Chamomile Saison

I decided to enter a beer to a competition. What better category than herb vegetable or spice beer!

I had a bunch of chamomile from the allotment. Siobhan also brought me some chamomile flowers from work. I had already brewed this beer with broad beans. I thought it worked well, and decided to brew with beans again. This time I wanted to use dried beans because somebody on 'milk the funk' mentioned my poor extraction last time might have been because my beans were still hydrated, whilst most ingredients are dried when weighing them for a recipe. I used a ten bean mix. Initially I was going to malt them, but my malting experiment turned into a smelly mess, so I decided to just use dry packet.

The beans provide starch and protein, and the point of them was to increase mouthfeel in a low gravity beer, as well as some longer chain sugar for Brettanomyces to metabolise. In my previous beer I felt they also contributed a nice fresh but barely detectable pea/bean aroma.

The beer was 5% acid malt, 25% beans (assuming same extract potential as wheat) and 70% pale malt. The beer was 1.035 OG. the beer was bittered with Fuggles (I think!?) to 27.5 IBU and finished off with 10g of my allotment hops (mix of Fuggles and Goldings) in a 10 L batch with 10 minutes left (or no chill equivalent).

The beer was then fermented with yeast cultured from my previous batch of spelt Saison. This was mangrove jacks Belgian ale + a Brett strain, which was either Brasserie de la Senne's Bruxellensis or Orval. This problem of misidentification which started with this batch will soon come to an end, as I think I'll start with new yeast for the next batch of Saison in the summer.

The beans were hydrated/boiled for an hour before adding to the mash. My gravity was again a little low, suggesting that beans just don't contribute many sugars regardless of if they are dried or not. The liquid from the beans was purple, which I was a bit worried about, but the finished beer was a nice pale yellow. The beans really do flesh out the body of the beer, you'd not guess it it was only 1.035.

As for the chamomile, most was added at flameout, according to the recommendations in Phil Makowskis's 'Farmhouse Ales'. At bottling time, a tea was made in a French press and added just to boost the flavour a bit. I suspect the flowers added some bitterness, as the impression of this beer is quite bitter.

I've not had many chamomile beers before. This had a definite witbier feel to it, which is nice. It also had a phenolic flowery flavour. None of the nice fresh bean aroma is there in this batch, unsurprisingly, since the beans were dried. At times I feel I've been able to detect a bean flavour, that is, kidney beans, but this isn't always detectable. Despite my criticisms this beer is nice, I like the bitter dry expression, and being honest I would happily brew this again. The fact that it is 1.035 and relatively satisfying to the mouth is also very pleasing, a great table beer with a salad and some nice funky cheese. Would probably reduce the bitterness slightly next time.

The judges had mixed views. I got a score of 31, but the criticism was almost equal and opposite. One thought flavour was very noticeble, one too weak, etc. I, in the end, lost to a chile chipotle porter.

Pretty happy with this beer. A bit rough but I feel there is genius waiting to sneak out. The head is fabulous, I wonder if wheat or other grains would give retention as good.

Broad Bean Saison

On my one of the few things that will overwinter on an allotment in the UK is broad (fava) beans. A variety called "Sutton" was grown on mine, and I ended up with a couple of kg of the beans, which were blanched and then frozen. They then remained in the freezer for a year, taking up space.

They probably had been left on the plant a bit long and had got quite large and starchy. I remembered that one of the things a turbid mash is supposed to do is to contribute starches for microbes. The idea behind this being that sacc can't metabolize the starches but other bugs can.

 Someone has hypothesized that Brett doesn't really need much left behind because it can metabolise other stuff, so turbid mashing is really for other bugs, so what I'm doing doesn't make a huge amount of sense, but still.

I wanted to have another go at a saison with brett and thought the beans would be a rustic addition to a rustic beer.

I must say I was slightly inspired by CJJ Berry's excellent wine making book where the broad bean wine is celebrated as surprisingly good.  He suggests boiling the beans to extract whatever they contribute, but he suggests not letting the skins split to help the wine clear later. I'm not sure whether this is to stop protein or starch getting in the wine, but I decided I wanted both in my beer, so mashed the beans periodically with a potato masher. 

The 500g of beans started out a lovely green in 2 liters of water. At the end of an hour or so there was almost zero fresh bean aroma left and I had a grey looking sludge. This set in the fridge to a grey jelly, which hopefully means the beans had gelatinised. I froze it to preserve the goodness until I came to brew my saison.

The frozen block of beans was added to the inside of my BIAB bag, and swirled in the mash water while it heated. It surprised me how long it lasted in 70 degrees C water and actually it meant the mash water climbed all the way to 72 before it had melted the block. Adding a kilo of barley malt to the mash lowered the temperature to 68-9 degrees.

The recipe for this was 64% barley malt and 36% unmalted boiled frozen broad beans (by extract). I guessed that the extract potential of a broad bean was 1.038 which is the same as wheat as suggested in "designing great beers" by Ray Daniels. I use custom "software" to design my recipes in the form of a spreadsheet based on information from this excellent book. I wanted a very low gravity saison, I shot for 1.035 anticipating I might come a little short and 1.030 wouldn't be the worst thing in the world.

