Hello Summer!

Mango Doburoku is now available at our tasting room!

MANGO DOBUROKU
100% unfiltered sake fermented with 100% real mangoes. It is now becoming our summer tradition to clean and cut mangoes in the brewery. The Doburoku base is first fermented for about 25-30 days, then we add the mangoes and ferment for a few more days, and then fermented again in the bottle to produce natural effervescence pet-nat style. The slight carbonation gives it a refreshing crisp finish to balance out the creaminess and the sweetness from the rice and the mangoes. 7.5% ABV.

STORAGE
If you’ve been taking bottles of Doburoku home, you know that our Doburoku has gotten to the point of being stable and safe to open without explosion. It took us a lot of messy trial and error (even our brewer’s kitchen has Doburoku stains on the ceiling) to get our product to this level of consistent stability without over-pasteurizing. Our tests have shown that even after a month of room temperature storage, there were no signs of re-fermentation. However, please make sure you store all our Doburoku bottles in the fridge for best taste and to prevent any yeast from re-activating.

One of the things very important to sake brewing is controlling the water absorption rate of rice. How much moisture rice has before steaming can drastically impact the taste of the final product. This is a simple breakdown of how we achieve specific target moisture level in the rice.
