle-culture yeast of your choice. This is also a handy technique for building up a yeast starter from a bottle of your own homebrew, even years later.

Swirl the container periodically or place on a stir plate. Again, loosely cover but DO NOT SEAL THIS CONTAINER, or else you have just created a timebomb! A little piece of sanitized aluminum foil works as well as anything else. Use common sense sanitation, don't stress out. Remember, those scary infectious wild yeasts and bacterium are single-cell organisms. They don't have legs nor wings, they only get in your beer if you put them there.

Allow plenty of time for full fermentation and yeast to drop-out, move it to the fridge and wait for even more settlement. Lager it there as long as you like. When the time comes, carefully rack beer into a couple smaller bottles with a little priming sugar using a sanitized funnel. Cap the bottles and allow typical conditioning time before tasting. With regards to the left-behind yeast, use it to brew a bigger batch size or continue to step-up as desired.

Your finished beer will be something like:
OG: 1048
FG: 1010
ABV: 4.9%
IBU: ≈ 30-50 (wildly dependent on your hops variety)
Colour: 5°SRM/10°EBC, golden amber
Believe it or not, this simple "recipe" brews surprisingly tasty ale (just not enough of it!), and the tweaking possibilities are endless: quantities, adjuncts, timing, temperatures, etc, without committing much. If it sucks, no big deal. If you want to, you could whip-up a different combo every night until you run out of ingredients or containers. In the meantime, you'll accumulate lots of great yeast. And when you stumble upon a magically delicious combo, here's how you can easily super-size it:

If your typical batch size is 6 US Gallons/5 Imperial Gallons/22.7 Liters, that's equivalent to 32.4 of these tiny 700ml batches. So, whichever units you prefer, simply multiply each by 32.4, such as 6 lbs DME, .5 lbs molasses, 3.25 oz hops.

Of course, we all-grain brewers cringe at using DME for a full-size batch, so multiply the DME weight by 1.66, such as 6 lbs x 1.66 = 10 lbs pale malt. See how easy it is to try-out crazy ideas, then develop a solid starting point all your own?

Who's with me?! Feel free to add your own crazy ideas below.

This could turn out very interesting and be good to get used to single hops and a combination of hops!

Cracking idea!

Nice one Seymour! Building on that, you could collect maybe 2L of first runnings after the mash of your next brew and freeze it. Being first runnings the gravity will be through the roof and you can use this in place of dme and dilute to a sensible gravity, boil with hops and try out a new stolen yeast :) I've started doing this because dme costs a fortune compared with adding a little extra grain to a mash
Cheers and gone,

That's true, another great idea, Mozza. I always mean to do something like that, but always forget to plan ahead for it. I really should, though, in order to make these tiny hop trial & yeast starter batches even simpler.

Or even if you forget to adjust your regular brewday, you could proceed as usual, then sparge a little more water again afterwards and boil with some inexpensive sugar or corn syrup, etc, before freezing. It won't really matter that it's low gravity for the purpose of this experiment.

+1 This is a nice modification to the project :D

What is the thought behind the molasses addition or are you not after the SMASH concept and are using it in lieu of crystal? Thanks for the idea :beer:

Seems like a very good idea. I recently build a 5L output AG brewery but due to its size it really didn't pan out. It was equally the same idea that meant I could try different hops.

So my question is. With just a 20minute addition providing your bittering flavour and aroma are you getting all that the hop has to give? I'm not suggesting you aren't just putting the question out there. I guess you could do a 20 10 0 or something like that?

I think realistically extract is the way forward for this as with my micro setup it still took almost as long as it does to brew 80L

20, 10, 0
20, 05, 0 either of these are the way to go

Hi Seymour

Re the Molasses, is that Molasses sugar or Black Strap that you are using?

yup first thing i did was go straight to a yeast calculator.. ;)
one reason i haven't really done this is i'm always trying to maximise yeast growth by using a stirplate, and i don't find the heavily oxidated beer tastes that good. a few quick calculations suggest that it might often only take a coupla extra litres to get to a reasonable pitch rate with no agitation of the starter, which for a few extra bottles of hoptrial beer is no bad thing..
does dme only require a shorter boil than, say, mashing pale malt (to get hot break, etc.)? couldn't justify a 45-60min boil for this but 20mins is alright!

No, I'm definitely not getting all that any hop has to give, I won't even pretend. I'd say that for the sake of this exercise, I'm getting enough of what the hop has to give to draw useful conclusions. I want something super easy, and repeatable. Steps so simple I can memorize them and do them in my sleep, and not avoid trying stuff because I know I've got a couple hours work ahead of me. Y'know what I mean. If I boil a single hop addition for 20 minutes every time, then everything is sanitized and I get some hoppy bitterness, flavour, aroma to legitimately compare one hop variety to another. When I increase the recipe to a real batch size, I will certainly get fancier with my hop additions.

Of course, that would produce more hoppy flavours and aromas, but I have a couple reasons not to in this case. As stated, I want it as simple and repeatable as possible, keeping all other things equal. But remember, I also said this is a dual-purpose experiment. The hop trial aspect is almost secondary, mainly I want to step up my yeast and keep it pure. If you add hops at 10, 5, especially 0 minutes of boiling, you definitely risk infecting the yeast with whatever wild yeasts and bacterium are on the hops. Commercial breweries never repitch the yeast from dry-hopped batches for this very reason.

I think so too. You know I'm crazily fastidious about recipe design and all kinds of stuff when brewing my big batches, but that's an all-day affair. If a yeast starter project is at all intimidating, I'll seldom get around to it.
Normski wrote:Re the Molasses, is that Molasses sugar or Black Strap that you are using?
I guess you call it Black Strap over there, I'm talking about the glass jar of thick syrup. Treacle would be closer than the crumbly dry molasses sugar. You may have gathered I'm almost as obsessed with molasses as I am with steel-cut oats. Molasses is pretty cool stuff. Our malt provides maltose sugars, but molasses brings sucrose, glucose, and fructose; lots of diverse stuff for our young yeast to chomp through. Unlike refined sugars, it contains traces of several vitamins, and significant amount of beneficial minerals: calcium, iron, magnesium. I want to breed strong cells who'll know what to do no matter what I throw at 'em. And c'mon, in small percentages, molasses just tastes good: rummy, subtly fruity, toasty, roasty…tons of complexity from one move.

Well sure, I agree, and a beer containing too much yeast nutrient doesn't taste perfect either. But we're talking about a batch size of roughly two servings. I can suspend those preferences long enough to learn enough about a new hop to inform my recipe design for a big batch, see? These two bottles won't be around long, and aren't being shared with anyone who'll judge me.

Yes, that's the idea anyway. 20 minutes is enough to sanitize the malt and hops, and get on with my life.

Cheers!

Don't forget another cheap and easy way to try out loads of combinations is by blending. Make several brews with different hops (or different anything, really) then have a session tasting and blending them together till you like what you get. Then it's simply a matter of working back from the proportions in the blend to the equivalent recipe.

My mistake, I was thinking that the hops experimentation was your primary purpose. However dry hopping and flame-out hopping are quite different.

Oh no, you're quite right. And if anyone wanted to do tiny repeatable hop trials without repitching the yeast, those are exactly the kind of tweaks to make. I'll also say, though, if you split the hops into multiple additions we're talking about tiny quantities, just a couple grams, so it helps to have a very, very precise scale.

I started another round last night. I used the rare new American hop: Belma, split between two yeasts: Monkeybrew's Ringwood Brewery dual-strain sample and Lvivske White Lion, a really interesting wit strain from Ukraine.
