"Ryori Monogatari" (tale of food) records that 'Irizake is made by putting 15-20 umeboshi, 2 sho (approx. 1.8 liters) of old sake, a little water, and a little tamari (rich soy sauce) into 1 sho of dried bonito before reducing it down to 1 sho, filtering it and cooling it, while there are some people who add 2 sho of sake and 1 sho of water before reducing it down to 2 sho; Nidashizake (extracted sake) is made by adding a little salt to dried bonito and boiling it for a while with new sake, filtering it and cooling it; and shojin irizake is made by putting chopped umeboshi and hoshi kabura (dried turnips) into grilled tofu with size of dengaku, and boiling it with old sake.'
『料理物語』によれば、「熬酒は鰹一升に梅干十五乃至二十、古酒二升、水少々、溜り少々を入れて一升に煎じ、漉し冷してよし、また酒二升、水一升入れて二升に煎じ使ふ人もある。煮出酒は、鰹に塩少々加へ、新酒で一泡二泡煎じ、漉し冷してよろし、精進の熬酒は、豆腐を田楽ほどに切り、炙つて、梅干、干蕪など刻み入れ、古酒で煎じてよし」という。
