Sraa sar (Cambodian rice liquor) and red rice wineស្រា
Cooked rice is mixed with a dried rice-ball starter and fermented in jars for a few days, first as a damp mass and then with water added. In the household observed, the mash is then distilled into a clear liquor of about 41 % alcohol and cut with water before sale, and the spent mash feeds the household's pigs.

Recipe
Amounts from a sourceOne household observed and measured in a Takeo village. About 23 kg of rice gave on average about 24 L of spirit at 41 %, cut with well water to about 31 L at 28 %. Water is added by eye.

At a glance
Cooked rice is mixed with a dried rice-ball starter and fermented in jars for a few days, first as a damp mass and then with water added. In the household observed, the mash is then distilled into a clear liquor of about 41 % alcohol and cut with water before sale, and the spent mash feeds the household's pigs. Made in 6 steps over 4.1 days – 4.2 days. The longest step, ferment in jars as a damp mass, takes 2 days (Sakuraba Y. 2021) and runs at 30 °C (Sakuraba Y. 2021). In five Cambodian dombea starters, and in a lab red rice wine made with them and In the same lab red rice wine, Saccharomyces cerevisiae and Saccharomycopsis fibuligera were the main yeasts after fermentation do most of the fermenting.
Sraa sar is distilled, not drunk as a brewed rice wine like sato or Cambodian red rice wine. In the observed Takeo method the mash goes from cooked rice to the still in four days, and the distilling is tied to pig keeping, because the spent mash is the pigs' feed.
Red rice wine (brewed, not distilled)In a lab version of the traditional method, red rice was soaked 3 h, steamed, mixed with 2 % dried starter and held at 30 °C, 3 days as a damp mass and then 7 more days with water; it reached 11.6–13 % alcohol.
Rice liquor with tapaeRice liquor with tapae (fermented black rice) added was the usual wedding drink in the Takeo village before beer appeared.
Rice wine culture (starter making)Starters made without rice liquor or old starter, covered with leaves and not dried in the sun; seems to be the older Cambodian way.
Safety
Spent mash from the still is fed to pigs. No safety limit specific to sraa was found in the sources; the risk with any home-distilled spirit is the unknown strength and quality of each batch.
Khmer speakers call the starter (mae) dombae or mae sra, "liquor starter". A 2011 survey of 69 people who knew starter making found two Cambodian traditions, an older-seeming "rice wine culture" and a "rice liquor culture" that blows liquor over new starters. In a Takeo village survey, 65 % named beer as what they drank in 2016 and 33.3 % named pure rice liquor.
