New Hobby: Kombucha

For my birthday which was a couple of months ago, my friend Violet (who has Many Hobbies) gave me a layer from her SCOBY and thus initiated me into a new hobby: brewing kombucha.

There are lots of online resources, but if you're not familiar with the process – which I wasn't, until recently – here's a quick summary of how to make this funky fermented tea.

The SCOBY is a living thing, short for symbiotic culture of bacteria and yeast ("yum," said my friend Abbi, when I told her what it stands for). It has the texture of a rubber mat, and typically floats on the surface of the brewing vessel.

Well, I say "typically floats", but when I started my second batch of fermentation, my SCOBY sank partially, ending up suspended halfway down the jar. I looked online to see if it's a bad sign, and found reassuring comments like "Nothing wrong with the scoby sinking!" and my favourite: "Scoby does whatever it wants to do."

Anyhow, now it floats again.

For the first fermentation (F1), you put the SCOBY, water, tea and cane sugar in a jar, cover the mouth with cloth, and let the microorganisms do their thing. I use loose-leaf oolong tea from Fujian province, purchased from NTUC. Here you see the tea being steeped in hot water, before I strain out the leaves and use the liquor for F1.

After about a week of F1, it's technically kombucha, and ready to drink. However, most people do another fermentation step (F2), which is when the drink is flavoured and carbonated.

F2 takes 2–3 days. You simply pour off the kombucha – leaving the SCOBY and a bit of extra liquid in the jar for the next round of fermentation – into a sealable container like a flip-top bottle. Then you add whatever you want to flavour it with, such as fruit juice, purée, herbs or spices, and seal the bottle. These are two bottles from my most recent batch: strawberry and mint (left) and pomegranate (right):

If the flavouring agent has some sugar content – like puréed fruit, which is a popular choice – then that should be enough to carbonate the brew. Otherwise, e.g. if you're just adding herbs or spices, you can add cane sugar for carbonation.

For my first batch, I made two bottles: dragonfruit and grape. Violet said her kombucha is not very fizzy, so I figured mine would be similar. Most people recommend F2 for 2-3 days. I gave it 3 days, to ensure adequate more carbonation. This is what happened when I opened the bottles:

The video on the left (dragonfruit) is playing at regular speed, but the one on the right (grape) is at 3x (I sped it up to fit). I suspect the grape kombucha was less fizzy because after 3 days of F2, I kept it overnight in the fridge, which slows down the fermentation process and also makes the gas more soluble.

I'm lucky the bottles didn't explode – thanks Ikea. Since then, I've reduced F2 to two days, which seems about right. My kombucha is fizzy but not excessively so.

Healthy SCOBY grows thicker with time, forming more layers – so you can peel off a layer and give it to a friend. Violet bought her SCOBY online, but then she gave some to me, and also to our mutual friends Chiok and Guofeng. So now we all make kombucha, experiment with different flavours, and compare notes. I took this pic at a recent tasting session at Chiok and Guofeng's place.

Since then, three more people have asked me for SCOBY. Soon this SCOBY will colonise Singapore, with only the wild boar for competition.

Lizards in Two Countries

I took this photo a couple of years ago in our backyard in Kolkata:


...and this one at Tampines Eco Green in Singapore:

They look different but I'm pretty sure they are the same species: oriental garden lizard, also known as changeable lizard because they can change colour. Wikipedia says:

The ground-colour is generally a light brownish olive, but the lizard can change it to bright red, to black, and to a mixture of both. This change is sometimes confined to the head, at other times diffused over the whole body and tail.

Jewel-Like Jumping Spiders

Sometime back I posted phone pics of an electric blue jumping spider, and said "someday I hope to get a good macro shot of one of these beauties".

Since then I've been carrying my camera more frequently when I go for walks in the Botanic Gardens, and keeping an eye out for spiders – and you really do need to keep an eye out, because these guys are tiny!

Besides the electric blue jumping spider (Phintella vittata) that I saw earlier, there are at least two other species with a jewel-like blue-green carapace (this post was very helpful for identification).

