Its time to report on the beer from Brewing experiment: How low can you go? where the goal was to see how much I could attenuate. Quick summary: Almost SMaSh, just 4 kg Maris Otter and "random" hops found in the fridge. Multi step mash for 2,5 hours, starting at 37°C and ending in 72°C OG 1.050 … Continue reading Followup: How low can you go?
I've been working in Copenhagen the past days. Marel has a place called Progress Point there where we can demonstrate our equipment to customers and have meetings. In the next building there is a place called "Bryg Selv" (Brew your own). I've seen it while driving to Marel Progress Point but never had the opportunity … Continue reading Bryg Selv
I've often wondered how much influence one can have on the fermentability of wort using the mash temperature. Most beers are mashed at 67°C/152°F, it is an all-around mashing temperature. But sometimes I've seen people state that they mashed on the high side 69°C/156°F or on the low side 65°C/149°F and I've wondered: Does a … Continue reading Brewing experiment: How low can you go?

The original recipe uses Perla Negra. I substituted for Weyermann Carafa Special I since it matches in °L. As far as I know, both malts were … Continue reading Photos from brewing the “Neck Tat that says Evil” black IPA
I've been collecting sensor logs from different CraftBeerPi3 users. Here is a plot of the temperature sensor signal from two different systems plotted together. One uses the ds18b20 one wire sensor and the other uses a PT100 sensor. The PT100 signal is much more noisy. It makes sense, the signal the pt100 measures is very … Continue reading Comparison of the DS18B20 and PT100 temperature sensors
