Aha!!!That dme/lme from Bruntal seems awesome (should deliver best taste approximate to original - region wise
But unfortunately it could be also a huge guess work without 'numbers'(extract /Plato/SG & ebc).
May I suggest a partial mash recipe?
(with extract base malts and speciality, dark grains steeped, not mashed)
It's Alistair Reece's 'Morana':
(5 gallons/19 L,
extract with grains)
OG = 1 .056 FG = 1.016
IBU = 24 SRM = 26 ABV = 5.3%
3.6 lbs. (1 .6 kg) Pilsner dried malt extract
2.5 lbs. (1.1 kg) Munich liquid malt extract (late addition)
1.25 lbs. (0.57 kg) CaraBohemian®(CaraMunich® I) malt
0.45 lbs. (0.20 kg) Carafa® Special II malt
5.3 AAU Saaz hops (60 min)
(1 .3 oz./38 g of 4% alpha acids)
2.2 AAU Saaz hops (20 min)
(0.55 oz./16 g of 4% alpha acids)
0.375 oz. (11 g) Saaz hops (5 min)
Wyeast 2782 (Staro Prague Lager) yeast
My take: replace Saaz with Zatecky (almost the same, it depends whatever you can get).
And yeast, Staro Prague is almost impossible to get. Go with Kolsh strain, if you can't do lager fermentations, instead.
