Due to a previous post of mine where I had created a recipe to match a particular style - I thought - and it proved to be wildly out, I decided to research all the approved Beer Style data and I created a spreadsheet that allows me to link my own beer recipes to the Official Style of the beer. This is so I can see where I am going wrong - or right - and improve what I am trying to do (apart from getting drunk on my own creations!) To that end I took a look at the Style listings on here that I believe (and @Pricelessbrewing please correct me if I'm wrong) that any recipe created using the editor here must look up for its reference data. The Style reference must allow for the Green Ticks and the Style listings to be updated as you build a new recipe. The only problem I have with the listing is the doubled up entries - as listed below - that have slightly different values for the same name of style. Either it is an approved style with definitive values - within the specific ranges etc. or its not. Well that's how I read a Style chart anyway. I realise the differences for each of the doubles are minor and the reference for the BJCP is different (could this be the error?) This may be a dated change i.e. some references are pre 2015 I don't know enough about these things but I don't like confusion - and I am confused to the point of doubting how to set up a specific style for certain... To me the system tells me I am within the spec of a certain style but there seems to be more to it than just aiming for green ticks. The list of the double styles I found. Tell me if I am unnecessarily concerned.
