How Cryo hops & 'lupulin powder' removes the need for traditional hop pellets

using lupulin to make cryo hops


How 'Cyro Hops' are changing the beer brewing industry 


The concept of making beer hasn't changed much in several hundred years but the methods recently have. While hops have been used for many a year, one company in America might have found a way for a genuine step change in hop use with their innovation of collecting lupulin powder.

You might already know that lupulia is the part of the hops that brewers utilised to make beers hoppy as that's where the good alpha acids for brewing come from.

In case you didn't know, the alpha acids are converted into bitter iso-alpha acids during the brewing process, and essential oils and are what give beers their varying hoppy qualities.

YCH Hops, a grower-owned hop supplier based in Washington, America has created a new process where the lupulin is extracted from the hops and is collected in powder form and marketed as Cyro Hops.

You might well ask, what's the point of this?

Efficiency gains in making beer are the short answer.

Beer hops are often made into pellets form for distribution and preservation. The process of making the pellets actually breaks down the acids and oils meaning the effect on the beer requires more hops than one perhaps needs. Enter lupulin powder which has the superior percentage of 'herbs and spices' over hop pellets meaning that less quantity is required.
Ekuanot hops are quite popular

YCH boasts that their product "offers twice the resin content of traditional whole-leaf and hop pellet products" which basically means you only need to use half as much.

YCH Hops initially started to market their powdered 'Cyro Hops' with the brand name "LupuLN2" to commercial brewers in America.  The reviews are in and breweries switching as result.

How is lupulin powder made into cryo hops?


The powder extraction processes is simple in concept. The collected hops are subjected to cold temperatures in inside nitrogen atmosphere. This limits any oxidation of the sensitive resins and oils in the hop. The hops are 'chilled and milled' and the lupulin is forced from the lupulin gland.

The little guy has not been forgotten though - a small home brewer, you can buy the powder from Amazon!

How to use Cryo Hops

It's dead simple - you can simply dry hop the Cyro hops as you would with your ordinary pellet hops. You don't even need to make a hop tea!

What variety of cyro hops are there?


YCH Hops have produced Mosaic, Ekuanot, Citra, Simcoe and Cascade versions of LupuLN2. 

The benefits of using Cryo Hops


You can see the appeal for commercial brewers - less volume means better storage and transportation costs.

The other benefit of the powder is that their use in place of traditional hops means less 'green material' is left in the beer, improving clarity by reducing sedimentation and better beer brightness.

You can see why home brewers who don't have commercial means of clearing beer will love using the powder!

I haven't found any information how long the powder can be used before it loses its potency.

Given the apparent early success of lupulin powder with the American brewers that have used it, we expect that its popularity will slowly begin to spread across the Continent and then the rest of brewing communities the world over - provided it's sold at a cost effective price relative to the economics of using traditional hop pellets it should do well - indeed the prices on Amazon seem pretty fair.

5 mistakes EVERY beer maker should watch out for


Beer brewing can be a thankless task at times and no one will thank you if you serve them a horrible tasting home brew when you host your mates for a 'BBQ and Brews' evening.

Here are 5 mistakes that home brewers should bear in mind before they even begin to open the can of malt extract from their kit.

If you follow them well, you'll be sure to produce some delicious tasting brews.

1. Wash, wash away your sins.


We actually mean sanitize.

Sanitise the heck out of everything you use. If you're starting out as a home brewer, your equipment and kit should contain a cleansing and sterilizing agent.

You NEED to make sure that at the very least your drum is fully clean and sterilized before your start your brewery process. If brewing is going to become a hobby, sanitization needs to be a habit.

There is nothing more disappointing than going to bottle your brew and recognizing the scent of a bad brew that has been contaminated by nasty bugs.

2. Temperature 


It would be a mistake to think that homebrewing is basically a 'set and forget' process.

It's not.

Well, it can be and a key part of that is making sure that where ever you leave your beer to ferment that it's a place that has the desired temperature and that it is a constant temperature.

Don't leave your beer outside on the back porch to do its thing! Too much heat will kill the yeast so no direct sunlight. Too much cold and it will go dormant. Leave it wrapped in blankets in your garden shed if you have to, but make sure it's in a generally constantly heated place. Heating matts are pretty popular to keep beer at a constant temp.

My work colleague leaves her beer brewing in the bathtub!

3. Those bubbles...


Just because the bubbles have stopped bubbling through the airlock, it doesn't mean the fermentation process is complete.