1. Cosmophasis thalassina (sea green jumping spider)

With their big round eyes, jumping spiders are incredibly cute and photogenic. Wikipedia describes them in more sedate terms:

the large anterior eyes of Salticidae are adapted to detailed, three-dimensional vision for purposes of estimating the range, direction, and nature of potential prey, permitting the spider to direct its attacking leaps with great precision.

2. Cosmophasis umbratica (shiny jumping spider)

3. Phintella vittata (electric blue jumping spider)

Another reason I love jumping spiders is because they are so curious, often gazing up at me and my camera – perhaps sizing us up as potential prey – and even jumping onto my bag (as in the photo above) or my arm (below). That's my forearm hair, in case you needed a reminder of how tiny they are.

Art Galleries and Beverages: London Photos

Some photos from my recent trip to London, as promised. Captions are below each photo.

Looking at art in 2024 (the National Gallery)


Turbine Hall at the Tate Modern

One-second exposure resting my camera on the railing. My friend who was with me saw the photo on my LCD and asked for a copy to hang on her wall :)

Camden Art Centre

Phone pic! I hadn't been to Camden Art Centre in all the years I lived in London. This time round, I met a friend here for coffee. I'm glad I went; it's a lovely space.

The Chandos, a pub near the National Gallery

Café in South Kensington

It would have been easy enough to straighten this in post, but I like the Dutch tilt.

Blog note: The text column of my blogposts is 580px wide. But if images are 580px wide, the image quality suffers on high-pixel-density displays like the one on my Asus Zenbook laptop. One solution is to upload 1500px-wide images, and edit the HTML code so that they are displayed at 580px. I've been doing this manually for a while, but Tommy kindly wrote some code for me which makes the process easier.

Animals in Good Light

Sometimes I think I should post animal photos only if it's (a) a relatively uncommon animal, or (b) a common animal exhibiting some interesting behaviour. But I think there's something to be said for animals in good light, even if – as in this case – they are relatively common animals, just going about their day.

The first animal literally has "common" in its name – the common sun skink. And true to its name, it was sitting in a patch of sunlight.

And this here is a white-crested laughingthrush:

Blog note: Earlier this month I wrote about moving some inactive or extinct blogs from my blogroll to my CQA page. My subset of friends who blog has dwindled since when I started out, but for the first time in years, I've added two friends' blogs to my blogroll. Say hello to Tomoe and Violet :)

Charizard

My friend's kid, who is into Pokémon, asked for a Charizard drawing, for which I repurposed a page from my UK visa application. I then cut around the drawing and made it into a card, but I think the full page is more amusing.

Balestier Buildings 1: Lam Yeo Coffee Powder Factory

I live just off Balestier Road in Singapore, and I really like the street, and my neighbourhood in general. Among other things, there are quite a few buildings with real character – interesting in a quiet way. The street is eclectic (or chapalang). There are the usual shopping malls, hotels and condominiums, but also Buddhist temples, 90s-style nightclubs, durian stalls, baroque shophouses and a Chinese opera stage.

Most of Singapore is modern – at times it feels almost too modern. But Balestier has several older buildings and establishments. One of those is Lam Yeo Coffee Powder Factory, which sells ground coffee and beans. And which I decided to try and draw.


I'm hoping this can be a series, which is why I optimistically titled this post Balestier Buildings 1. This one is a fineliner sketch, but in future I might try watercolour as well.

For me, the gold standard for this type of drawing is abbillust (no relation to my friend Abbi, mentioned previously). If I could choose between painting like Raphael and drawing like Abby – I kid you not: I would choose drawing like Abby.

Herpetofauna by Night

A few months ago I shared a photo of an oriental whip snake, but that was in the daytime. Now here's one by night, also in Pasir Ris Park:

And a four-lined tree frog (such lovely colours):


We saw a few other snakes that night: dog-faced water snakes (which I've seen before), a bronzeback, and – finally! – a mangrove pit viper. The viper was far away though, so I couldn't get a photo. Maybe one day...
