In Norway there is a tradition in a lot of farmhouse brewing to use a juniper infusion for your strike and sparge water. Basically, strike and sparge water are heated in the kettle with juniper boughs. Additionally, juniper boughs are used in the mash vessel as a filter bed/false bottom to aid in lautering.
I don’t have access to much juniper where I live, but I have a bunch of Leyland Cypress trees on my property and the boughs of this tree make a really nice tea. So I thought it would be an interesting experiment to try making beer using cypress infusion in the spirit of traditional Norwegian brewing. It didn’t hurt that I am of Norwegian ancestry either.
So I trimmed a few branches off of a tree and set up my HLT and mash vessel with a bunch of cypress boughs for the brew.
I also took this opportunity to attempt a 15 gallon batch of beer. I have a 19 gallon boil kettle so I can’t quite do a full boil without making a huge mess via boiling over but I can get pretty close. I figured I’d just top up at the end of the boil before chilling, which is what I did.
The strike water had a nice piney aroma to it, I hopped with all glacier hops, which, if you’re not familiar with them, they are described as ‘hoppy’ which seems unhelpful, but it actually fits quite well. I really like these hops and I’d like to get some rhizomes to grow them next spring.
For the 15 gallon recipe is used the following ingredients:
- Loads of spruce boughs (I didn’t weigh them) for the strike and sparge water, and also in the mashtun.
- 18lbs Pilsner Malt
- 2lbs Aromatic Malt
- 2lbs Cara-pils Malt
- 2oz Glacier Hops (first wort) @90 Minutes
- 1oz Glacier Hops @10 Minutes
- Mute Dog Abbey Yeast
- Mute Dog Palatki Yeast
- Brewery Ommegang House Yeast
Each of the three yeasts fermented a separate 5 gallon batch of the beer. I ended up unintentionally mashing a lot lower than I had planned. I think my problem is inaccurate volume measurements when I pour the strike water into the mash vessel. Anyway I mashed at about 148F for an hour and did a 90 minute boil. At flame out I topped my wort up to 15 gallons and chilled it down to 75-80F and drained into 3 separate carboys for fermenting with the three different yeasts. The OG was 1.039, one point higher that BeerSmith calculated.
After 2-3 weeks of fermentation I took some gravity readings and the gravity for each batch was crazy low ~1.001. I sampled all three batches and they were good, very dry somewhat saisony tasting. I kegged the batch that fermented with my Abbey yeast and left the other two batches alone.
After drinking off the keg for a bit, I felt like you couldn’t really taste much in the way of cypress in the beer. There was just a hint of something slightly different about the flavor of the bitterness that maybe might possibly be cypress, but it if you didn’t know about the cypress, you probably would even notice, let alone identify it as cypress.
I decided to try dry cypressing one of the other two batches. The beers had been in primary for about two months by this time. The batch with the palatki yeast looked to be forming some sort of brett pellicle so I figured I’d leave that one alone to get funky and dry cypress the batch with the ommegang yeast. I took another gravity reading and it had gone down to 0.997!
I collected 12oz of additional cypress boughs and added them to a brew bucket, then I racked the beer onto them, sealed up the bucket and put an airlock on. I let them steep for about a week before racking the beer into a keg. The beer has been in the keg for almost a week now and it is just beginning to get fully carbonated. It tastes incredible. I may have overdone the dry cypressing, it is intense in the aroma and flavor of the beer. An earthy, woody, aroma, followed by a fruity, almost christmas tree but not quite, citrusy/ascorbic acid flavor, with some malt and hop bitterness in the background.
I really like it a lot.
I’m not sure what fate lies in store for the last 5 gallon batch, I figure I’ll let it hang out for a few more months and see if the brett does anything interesting to it. I do know that I definitely like this beer and it will likely need to become part of some sort of seasonal rotation or something. I do want to see how the flavor might be different from boughs harvested in the spring vs late summer as my wife tells me she can definitely taste a difference in the tea she’s made recently vs the stuff made in the spring.
