The eighth beer that I brewed.
Tried to make another English IPA, to see if I could make it better than the first one was.
First time using liquid yeast for the primary fermentation.

Had problems with my primary fermentation, as it wasn’t achieving the OG that I expected.
The conclusion that I arrived is that I had a stuck fermentation because of underpitching, as the liquid yeast I used was at my fridge for some days.
By my calculations, by the time that I used it, id had around 50% of its original viability.
To continue the fermentation, I pitched a second yeast.
