Diesel Drafts Forums

Posted by on 30 Mar 2009 | Tagged as: links, spreadsheet

I’ve been getting a lot of feedback in the week since I launched the spreadsheet, and some feature requests.  In order to make it easier for people to discuss the spreadsheet, and share recipes I put up a forum.

http://dieseldrafts.com/forum is where you can go to ask questions about how to the use the spreadsheet, report any issues you have, request new features and discuss the development of upcoming features.

Discussion of the development will take place in the forums, so check in and let me know if you have any changes you want to see implemented in the spreadsheet.

Diesel’s Brewing Spreadsheet

Posted by on 25 Mar 2009 | Tagged as: links, spreadsheet

Diesel’s Brewing Spreadsheet is now available for public use.

A full guide and download are available at http://dieseldrafts.com/spreadsheet.

The feature set includes:

  • Worksheet – The soul of the spreadsheet, were the main action goes down.

o Batch Size is set by desired packaged volume of beer. Includes adjustments for post fermentation trub & transfer losses, kettle transfer losses, wort contraction, hops absorption, boil off rate, grain absorption, lauter tun dead space, and kettle dead space
o Mashing modes include Infusion, Decoction and Direct Heat. Predicts strike water volume & gravity, decoction or additional infusion volumes, mash out and sparge volumes. An indicator of total tun space required is given.
o Grains are selected in a dropdown that is based upon the Grains tab, all attributes of the grains are pulled from there.
o MCU, SRM, GU, Adjusted GU (based on mash efficiency), Weighted Adjusted GU (if extract is added late) are all calculated based on the weight of the grain and it’s properties on the grains tab. Extract GU Factor for weighting late additions to boil gravity is user configurable.
o Hops are selected in a dropdown that is based upon the Hops tab, all attributes of the hops are pulled from there. AA% percentage can be calculated based on hops purchase date, storage method and storage temperature.
o Utilization can be based on either Rager or Tinseth. FWH, leaf and pellet factors are user configurable. Boil gravity is the average of pre-boil and post-boil gravities.
o Yeast are selected in a dropdown that is based upon the Yeast tab, all attributes except for inventory are kept on the Yeast tab.
o Required Cell Count depends on the user configurable ale & lager factors and whether the recipe is set as an ale or lager as well as volume & gravity. Pitch volume depends on the type of yeast preparation and its cell concentration on the Tables tab.
o Pressure & Priming Sugar are shown for desired level of carbonation. User must set serving temp and choose sugar type (pulled from a select set of entries on the Grains tab). Beer temperature is assumed to be the warmest the beer was during fermentation.
o OG & FG in specific gravity and plato, ABV%, IBU, SRM, CO2, BUGU & BV are calculated for predicted and measured values and are comparable to two styles in a table.  Measurements can be entered in either Specific Gravity or Plato.  Styles can be from either BJCP or Brewers Association Guidelines.
o Mash Water Adjustments are based on the concept of residual alkalinity and John Palmer’s work. Predictions for adjusting pH, adding enough calcium and magnesium and achieving desired chloride to sulfate ratios are included. City or target profiles may be referenced in the table.
o Water attributes used in water calculation are pulled from the Water tab.
o Parti-gyle brewing mode will split the GU between the beers from the mash. The second beer’s pre-boil volume is determined by the first beer’s pre-boil volume & the parti-gyle ratio. Extracts and other ingredients added are specific to each beer, only mashed grains are split.
o Macro buttons are available to: Export the Worksheet to the Recipes file as a new tab or to overwrite an existing tab, Export the Recipe to a file for Sharing, Archive the Worksheet to a JPEG file, Add the grains, hops and yeast in the recipe which are not currently in stock to the Purchasing tab, Subtract the grains, hops and yeast in the recipe from the inventories on the Grains, Hops and Lab tabs, Toggle the Gravity Mode between Plato & SG, Reset the Worksheet to a clean starting position.
o Ample room for note taking.