It would be a real shame for your bottled beer to start exploding if you haven't given the beer a chance to finish the process.

Use a hydrometer to ensure the fermentation is finished before you at least consider getting that beer into glass bottles.

Hint: more experienced brewers tend to let the batch sit in the fermenter for at least a week longer than normally recommended on beer kit cans or after fermentation is complete.

In the sense that the yeast has stopped feasting on the sugars and making alcohol, fermentation has finished however there's a 'tidy up' phase where sediment falls to the bottom of the fermenter which helps clear the beer and the yeast will continue to tick things over.


3. Running before you can walk



Get the basics of beer brewing down first.

Before you run off and try and make the fanciest beer you can that features some imported yeast from England and three different kinds of hops, learn the principles of beer making.

You will enjoy your first few brewing experiences if you keep them simple. Then you can start to branch out into more complicated recipes and practices.


4. Not keeping records



If you write down what you did, what you used, when you did it and why you'll have a good basis on which to make a judgement about your beer brewing failures and successes.

If you find that you've pulled off a stunner of a beer, you might be able to figure out just exactly how that happened.

It could be the difference between remembering that you used a certain kind of hops in your brew!

5.  You drink your beer too early


Patience my young Padawan.

It is a mistake for sure to drink your beer too early.

Post-bottling, your beer needs time to carbonate. It also needs time to just chill and do its thing. The fermentation process is in a sense a simple chemical reaction but there is a complex relationship going on with the beer's ingredients that need time to sort themselves out.

The patient beer drinker who leaves his beer at least three weeks before indulging will be a better beer maker for it. If you can make it to 5 or 6 weeks before you taste, the better your beer should taste. That said, if you are keen on a hoppy beer, you can be forgiven for getting into it earlier.

What's a good ph meter for home brewing?


Coming from the clean and green wilds of New Zealand, I've never really bothered wondering about the quality of water I use with my home brewing.

In most places of NZ, the water from the tap is simply delicious, clean and quite perfect for homebrewing.

But not all water is the same.

Ever heard of a place called Flint, Michigan?

My vague recollections of 5th form science are that there's hard water, soft water and everything in between. 

And then there's the pH of water. 

But is that what we care about when making beer? 

Kind of. 

It's really the pH of the mash that brewers like to think about.

pH is the measurement of acidity or alkalinity of a solution, where the number of hydrogen ions is measured.

In the last 10 years or so, an increased understanding of the important role that the pH level of the mash plays in brewing really good beer has driven both commercial and backyard brewers to closely focus on monitoring and then adjusting their mash pH levels as required.

So what is a pH meter then?


A pH meter is a scientific instrument that measures the hydrogen-ion activity in water-based solutions, indicating its acidity or alkalinity.

The pH meter measures the difference in 'electrical potential' between a pH electrode and a reference electrode. This page has an excellent explanation of how ph Meters actually work and explains the science behind them really well.

pH meters may be utilized in many applications ranging from laboratory experimentation to quality control and checking that your batch of wine is on the correct fermentation path but for the beer brewer, we are concentrating on the beer mash. The modern food and beverage industries cannot exist without them! In terms of the home environment, many uses include aquariums, hot pools, swimming pools, home hydroponics and the like.

The best meters are leak proof, maintenance free (other than the electrodes), are robust and sturdy in that they don't break easily, and they're not affected by dirt and electrode replacement must be straightforward!

They should also be affordable and in many instances work best if handheld.

Here's 5 of the best, mid range and mid price meters that you can find online:


Oakton EcoTestr pH 2+ Pocket pH Meter


Oakton EcoTestr pH 2+ Pocket pH Meter reviewThis is a fairly popular pocket product from Oakton. The display is fairly large with a good viewing angle.

But why do brewers care about mash pH?


First of all, beers brewed within a general range of ph tend to brew better than beers that are too acidic or too low in pH.

So, brewers like to take the ph of their mash to determine if it is in the optimal range for the beer they are trying to make.

The optimal range is generally considered to be pH 5.2 to 5.4. A high reading means the beer is too alkaline.

If a brewer's meter determines the pH is too high, they will then need to adjust the level downward by adding acid or calcium sulfate.

Hopbrewer shares their advice: “The conventional wisdom is that a mash pH of 5.0-5.2 is pushing a crisper beer — you’d aim for that with a pilsner or IPA or pale ale. Once you get to a pH of 5.3-5.6, you might get more roundness and less of that tart character. But you also run the risk of extracting tannins.”

