    Hello, unfortunately i couldn't find a Erlenmeyer glass larger than 2000 ml, only with an order and the time would be 2-3 weeks. What happens if i make only 2 liters of starter ? Or can i use something else ?

    i will build my own stir plate. but what method is more accurate ? c white or braukaiser ? because its a big difference between them . according to braukaiser i could make it in 1 step and with c white in 2 steps (using a stir plate) without i would need 3 steps.

    in this case i double all the numbers ? wort batch volume: 19 liters instead of 9.5 -> Yeast Cells Needed [billions] 387 initial count: 200 (i have 2 packs) volumes of each step: 3 liters instead of 1.5 step 1 & 2 and 1 liter step3 -> 405 b yeast cells but the problem is that in the...

    ok, thank you !!! and if i make 2 beers in the same week (i plan to make the dubbel and the tripel), can i make 1 bigger starter for both, or i need to make 2 separate starters ? i have 2 packs of same yeast (wyeast 1762, produced on same date)

    i hope, because if i enter for example at the date: 1st of May instead 12th, it says 0% viability. so what should i do with my old yeast ? i will try to make the starter. but i dont understand one thing: if i do a 2 step starter. first i start with 2 liters, and in step 2 (in the link you gave...

    it wasn't foam, but skim (film), don't know how to call it. just as a reminder, my batch is 9.5 liters (2.5 gallons), half of a normal batch. what do you think ?

    im a little afraid to make a starter , i tried two times to harvest yeast from trappist beers, and both times in the first 2-3 days it was ok, but after that something white formed on the surface, and it had a strange smell....

    if im low in OG, how i will add the Dry Malt Extract ? yes. i will pour the wort from kettle to fermentor, and then also stir well. also i will add yeast nutrient, which should help ? how to make an starter ? i never used liquid yeast, only dry. thx !

    my first extract - questions

    ok thanks. if i try to get an atteunation of 85% then the recipe should be modified, otherwise the beer would get to strong. here it is how it should look for 85% attenuation Tripel - ABV 8.5% (OG 1077 FG - 1011) IBU 36 - SRM 7.4 Apparent attenuation: 85% Efficiency: 60% Fermentables: 1.42...
