Fast Pitch(tm) Canned Wort - Review

Recently, I started inventorying my brewing ingredients.  In the process, I realized that I had ordered everything needed to make a Trappistes Rochefort 10 clone recipe I'd seen a while ago.  I just didn't have the yeast.  Then I remembered that I'd bought a few cans of Fast Pitch a while ago and hadn't used them.  I also had a bottle of Rochefort 10 in the fridge.  Time to grow my own yeast!

I sanitized my one-liter flask and magnetic stirring bar.  I sprayed Star San on the bottle of beer, the opener, and the lid of the Fast Pitch can and let them soak a little.  Then I poured Fast Pitch into the flask and enough distilled water to hit the 1L mark.  I opened the bottle of Rochefort 10, poured most of it into a glass for my own enjoyment, and left about a quarter-inch in the bottle.  This leftover part I swirled vigorously until I could see no more yeast sediment in the bottom of the bottle.  I tipped this "slurry" into the flask of Fast Pitch.

To allow the starter to breathe, I stuffed paper towel into the top and did my best to ensure that it sealed the flask without blocking airflow completely.

I turned on the stirrer and let it work.

I've heard stories in years past that you "can't" culture yeast from a bottle shipped from Belgium. The theory goes that the yeast has been dormant too long and just doesn't have enough viable cells to culture.  That certainly makes sense.

On the other hand, a while ago I decided to brew a Gulden Draak clone and thought it would be good to use the actual yeast to do it.  In that case, I had the yeast sediment from four bottles of the beer to work with.  I was able to culture enough yeast through a three-stage starter to get my beer brewed. While it wasn't a perfect clone of Gulden Draak, it was a very good beer and shared many of the same characteristics.  So, I know it can be done.  Will it work with a can of Fast Pitch and the dregs from a single bottle of Rochefort?  We'll see.

A fair question to ask at this point is "Why culture up Rochefort yeast like this when you can buy White Labs' WLP530, which is basically the same thing?"  The answer to that is simple.  First and most importantly, it's an excuse to try Fast Pitch and write about it.  Secondly, I'm on-call for work and I tend not to stray far from home those weeks, so I could get my yeast without leaving home.

If you want to learn more about yeast starters, there is a good article on Beer and Wine Journal about doing it.  According to the article, I've violated one of their rules by pitching into a large starter. Well, it worked before...

March 13 9:30pm:  Dregs from Rochefort are pitched into the starter and the stirrer set in motion.

March 14 6:00pm:  I switched the stirrer off before going to work since it felt a little warm.  When I came home, there was a nice thin layer of yeast in the bottom of the 1L flask, so I created a 64-ounce Fast Pitch starter and moved the yeast to a 1-gallon jar. I left the stirrer on overnight and turned it off the next morning.

The brown ring you see at the bottom of the glass is yeast that has grown from the original Rochefort sample
March 15 6:00pm:  There's a nice thick layer of yeast in the bottom of the gallon jar now.  The wort still smells pretty sugary, so I decided to leave it going for another day.  I turned on the stirrer and let it run while I slept.

March 18 7pm:  I drained most of the wort out of the gallon jug I transferred it to, into a sanitized mason jar.  Instead of the thin layer at the bottom of the Rochefort bottle, there is now a finger-thick layer of yeast across the bottom of the mason jar (which is wider than the Rochefort bottle).  I'd say that was a successful use of the Fast Pitch wort.

Final Notes and Conclusion

I wound up using three cans of Fast Pitch to grow a nice colony of yeast from the Rochefort bottle.  That works out to around $7.50.  Certainly, a bottle of White Labs WLP530 (purportedly the same yeast strain) would have been cheaper and faster.  However, I wouldn't have the satisfaction of having brewed a Rochefort 10 clone with actual Rochefort yeast.

I've also seen people suggest that using Malta Goya (a malt-based soft drink available in many supermarkets) would be just as effective and possibly cheaper than using Fast Pitch.  It is worth noting that Malta Goya contains a lot of simple sugars which a forum discussion on Beer Advocate advised against using in a starter.  A similar product called Malta Polar is also suggested as a starter wort because it lacks some of the sugars found in Malta Goya.  I haven't tried either product, but I might someday out of curiosity.

If I was creating a wort that used a lot of adjuncts, like a Belgian Tripel, I might consider using one of the malt soft drink products (Malta Goya or Malta Polar) as a starter wort material.  I don't know that this would be any cheaper or better than Fast Pitch... so I'll probably only bother to do that if I run out of Fast Pitch and happen to stumble across one of the Malta products.

Fast Pitch is probably a bit more expensive than mixing up your own wort from DME/LME and a few hops pellets.  However, that also means boiling water, measuring, chilling, etc.  This can take quite a while.  In this case, using fresh distilled water and Fast Pitch, combined with a magnetic stirrer and stir plate, enabled me to get the yeast starter working within about 2-3 minutes of opening the bottle of Rochefort 10.  Given how little time I have available for brewing, that time savings and convenience is worth the extra couple of minutes and dollar or two.  Your circumstances may vary.

Things I've Learned Brewing with The Grainfather, Part 2

In the last post, I shared an overview of The Grainfather, recommended equipment to use with it, and an overview of the brewing process.  In this installment, I'm going to talk specifically about mashing and sparging. Having brewed over a dozen batches with it, I'm finally becoming very comfortable with the device, the mash process, and how to get what I want out of it. I don't consider myself a "master" of it yet, though.

For those who have never done all-grain brewing, I want to provide a quick overview of the mash process itself.

Mashing - With or Without The Grainfather
The goal of mashing is to turn the starches in the grain into sugars. More specifically, you want to turn the starches into a mix of fermentable and unfermentable sugars that provide the flavor profile associated with the beer you are brewing. A sweeter beer might warrant more unfermentable sugars. A more dry beer will demand few unfermentable sugars.

To a great extent, controlling the amount o…

Brewing with The Grainfather, Part 3 - Cleaning and Overall Thoughts

In Part 1 of this series, I introduced The Grainfather and discussed how to use it for mashing and sparging.  In Part 2, we talked about boiling and chilling the wort with The Grainfather and its included counterflow chiller.  In this final segment, we'll discuss cleanup and overall thoughts about the device and its usage.


Once you've pumped the wort from The Grainfather into your fermenter and pitched your yeast, you're well on your way to a delicious batch of homebrew.  Unfortunately, you've still got some cleanup work to do.

The cleanup process in my experience will take 20-30 minutes.  It involves the following tasks:

Removing and discarding the grain from The Grainfather's grain basketCleaning the grain basket, kettle, recirculation tube, and wort chillerCleaning all the other implements used in brewing (scale, scoops, mash paddle, etc.) At the end of the brewing process, there will be hops bags (if you used them), grain and other residue, and usually so…

Brewing with The Grainfather, Part 1 - Mashing and Sparging

(Important note:  This article series is based on the US version of the product.  Prices are expressed in US dollars, measurements of temperature and volume are in US units unless otherwise noted.)

iMake's The Grainfather is an all-in-one RIMS brewing system designed to be used indoors with household electric current.  It includes the kettle, grain basket, recirculation tube, pump, electronic temperature controller, instruction book, and counterflow chiller.  It does not include a mash paddle, fermenter, cleaning supplies, or pretty much anything else.  The price is around $800-900 depending on where you shop and the discounts offered.

The Grainfather handles mashing, boiling, recirculating, sparging (to a degree), and chilling of the wort.  You'll still need a fermentation vessel of some sort and some other supplies we'll discuss later.
