Kathleen Round 4 - Split Batch

For the first brew of Kathleen for 2017 I'm trying a lot of things and making a change to the target starting gravity.  With this batch I'm going to brew 11 gallons so that I can pitch two different yeast blends and see how I like them.  I've been meaning to use both of these for a while and decided I wanted to use a familiar beer with them so that I will be able to detect the differences in each of them.  Since I've brewed Kathleen a good many times now, I know the ins and outs of it and what characters it typically brings forth. 

One of the blends I'll be using is a special release from Bootleg Biology called Saison Parfait: New World Saison Blend.  I really love the description on the website of this one.  It sounds like the perfect Saison blend to me as I love the classic peppery esters from the DuPont strains on the market, but I also love the fruity aspects of some other strains like 3726.  It also says this blend will leave a little body and good mouthfeel in the beer.  That's something I really enjoyed when using ECY08 in the beers that I've brewed with that.  At first I wasn't a fan, but after doing these beers for a while now, the added body actually helps give the beers some heft and adds to the drinkablity.  When they end up so dry as mine typically do, if there isn't any body the beers will feel astringent and can actually be a chore to drink at times.

The other blend I'll be fermenting half of this brew with is the Saison Blend II from The Yeast Bay.  I have been eying this one since it was released a while back and just never took the plunge to use it as I had so many things to use on hand. 

"Close your eyes while drinking a beer fermented with this blend, and you'll feel like you're laying on freshly turned earth in an old citrus grove."


Doesn't that sound awesome?  I can't wait to see how this blend works out.  As I stated before, I enjoy a combination of peppery earthiness and some fruity qualities in my Saisons.  I often rely on strains of brettanomyces or new world hops to get the fruity qualities so it will be nice to see what both of these blends will do.


Starters I made a few days before brew day.

Temperature mash of 149F for 75 min with no mashout.


You may notice I have slightly modified the recipe to lower the OG.  I am wanting to get Kathleen even more drinkable and shooting for slightly less ABV with this batch.  Hop amounts changed just a bit due to what I had on hand at the time. 

Like them thicky-thicks.

After the mash I began lautering and pulled the 13.3 gallons I needed for the boil.  My preboil gravity was a little higher (1.040) than my target (1.036) but instead of adding water to bring it down, I just went with it.  I boiled for 75 minutes and added my hops per the schedule above.  The SG after the boil was 1.048.  Right around where my original recipe was so I'll have to make a few changes to the grist if I want it to be lower.  My efficiency is getting better with every brew day.  Even this large 10 gallon batch I was better than my target.


Full boil kettle on this batch.

I ran wort through the chiller and divided the 10 gallons the best I could between the two FerMonster XLs.  These are quickly becoming some of my favorite fermentation vessels.  I love my Speidel still but these have a smaller footprint.  Also, you can almost get two of the FerMonsters for the price of one of the Speidels.


The Yeast Bay Saison Blend II on the left and Bootleg Biology Saison Parfait on the right.  This pic was 6-7 hours after pitching.

Both blends will be fermented "semi-open" at room temperature in my dining room.  Right now the area is sitting around 72-74F and should be perfect to test out what these will do.

I pitched the yeast blends from the starters and covered the opening with sanitized tin foil.  I press the tin foil around the top but I don't actually make an effort to seal the lid.  I usually leave the tin foil on the top for 5-7 days or until fermentation signs start to fade.  I've really enjoyed the results the semi-open fermentations.  I do them now with pretty much all my Saison ferments as well as my British ale ferments.

I will more than likely dry hop each of these and then package the beer.  Some I'll bottle fresh and unblended so I can see how the yeast blend turns out.  The rest will either be blended with mature beer or maybe even blended together.  I'll see what the beer tells me. 



Updates:

4-20-17:  6:00AM active fermentation showing on the Saison II Blend.  About 20 minutes layer, visible activity with the Saison Parfait.

4-24-17:  6:00AM activity has slowed down and the krausen is falling on both beers.  I removed the tin foil and added the cap and airlock.


4-30-17:  Activity is very slow.  The Saison Blend II has started to drop clear already.  Saison Parfait is still cloudy and looks to be full of yeast but the airlock is not bubbling.  I'll take a gravity reading this coming week and decide where to go from there.


5-2-17:  TYB Saison Blend II gravity was 1.004 and it was heavy on the phenolics with an undertone of citrus notes.  Saison Parfait was down a bit further to 1.003.  Citrus, little malt character, bit of tropical fruits, and a hint of pepper.  Both really promising.  I'll package when I get back from the Enmbrace the Funk Festival this coming weekend.

6-20-17:  I was out of Blanc hops to dry hop so I'm waiting for those to come in.  When they do I'll package a few bottles of this how they are then dry hop the rest to be blended into batches 4 and 5 of Kathleen.

Good things!

  1. Following. I have a TYB Saison Blend II split batch going, one with Beersel copitch, 10 days in. No-brett finally doesn't show airlock activity today, and copitch still slooowly going.

    1. Awesome! Keep me posted how it turns out. Yeast is still going in mine for sure.

    2. I just used this yeast blend as well, specifically because of the description. 80/20 Pils/Spelt with Liberty and Sterling finishing hops. Only two weeks in the bottle and it's tasting great. We should compare notes in a month or so.

  2. Hey dude, how do you like the FerMonsters? Do you use the bottom ports at all? Do they give you any cleaning/sanitizing issues?

    1. So far I'm loving them. This is only the second time using them for me. The first was a British Bitter. But I've been using fermentors with ports on them for years now. My Speidel and when I tried out the big mouth bubblers I had ports on them. I've never had an issue with infections and I've used brett in pretty much all of them. None of my hoppy or English beers have shown signs of brett infections and have turned out great.

      The ports are fantastic for getting the beer into blending or bottling vessels. I pretty much don't use an auto siphon at all anymore. Which is good because I've stepped on and broken more of them than hydrometers haha!

    2. Haha yeah... just had to buy two new hydrometers for that reason. Ports sound glorious. Price is right on the FerMonsters as well. Thanks!

  3. Looks amazing as always! I've got another equipment related question... I just recently started using a hop bask with 300 micron stainless mesh similar / identical to what you've got. For longer boils I feel like I'm loosing hop efficiency due to proteins and break material clogging the screen. Do you notice this as well? Do you compensate with additional hops or do you do anything special to clear the screen during the boil?

    1. I've felt the same way about hop utilization with the basket and long boils. I've started using some hop bags in larger additions as well as later additions. Then to help with the build up on the screen I tend to try and stir and scrape off as much as I can. Anything to help!

      I've talked about the same thing to a couple other people too. Seems to be a more common problem with the screens.

  4. Thank you for sharing such a knowledgeable and informative blog. If you are a beer lover then then you can find the best craft beer at German restaurant south bay.

  5. Hey Gus, have you sampled these yet? Been interested in the Saison Parfait, curious what your thoughts are, sounds like a good blend of the two classic saison profiles.

    Also when you blend for your biere de coupage, do you let the blend age for a bit because of the new Brett addition or do you package right away?

    Thanks
