Just got a bottle of Vault City Iron Brew Sour. Reserved at 7.5%, originally at 5.5%. Significant enough change in abv to warrant a new listing?
I’d say yes, that’s a 30% increase and seems to fit more in line with their imperial sours rather than their session sours. Brewery seems to think of it as a new beer on Untappd too.
I’d add it with (2021-) at the end of the name.
Added it with 7.5% in the name, as you say they do a session and series and might rebrew the lower strength version in the future. Its a bloody good beer though!
Probably need to figure out if they are done brewing the 5.5% version. If not I would recommend the abv in (7.5%) instead of year.
