Notes

Grapefruit IPA:

10min end of boil:
100g of Amoretti Grapefruit Extract (if you do not have access to grapefruit extract, this will be totally different beer, so I suggest u add then at least 2 grapefruits)
Irish mosh or similar

How to add grapefruit:

Zest and juice of 1 grapefruit (remove / scrape all the pith out from the zest)
If you have package sealer, you can add the zest and juice there and add the package to a boiling water for 1 minute to kill possible nasties out
Freeze the package
Add at dry hop

Dry hop in the middle of fermentation or at the end / after fermentation.

Cold crash and gelatin for clearing. This is very beautiful if it is crystal clear.

Color of this beer is very beautiful and deep red (compliments the style very well). This is malty and very easily approachable grapefruit ipa.