For this one I wanted to adjust my water. Bristol water is generally good for medium dark beers (bitters?). For lighter recipes, I generally have to lower the PH using a bit of HCL, and, either gypsum or calcium chloride depending on the desired sulphate-chloride ratio. The use of HCL to lower the PH normally means it is  difficult to get chloride levels bellow 150ppm-ish. For this recipe it didn't really matter and I hoped to achieve the following profile (ppm).

 

Ca	Mg	Na	Cl	SO4	HCO3
98	4	25	147	144	0.6

I'd read on a forum thread, where a bloke reports on malting lentils, that he got an iridescent shine on the bubbles on his brew. I sort of noticed the soap bubble like effect in the mash, but once the boil began the bubbles became much tighter and more matt tan. The photo below is after transfer to the fermentation vessel.

I take gravity readings at the start of the boil and then calculate what volume to brew to to get required gravity. The wort was a normal looking colour, not too grey.

This one was at 1.024 for 11L of collected wort. I chose to boil down to 9L to get final gravity of about 1.030. The wort actually boiled down much faster than expected so I had to add water to the fermenter to top up. It also darkened quite a bit. (See photo above above). This suggests the actual extract potential of broad beans is almost zero.

I used 10g of northern brewer at 60m mins for 21 IBU and then 10g of my allotment hops (mainly fuggles with a little bit of EKG) at 30mins for a further 3 IBU. This was more a romantic gesture as the beans and hops would have grown side by side last season (or saison?). No late hops for this one. The BU to GU ratio was 0.8. Refreshing but not too mouth stripping.

The wort was transferred to a brew bucket and a half package of mangrove jacks Belgian ale was pitched after an overnight cool. The yeast had been hanging around for a while (open but pegged shut). The brett I got originally  from some bruxellensis dreggs  (or was it orval? Who knows. Oops.) was pitched after 1 or 2 days. After a week or so I pitched burning sky's "saison a la provision" dreggs. I wasn't sure if I'd get much lacto expression due to the hopping.

 The beer was excellent, It was a lovely hazy yellow, the brett was very subtle and the lacto was non-existent. It just had a very bright slightly winey pale bright light flavour. This was an excellent table beer. I'm not sure what the beans really added, but suspect some of the clean fresh flavour might be from them, as well as a possible contribution to the body, although I may be completely deceiving myself based on psedo-scientific predictions about what the beans should do. I think because this was so low gravity the saison yeast was not so phenolic as it would be in a higher gravity example, which I much preferred.

One criticism would be that the hop character was a bit dull and one dimensional, a sort of slow lump of dreary just-bitter. If I were to re-brew, I would probably do either a large late addition of some floral noble hops, or I think it would work to just go wild and stick in something daft like galaxy in a large dry hop.

Excellent low gravity beer.

Spelt Brett Saison

I have really been enjoying Amos Browne's blog. One of the articles talks about his spelt saison recipe. I thought I would give it a try.

I decided to use spelt flour. This was mainly because it was easy to get, and I was confident that by mixing the flour with the grain first, my BIAB system would handle the slightly stickier mash.

The plan was to pitch some brett bruxellensis from a bottle of orval after primary fermentation was underway to get a bit of brett character in the final beer.

I used 80% pale malt (Crisp, Flagon) and 20%  organic spelt flour from dove farms. I aimed for a SG of 1.045 meaning if it really attenuates to 1.002 it is 5.64% abv. I didn't want to go much lower due to concerns about lack of mouthfeel. Bittering was with fuggles at start of boil to 28 IBU. I later dry hopped with some (15g for 10L batch) mandarina bavaria. Water was adjusted with sodium chloride and gypsum to make something vaguely like one of the water profiles in farmhouse ales, although from memory I struggled to get chloride down to the right level. Mash was single infusion BIAB at 65 C.

Yeast was mangrove jacks M27 Belgian saison ale.

Yeast was pitched, and shortly after (1 day?), brett from a relatively fresh (< 6 months) bottle of orval was pitched. Beer was left for 4 weeks, signs of airlock activity finished after 3.

I made an absolute hash of bottling. Aiming for 2.6 vols of CO2 (just in case brett takes it up further)  I had to add a liter of water to make up enough liquid for how much sugar I added to the bottling bucket, then the sugar didn't all dissolve which I noticed post bottling, so I quickly dissolved the remainder in some hot water then used a pipette to dose each bottle proportionally (I was using some 500ml beer style bottles and some 750ml champagne style bottles). Plain table sugar was used. This would normally be completely fermented by brewers yeast so I wasn't worried about the brett over-carbing, since, it too, will simply use all of it. I also gave it longer than normal to complete fermentation so hopefully no bottle bombs. Orval reportedly leave it three weeks.

The beer poured a golden yellow with a weird sudsy head that lasted a few minutes. Carbonation was high with big bubbles and quite a carbonic bite. Since brewing this beer I have had a commercial lager beer with mandarina bavaria hops, and I have determined that I don't like the tangerine pithy taste. When this beer was first tasted, the thin mouthfeel from the brett combined with the (to me) slightly unpleasant fruity bitterness combined with slight brett funk made it a little bit like when one gets a little bit of sick in one's mouth after eating an orange and then running about. However, with time the hops faded and the brett became a little bit more assertive, which was better. The weather warmed up a bit too, which made the dryness of the beer more pleasant. If I was doing this beer again I would probably get rid of the later hops and maybe add some calcium chloride to try and round out the flavor a bit.
