How to Make a Starter in a Hot and Humid Climate

Can you imagine making and baking sourdough in a small, compact bachelor apartment in the sweltering heat, lungs muffled by high humidity?

I can, because that’s precisely what I experienced in Cambodia, Southeast Asia.

When living in the hot tropics, you may befriend your air conditioner to combat high temperatures and humidity. Unfortunately, it has its limits.

Back in September 2012, I created and nurtured my first sourdough starter, using Debra Wink’s pineapple method. However, several days after the inception of my starter, I noticed a defect on my beloved mass of wet flour. My starter, who I aptly named Abital (Hebrew for “my father is dew”), developed a thin, dry crust.

The culprit?…

Air-con, my so-called companion—you’ve betrayed me!

 

Under most circumstances, sourdough starters and bread dough needs some humidity to remain limber and healthy. Hence, starters and dough are not too fond of air conditioners. Besides the air, they can leech moisture from starters and dough, inducing them to develop dry, chapped skin. (On an additional note, air currents produces the same effect.)

Subsequent to that bleak discovery, I discontinued the use of my air conditioner during the incubation of my starter and bread baking. Because the humidity and temperature became much less tolerable, it was common for me to bake solely in my underpants. Essentially, I’d perspire profusely, glistening like a disgruntled salamander.

One major problem. After abandoning my air conditioner, the ambient temperature of my apartment skyrocketed. We’re talking above 30°C / 86°F on any given day. Consequently, a translucent, liquid substance called “hooch” kept appearing in my starter. This was a visual indication that my starter was fermenting too rapidly and starving for food.

Since then, I have learnt and applied a few lessons to reduce the metabolic rate of my starter in tropical conditions.

Avoid sources of heat:

Adjust your starter’s diet:

Personally speaking, I don’t recommend incarcerating your poor starter in a refrigerator, especially if the starter is less than a month old. Otherwise, your starter’s thriving community of bacteria and yeast may degrade and yield to undesirable microbes.

  1. This reminds me of the time when I made my sourdough here in Guangzhou, having similar conditions (up to 90% humidity). But now, we got only 17 Celsius left and my sourdough is still very active, I don’t even need the usage of a temperature box, even I got all the parts here to built one.
    Liking your blog, very beautifully done, for that reason you are in my blogroll from now on! Feel free to link back.
    Cheers from China

      Right now where I live it’s hitting about 25C at night and 35C during the day. I feed my sourdough twice on a daily basis. Doesn’t seem so hard now that I’ve had it for months.

      Anyway, thank you for linking to my blog. It’s not well known but it’s nice to spread the word.

      Cheers!

    I live in a beach town in Central Africa. Same temperature, same humidity, same struggles with stuff rotting and molding and sweating. Thanks for taking the time to post this for those of is who live in these unforgiving climates and still want to bake sourdough. I’ll try your advice.

    Though. I started waxing philosophical the other day: if it is so hard to get the whole wheat (only imported, not a local fare) and so hard to get the starter going (a real fight with heat, humidity, ingredients, bacteria, times, quantities) then perhaps it’s not appropriate for my climate and I should just take the attitude of “when in Rome…”

    • Zita says:

      Glad to be of some help!

      If you have poor access to whole wheat, perhaps you can try other grains? Teff and millet comes to mind, which if I’m not mistaken is grown in Africa. You won’t be able to produce crusty, airy breads, but you can produce sourdough flatbreads that are just as delicious.

      To get you started, I suggest doing research on “injera”, which is an Ethiopian sourdough flatbread.

    I’m living in Panama, very humid and inside my flat reaches 30 C, and so far nothing has worked for me in rising a sourdough starter, the firsnts tries, rised up tremendously the first day just to go off next one and start smelling awfull.
    Then I put them in the living room which gets the fresh air from air conditioners on the previous night and remains at about 27C. I fed them once a day, first day ok, second ok, bubbly and good smell, third day a yougurth, no more bubbles. dont know what is happening and how can I solve it, any clues??

