6/17/2021 6:23 PM over 3 years ago	+5	Sample	1.012		17 °C	6/17/2021 6:49 PM over 3 years ago	From the sample point of view the grapefruit taste even from the extract is very noticeable. I am in the edge of decision that should I add the fruit there or not to boost the flavor. Gravity is also close to completion. Edit: Since this is grapefruit pale ale I decided to add the meat and zest of one grapefruit at the same time with the dryhops. I vapored water by boiling and handled the sanitization of the meat and zest by that and freezed them to extract more flavor. Also I scraped all the white pith of the zest and did 2 rounds of cold water to boil with them.

6/20/2021 2:44 PM over 3 years ago	+8	Fermentation Complete	1.010	9.5 Liters		6/20/2021 2:44 PM over 3 years ago	Took a sample and siphoned the beer to cold crashing vessel. Starting the cold crash today for multiple days. Sample has the same shitty taste that my earlier or very first grapefruit ipa had where i used the extract. So I am never going to use that again, only plain fruit and zest. But lets see how the final product will turn out. Also it would be very tempting to dry hop this one more time in the cold side few days before bottling.
6/21/2021 12:49 PM over 3 years ago	+9	Other			2 °C	6/21/2021 12:51 PM over 3 years ago	24h Crashed so added gelatin and 30g of Centennial dry hop addition. Interesting to see the effect if any on the cold side dry hop. Then this will be packaged directly from the cold crash vessel.

7/20/2021 7:17 AM over 3 years ago	+38	Tasting Note				7/20/2021 7:18 AM over 3 years ago	This beer was quite ok, not bad in any means but the grapefruit extract has to go. It just does not work well in canning.. I think it would work in a keg or something similar very well. Need to try out vodka for the zest next time. Also the malt flavor was quite strongish.. all though I think it supported this beer quite well, but it was more roasty then sweet. So I think this recipe could still be tweaked quite a bit for the next try. Color was ON POINT, this was clear really glowy RED... awesome color. On the hop point of view this was not too bitter or anything like that, but I think this could have more hops on the whirlpool side and maybe even less on the bittering side.. but definitely hopping was not too much in any means.

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.