So how do I use a Ph Meter to test my beer mash?


pH meters are basically glorified volt meters that measure the 'electrical potential' produced by a special pH probe.

Using a pH meter is a fairly simple process.

One should generally draw a small sample of the wort and put in a vessel such as a shot glass. Dip the probes fully into it to get a pH reading. Make sure your device is turned on and that you have calibrated the meter first!

And remember, the mash can be hot, so be careful not to burn yourself.

THAT said, pH levels should be measured at near room temperature to get an accurate result (that's just good science). So if you could cool your sample quickly (a short time in the fridge), maybe give a stir, you'll get a genuine reading.

Don't cool it too much as you'll go below room temperature. I've read that one dude keeps shot glasses ready in the freezer to help with cooling!

Eh, that's a bit of mucking around, maybe do not worry too much....

THAT said, many of the best pH meters will have Automatic Temperature Calibration features and speaking of features...


Why do I have to calibrate my ph Meter?


You need an accurate reading so you can make the best decision for your beer!

To make a calibration curve at least three standards are needed. Without the standardized pH buffer to calibrate the meter, the results will not be accurate and thus give you the wrong impression.

PH meters can 'drift' from their calibrated settings. It is important to calibrate your pH meter often so that the accuracy of results is maintained.

What are the specifications of a good ph Meter?


The best ph Meters can have the following specifications or qualities:
  • Replaceable electrode 
  • 2-3 point automatic calibration 
  • Accuracy of 0.01 pH 
  • Portable or fixed or 'benched' depending on your need but most home brewers go portable
  • A price point between $100 - $150 gives a confidence in the quality of the unit
  • Automatic Temperature Compensation (ATC)
  • You want it built to last
  • And easy to read digital display
  • Waterproof
  • Durable sensors

What is Automatic Temperature Compensation?


Many higher quality meters use ATC functionality. This is when the unit compensates for the response of the pH meter's electrode with varying temperature.

As mentioned elsewhere in this post the mash's pH measurement is ideally conducted at room-temperature. This helps avoid measurement errors that can be caused by temperature effects on the probe and chemically in the mash.

So ATC accounts for differing temperatures of the mash.

Probes can wear out so require proper storage


Probes wear out over time and you should expect that you’ll have to replace quality ones every 2-3 years if you take good care of it and how much use they get.

The probes should be stored in a pH storage solution to preserve their lifespan. Open, dry air ruins their potential. So when buying your pH meter you need to purchase a pH buffer or 'calibration kit' .

This is why units like the Milwaukee MW102 and Omega PHH-7011 come with solutions but replacement calibration kits can be separately brought online. You might see them called 'reference solutions'. The Bluelab Combo Meter is very popular with horticulturalists and hydroponics enthusiasts (yes, even marijuana growers...)

Keeping the probe clean after each use will prolong their life - it's a good idea to clean the outside with a soft toothbrush and deionized water, being very gentle with the bulb part of the probe if this is the kind you have.

It's extremely important to never let the probe dry out and this is a common mistake when storing ph meters. To this end, it is imperative that you store the electrode as per the manufacturers' instructions.

The normal way to store the probe electrode is in the recommended storage solution which is normally a concentrated form of potassium chloride.

Be wary of buying cheap ph meters


I see the phrase "where can I buy a cheap ph meter for brewing?" all the time. While I understand money talks, I don't think cheapness should really be a motivation when buying a meter or most brewing equipment.

The cheaper the unit, the more likely you will get less than accurate readings and the units electrodes themselves will not last long if used frequently.

Many a brewer has found that by investing in a better quality unit, they get the best results. To that end, we generally recommend a price point from 100 to 150 dollars. That said you can go cray cray on price so if going high value, make sure you will get the benefit.

More serious brewers tend to go for bench top units rather than the portable kind.

You could liken it to how beginner brewers start out. The first thing they buy is a brew kettle or pot and they usually get the get the cheaper, smaller size kettle – and then suddenly they find they want to keep going with beer making and so need to purchase the bigger kettle or brewing pot. It's the same with the ph Meter - get the better one to save you having to buy another later on.

Finally, a word on pH strips


Did you ever get to use litmus paper in school science to determine if a solution was an acid or a base?

The red paper turned blue or something.

While litmus paper is a yes or no test if a solution is acidic or alkaline, the pH strip gives you an approximate measurement of the actual pH.

Thus, you can use ph strips to test your beer if you wish but those will only give an indication as to your water or brew's pH level, and will never be as accurate as a quality meter.