    • Zita says:

      Hello Gerardo! This sounds normal. When making a new sourdough starter, it may smell awful, rise a lot, then appear “dead”. Don’t give up and keep feeding your starter until it is mature and active. This may take a few weeks or less if you’re lucky. Good luck!

    i just put them on the counter of my kitchen,
    one time i tried putting them in to the fridge ( because i am away for a weekend, starter is about 2 month old or so) and after i revive it, it goes ballistic, really bubbling like crazy after i fed it :)
    now its still doing fine, although the peak fermentation 9 before it deflate again) is about 4-6 hrs, so need to time my preparations well. but for feeding still every 12-24 hrs
    i live in indonesia btw

    I live in Surabaya, Indonesia. Here is hard to find a good crusty bread, so I tried to make my own crusty bread. I’ve tried to make no knead bread, but I didn’t satisfied with the result. The bread is too chewy&tough inside, the crust is too hard. This morning I begun to make sourdough starter.
    I started at 12pm, now is 9.40pm and I can see few bubbles in the starter and already smell a little bit sour. The question is when should I feed my starter? 12 hours or 24hours?
    Thanks

      Hi Stephanie,

      A number of factors will dictate when and how you feed your starter. Room temperature, humidity, hydration of the starter, etc. If kept outside of your fridge or cooler in a tropical region, fed once a day is enough if the starter is stiff. A consideration: If a murky layer of liquid (colloquially called “hooch”) appears in your starter, it means your starter needs to be fed.

      Apologies for the delayed response and best of luck!

    Thanks so much! I live in the South Pacific in PNG and have experienced the exact same problems. This post has me ready to try again.

    Hello! Zita,

    There are lots of useful tips to baking with sourdough starter.

    You said you live in a quite hot place like 25C at night and 35C during the day. I live in Japan and from June to September the temperature is similar to your place and the humidiy goes to about 98% when it’s rain. Do you keep your starter on the counter or in the fridge?

    I’ve just started baking with my own sourdough starter since May. The weather in Japan is now very suitable to sourdough starter but I’m worrying about the coming summer and thinking of how to keep my starter fit. I prefer keeping on the counter with feeding twice a day.

    If you’ve got some tips about maintaining sourdough starter in a hot and humid country, please let me know!

    Cheers,
    Ako

    I have tried to make a Sourdough bread twice, and failed on the very initial days. Like other people have mentioned, my starter was rigorous for the first two days and then dead. I live in India and currently the temperature is 40•c during the day and around 25•c during night.

    Now coming to my confusion, if I feed the starter more frequently, wouldn’t the quantity increase crazily? I have read about discarding the starter. But how much to discard? What to do with the discarded starter? Please if you can give me a good starter recipe and an advise on maintaining it successfully I would be very happy. I am eager to make my first successful sourdough bread and taste it too. So far I have only heard about how great it is. Never been able to taste it or make it. Looking forward to your reply.

      Supriya,

      I’m no sourdough expert but here’s what worked for me.

      Feed your starter every 10-12 hrs so plan the timing ahead to know what time of the day you should start at.

      If the weather is hot, put your container in a cool water bath.

      Start with a small amount. I started with 45g flour and 45g cool water. I used rye flour for mine, but I am assuming all purpose shouldn’t be different? I’m not quite sure though.

      So now you have 90g of the mixture. After 10-12 hrs, discard 60g. Mix 30g of flour and 30g of water with the remaining 30g of your mixture.

      Just keep repeating this for several days. Don’t stop even though your starter looks dead on the third day. As long as there’re no signs of molds, your starter should be fine. Try to keep on feeding, your starter should be kicking off within two weeks.

      To ensure your starter stays alive, try to keep feeding until about a month before you put in the fridge. It might be hard to keep feeding, at least try to not put them in the fridge as long as possible.

      Once you put them in the fridge, take it out to feed every week. Feed them as you normally would and put them back in the fridge after 8 hrs or so.

      If you notice that your starter rises and drops way quicker than the hours I gave, adjust accordingly. You might need to feed more often.

      Good luck!

      So after

    I live in Bangkok where it’s pretty much hot all year round so I definitely feel the pain of those who want to get started with their sourdough baking but struggle to maintain their starters. After several tries I was finally able to maintain a strong active starter which is now 4 months old. So I think it might be helpful to share success story here.

    The temperature in Bangkok goes above 30C almost year-round, except for a few weeks of “winter” when it drops to around 25C. I started my starter during that time. For my starter, I used rye flour and 100% hydration. Everything went well, I feed my starter every 12 hrs -but after two weeks or so the temperature went up to above 30C again.

    Here’s what I do when it gets warm/hot:
    1 – use cold water to feed your starter
    2 – put the starter jar in a water bath… with some ice if it’s real hot at the time. (That’s what I do now when it’s 35-39C) But just put enough ice so that the water is kept cool, don’t put so much that it becomes an ice bath!
    3 – if the starter seems to have reached it peak really quickly, try to shorten the feedings to 10hrs

    I put my starter in the fridge after about a month and a half. I take them out to feed once a week. Before putting them in the fridge, I feed my starter and put it back in the fridge as soon as it reaches the peak (about 8 hrs if put in cool water bath)

    Hope this helps!
